Guzey, Izdatel'stvo Moskovskogo Ur.iversiteta, 1940 copies, 255 pages) [T~xt~ ) Foreword - The materials currently used in industry operate at the limit of their potential. Austenitic heat resistant steels cannot be used at temperatures ` of more than 700�C, and the masimum temperature for the use of nickel- based alloys does not exceed 1000�C. Such parameters no lon~ir satisfy _ the needs of present-day technology. Refractory metals (tur~bs'ten, molybdenum, niobium, etc.) and alloys based on them, while displaying high mE:':~ing points, have a low scaling resistance and require protective coatings capable of withstanding the effect of aggressive media at h~.~h temperatures. Refractory nonmetallic matexials such as carbides, nitrides, _ _ etc., as well as ceramic materials, while displaying a high oxidation resistance, have low heat resistance, impact strength, and tensile strength. - These shortcomings can be eliminated by developing systems that include ~ muterials with mutually complementing propertie~`/1/. _ In the last 10-15 years interest in exploring new ways of developing high- strength str~ctural materials with a specified range of inechanical and physical properties has markedly increas~ad. Currently, as is known, a ~ steel with a maximum ultimate strength of 420 kg/mm2 has been developed. - However, the practical development of the technology of high-strength homogeneous monolithic materials does not seem feasible in view of their _ low plasticity and low ductile fracture strength. Attempts to develop high-strength homogeneous materials with satisfactory plasticity by such _ traditional hardening methods as alloying, heat treatment, various combina- tions and metalworking and heat treatm~nt, etc., have not produced the = desired results. This is because, as V. S. Ivanova /2/ points aut, the hardening produced by alloying or by thermoplastic treatment is associated with crystal - 1 - FOR OFFICIAL USE OIJLY ~ APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000100100032-4 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000100104432-4 lattice distortions of the alloy base, i.e., with an increase in the energy - = margin of the material. The ultimate limit of the energy margin of the _ crystal latti.ce due to metalworking or heat treatment is, in accordance - w1.th V. S. Ivanova's structural-energy theory, determined by the amount H of the metal's enthalpy at the melting point: Ta N = ~ CPdT, Tu - _ where Tu is the specified temperature, TS is the melting point, and Cp = is the specific heat. The ultimate dislocation density Pm correspondingly - _ computed as a function of H, at which the crystal lattice can still be conserved is limited for metals by a maximum of ^'1014 cm 2. Thus, in the _ - presence of the dislocation density of ^~1014 cm 2 the theoretical rupture _ ~ strength is practically attained, but then the degree of distortion of ~ the crystal lattice becomes such that the lattice comes close to an _ amorphous state. And indeed, thermoplastic treatment can induce in meta'.s - - only a dislocation.density of the order of 1012 cm 2, which results in materials wit'~ a specific dislocation structure and an ultimate strength - of 300-350 kg/mm2. However, a steel hardened to such a level displays - ma~or shortcomings when used as a structural material, since exposure - tc rigorous J_oading conditions (low temperatures, dynamic or cyclic loads) causes a substantial luss of strength in the presence of a defect or crack, _ so that high-strength materials may then rupture under lower stresses ~ = than m~dium-strength materials /2/. ~ Thus, 1.t is now increasingly obvious that any further advances in the _ technology of high-strength state of alloys, as reached b}~ traditional methods, collide against the insurmountable barrier of brittleness. _ _ Another major shortcoming of homogeneous metallic materials is their high = - sensitivity to the scale factor under demanding ~onditions of service. In receat years the development of a number of branches of the new technology has required materials dispiaying a combination of low density (up to 3 g/cm3), high modulus of elasticity (15,060-20,i00 kg/mm2), and a low _ - coefficient of linear expansion ((2-5)�10 deg In conventional alloys - such~a combination of properties is unattainable, since li~ht metals - (aluminum, magnesium) with a density of 1.7-2.7 g/cm3 have an elasticity modulus of 5,000-7,000 kg/mm2 and an extremely high coefficient of linear = - expansion ((20-25)�10-5 deg'1). Refractory alloys (molybdenum and tungsten) display a comparatively low coefficient of linear expansion ((4.5-6.9)� _ 10-6 deg-1) and high elasticity modulus (30,000-40,000 kg/mm2), but their - density is high, amounting to 10..2-19.2 g/cm3 /3/. ~ According to A. A. Bochvar the principal ways of enhancing the strength of m~ta.ls are: cold deformation (cold working); fusion with components entering into the solid solution based on the lattice of the base metal; . obtaining a high-disperse mixture of phases by quenching to supersaturated solid solution with subsequent tempering or aging; treatment of alloy with _ 2 = FOR OFFICIAL USE ONLY o _ APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000100100032-4 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000100104432-4 _ ~ FOR OFFICIAL USE ONLY _ ' components which, already during the process of crystallization, form a new, harder phase in the form of a network along the boundaries of grains of the = - principal phase ar in tlze form or a(skeleton) framework in a dendritic - structure. - Further hardening in each of the above cases (except casting alloys, which are not amenable to deformation) can be achieved by applying thermomechanicaY ' treatment, which induces a stable substructure. - = The simultaneous effect of all the hardening factors mentioned above is - accomplished at temperatures not exceeding (0.3-0.4) of the melting point T~. - In particular, this exactly is how steels with a strength reaching 400 a kg/mm2 have been obtained at present. When the temperature is raised to (0.5-0.6) Tm the hardtning effect of - the formation of solid solutions markedly diminishes. Hardening due to Fr � disperse segregations persists until (0.6-0.7) T~, and only an additional ' complication of the composition and structure of the segregating phases and the cilluying of the matrix solid solution make it sometimes possible to raise the operat~ng temperature of the alloys to (0.7-0.8) Tm. The advances in complex alloying combined with optimal heat treatment ~ make it;possible, e.g., to raise the level of operating temperatures of - nickel al~loys to 1000-1050�C. An additional increase in temperatures (up = to 1100�C for nickel alloys) is achieved by refinements in technology _ - (e.g., by oriented crystallization). ~ At the same time, it is perfectly obvious that the potential for further - increase in heat resistance through additional alloying is at present nearing its limit. What is more, the addition of a large number of alloying ~ - element:s produces adverse consequences: the solidus point of the alloys - decreases, accumulations of brittle phas~s resulting in a decrease in fracture strength take form, and, as a result of the deterioration in their _ plasticity characteristics, many heat-resistant alloys become unamenable to - technological treatment. This results in a marked gap between the levels = of heat resistance of casting alloys and deformable alloys. _ The eiimination of tti~: gap between the requirements of modern technology ~ of structural materials and the potential of classical alloys is achieved - by developing and using composite materials /4/. ~ For example, accordin>; to an'American forecast of the prospects for using - composite materials as_heat rasistant materials /5/, the proportion of composite materials among mat~rials used in at~iation, rocket engineering, and engine building wlll increase considerably in the immediate future. A 1970 jet engine consisted~-15 percent of alloyed steels, ^-25 percent of titanium alloys, and only 3-5 percent of aluminum alloys and composite _ materials. Superheat-resistant allays (chiefly nickel-based) accounted _ for more than 50 percent of engine weight, and are used in nearly all the - parts operating at temperatures exceeding 430�C. In 1985 superheat-resistant - 3 - FOR OFFICIAL USE UNLY - ~ APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000100100032-4 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000100104432-4 r~ux ur~r~lc:l[~L USE ONLY 1 _ alloys will continue to account for about 50 percent of engine weight, but _ the materials used in parts operating at less than 350�C wil~ change ~ markedly. Co:nposite materials will entirely supplant aluminum alloys and = partially suppl:snt titanium alloys. In parts operatin~ at up to 260�C composite materials will account for 70-75 percent of the materials used. - It is extremely difficult to define the concept of "composite material," since this term refers to a broad group of combined materials differing - in structure and in the principles for their development, and moreover e differing as regards the problems tl-rat have to be resolved for the industrial utilization of these materials. Apparently, K. I. Portnoy�s definition /3/ applies best here: "Composite materials represent an artificial bulk combination of two or more materials differing ia form and properties and ~ having distinct mutual interfaces, such that the advantages of each material are exploited." - - Thus, composite materials (or at any rate certain of their categories such as fibrous or ].aminar materials) display to a first approximation the sum of properties of their components, i.e., assure a combination of properties in a sin;le material that is not possible in a single substance. As regards the mechanism of their hardening CM can be divided into tw~ _ groups. Underlying the hardening of the first group is the principle of the reinforcement of the metal matrix by high-strength loadbearing elements. - This principle has been implemented earlier in nonmetal structural materials - such as ferrocon~rete, glass-reinforced plastics, etc. The level of the _ strength (and heat resistance) of the materials in this group depends mainly on the properties of the reinforcing elements themselves (continuous or discrete fibers in fibrous com~osite materials or flat elements in laminar rnaterials), and the role of the matrix reduces chiefly to a reclistribuL-ion of stresses between the reinforcing element. ~ In ~M of the second group, which inc~.udes dispersion-hardened alloys, the leading role in hardening belongs to structural factors. The matrix in these alloys is the principal loadbearing element, while the role of the - hardening phase reduces ch:iefly to facilitating the formation of the - dislocation substructure during the production of the alloys, especially during their deiormation and heat treatment, as well as to stabilizing that substructure under operating conditions /6/. The principal problems to be solved in order to develop materials in each group are distinguished in accoxdance with th~ above classification. The CM in the second group--dispersion-hardened alloys--do not fundamentally differ in their hardening mechanism from the classical aging alloys, the ~ - main difference being that, while in aging alloys the phase ratios are cietermiiied by the physicechemical processes of decomposition of supersaturated solid solutions, in dispersion-hardened alloys the phase ratios are ar.tif.icially specified in the production process /4/. The nrl.ncipal difficulty is of a technological nature and consists in the need to assure a uniform distribution of the fine (optimal size 0.01-0.05 }~m) hardening 4~ FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000100100032-4 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000100104432-4 - FOR OFFICIAL USE ONLY - particles (thermodynamically highly stable refractory oxides, carbides, nitrides, etc.) in the metal matrix, with a mean interparticle distance of 0.1-0.5 }un. Ttie CM in the first group are extremely varied and may be divided into lnminar. (LCM) and fibrous (FCM) compusite material~, with t}ie latter, in = t}ieir turn, being divided into those hardened by metal fibers and those hardened by nonmetal fibers. The general an3 principal problem for all these CM is the pattern of physicochemical interactiou in the solid solution - between the component parts of the composite (along with a large number of = other problems speci�ic to each kind of CM). This interaction should, on the one hand, take place to assure the bonding, so that the composite _ would perform as a single whole. On the other hand, this interaction should not develop too far, since this might result in the disappearance of the CM as such and the ultimate formation of an ordinary alloy or, in the early stages of the interaction, the softening of the hardening component. The principal obstacle to the development of heat-xesistant CM is the _ strong interaction between the matrix and fiber at high temperatures. � _ The ideal high-temperature CM should consist of components existing in - - a total equilibrium with each other within a maximally broad range of ~ temperatures. However, the ideal case is hardly achievable, since both fibers and the matrices selected must also meet other requirements, such as a high unit strength, oxidation resistance, amenability to technological processing, etc. Hence, for a proper selection of the components of a CM _ designed to obtain some particular properties, a careful study of the chemical compatibility of the materials of the fiber and matrix is needed. For a better understanding of "chemical compatibility," two terms have - been introduced: "thermodynamic compatibility" and "kinetic compatibility" /7/� - Thermodynamic compatibility is the state of thermodynamic equilibrium between matrix and fiber. It is possible only in the case of the so-called "natural" FCM, e.g., in eutectics with oriented crystallization when one - of the components acts as the plastic matrix and the other as the hardening phase. Such CM are exemplified by the systems Co (matrix)-TaC (hardening phase) or Ni3Nb (matrix)-Ni3A1 (hardening phase). In all other _ cases interaction is inevitable. Even if the change in free energy, as - computed far standard state, is positi~ve at interaction, at the initial - _ time instant, when the concentration and hence also the activity of the _ i-component of matrix in the fiber or conversely is zero, the motive power of the reaction is infinite so that ~Gi = RT ln ai; ai and 4 Gi =-00 - Hence in most cases of artificial combining of various components this can be a question on`Ly oi kinetic compatibility--the state of inetastable , equilibrium, which is affected by such factors as diffusion rate, rate of solid-phase chemical reactions, etc. 5 _ FOR OFFICIti; USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000100100032-4 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000100104432-4 r~n urrt~ttit, u~~ uivLr Any question concerning thermodynamic compatibility is answered by the correspondir.g diagram of phase equilibria. Knowledge of the diagram of state is particularly needed when developing CM for operation at high _ te~r?peratures, since the increase in temperature is accompanied by an accelera~ _ tion of the process of attainment of equilibrium and thermodynamic compati- - bility then becomes increasingly more important. For thermodynamically unstable, systems diagrams of state also are extremely important, if only - because they show the sequence of the reactions that will occur in the � system and thus make it possible to take the necessary measures to eliminate ~ - their effect. Unfortunately, so far the diagrams of state of such complex multicomponent - systems as the industrial alloys most promising in the capacity of matrices have not yet been investigated. Calculations of the free energy of reactions between matrix and fiUer components are po~sible only in rare cases, and even then they are only of an approxin~ate nature. There exists only a small number of studies dealing with research into diffusion in three-c:omponent systems, and studies of more complex systems are virtually absent. Thus, all the problems of interactfon in CM at present can be solved only experimentally, through the investigat~~n of the zones of interaction--their composition, structure, growth kinetics as a. whole, and ~ individual structural components--as a function of matrix ~nd fiber composi- tian, temperature, time, and other factors. The present monograph is devoted to an examination of the physical-chemical interaction of the components of composite material;s. Tli~~ ~inr_erest in cor~.posite mater.ial_s is very considerabl.e., This accounts for the large number of recent publications, including several monographs - /1,3,4,8-15/, dealing with all the ma,jor problems that must be resolved , = in the development of particular composite materials. That literature devotes principal attention to the hardening mechanisms and the methods of producing the materials. On the other hand, the problem of the compatibility = of various components has been relatively uninvestigated, although the solution of the question of controlled interaction is ~f fundamental - impor.tance. Without that solution research into new improved and more technol~gical methods of obtaining these material would be pointless. Iri this book attention is drawn to the physical chemistry of composite materials /16/. - The authors are indebted to Candidates of Sciences A. A. Dityat'yev, F. llunayev, and Ye. M.
