TITLEs .. .. On the Geological Conditions of the Iron-Ore Horizons of Lipetsk and Tula (0 geologicheskikh otnosheniyakh lipetskoZo I tullskogc zhelezorudnykh gorizontov) PERIODICALs Doklady AN SSSR, 1957, Vol- 116, lir 2, pp. 284 - 286 (USSR) ABSTRACTt These two ore deposits were considered as results of the accumula- tion of brown iron oxides in a network of lakes at the beginning or in the middle ol' the Jurassic era, i.e. as of the same age and formed under the same conditions. It was later on proved, however# that the Tula ores irere formed In littoral-marine lagoons in the middle of the Vis6 epoch. Material for a similar revision concern- ing the Lipetsk ores also exists now. The paleontological material indicates that the Lipetsk ore horizon can by no means be younger than Lower Carboniferous. The lithological characteristics do not admit the assumption that the deposits of the ore horizon in one and the same reservoir wore accumulated with the Jurassic rocks covering it. TIfis is also contradicted by a complete absence of remaino of Jurasaio organism and by the cutting off of the ore ho- rizon by Jurassic rocks. A further precise definition of the stra- Card 1/3 tigraphic position of the Lipetsk ore horizon at first view meets . to-2-34150 On the Geological Conditions of the Iron-Ore Horizons of Lipetsk and Tula with insuperable difficulties. It is deposited on limestones of the Fran stage and is covered by Uiddle Callovian rocks. The author' a observations showed, however, that the Lipetsk ores northward rise to higher Devonian horizons and then to the Lower TournS. Nowhere, however, they lie on carboniferous (stalinogorsk) deposits. On the contrary, in the Tula and Smolensk regions iron ores were discoverei under the carboniferous deposits. The totali- ty of data leads to the conclusion that the Lipetsk ore horizon is of the same age its the bauxite horizon of the Moscow basin, and northward goes over onto the latter. It belongs to the lake stage,of facies of --,he carboniferous period. The adginal siderite nature of the Lipetak ores was supposed and provedt too. These siderites shall be considered as diagenetic. Consequently certain comaon features of the Tula and Lipetsk ore horizons are explained by their belonging to the humid formation of the Vist stage and by their common history in the Post-Paloozoic (namely washing out in the Mesozoic). The difference3between them, especially the lack of remains of marine fauna in the Lipetak ores, is explained by their belonging to different faoiec. The technological differ- ences of the Lipetsk ores, well-known to the metallurgists, are Card 2/3 to be traced to their original siderite-like nature.

Hence, it follows that effectiveness of media, in cutting of zetals, is not directly-ccrrelated with their chemical activity; their slight effect in the-ca-ae of Ag and Au is due not to the cne- mical inertness of the metal.,.,,but to mechanical properties which are unfavorable to manifest4tion of the action of the medium. In particular, there are invoLVed in these instances the extent of shrinkage of the chips a~d ene degree of adcorptive plasticizing of the surface layers of the-metal.

Moscow, AN SSSR, 1957, pp 47-56 ABSTRACT: A literature survey is presented along with results obtained in the authors' euperiments in investigating the effect of a sur- face-tension reducing medium on boundary friction (F) and wear. The experiments are founded on a method involving immersion of surfaces of F in excess lubricant (L), the latter being fluids ranging in polarity from water to non-polar hydrocarbon oils or a solution of a surface-tension reducing substance in a non-polar solvent. A schematic diagram of a new instrument for investiga- tion of the physical chemical regularities of F and wear is pre- sented. This instrument was used to study the effect of solutions of surface-tension reducing substances on the coefficient of F in Ca rd 1 2 boundary lubricalJon. It is established that in a pure benzene Effect of a Surface-tension (cant. medium the coefficient of F is not constant, but upon attaining a maximum value of rJO.7, corresponding to dry F, drops sharply to 0.3-0.4 and then again rises to 0.7, and so forth. The hypothesis is advanced that these fluctuations occurring at approximately equal time intervals, are due to in(initesmal con- ta-mination by surface-tension reducing substances not discoverable by ordi- nary methods. When surface-tension reducing substances are introduced into benzene in gradually increasing concentrations, the magnitude of the jumps dithinishes, finally disappearing, and the coefficient of F takes on a com- pletely stable value equal to rb,O.l in the case of the most powerful surface- tension reducing additives. It Ls shown that the action of lubrication under conditions of boundary F in the! case of an arbitrarily established layer of L is purely ad5orptive in nature. The adsorptive reaction, which may be pro- moted by the purely chemical bond between polar groups and atoms of metal, determines the strength of the bond of the lubricant layer and the surfaces of the metal. The phenomenon of adsorptive facilitation of the deformation and failure of solids is examined as it affects the process of adsorption fatigue and fatigue wear of microscopic asperities on the surface of mating contacts as is the effect of active media on the process of the cutting of metals.

Received 6/1957 Reviewed 7/1957 ABSTRACT First, the opinions expressed by other author in connection with this problem are discussed. The author believes that what has been said by ~.M. ROZENBERG in "The Dynamics of Milling" (1945) is, on the whole, correct, but does not serve as a sufficient basis from which to obtain a quantitati- ve expression for the depindence of the conditional cutting stress on the thickness of the cut. ROUNBERG explains the lack of direct proportionality between the cutting force and the thickness of the out by an inhomogeneous distribution of the deformation over the cross section of the cutting.kc- cording to the author's cpinion it is necessary to proceed from the point of of view of the scale factor w1wn explaining this dependence. An samples grow smaller, their properties with regard to strength are known to increase, particularly-within the range of small dimensions. It is note- worthy that the modification of these properties (in dependence of the size of the eamp1p)-is expressed by the same formula as also the dependence of the conditi6na cutting -stress depends onthe thickness of t he cut JT -;'O+(c/a).

To and c are con- stants. Cutting is a local. destruction of metal within a narrow zone with following displacement of individual 'elements of.the cutting. The details of this process of destruction are discussed in short. A conditional in- crease of sheAring strength due to a scale factor must increase cutting stre8s.

Nauk SSSR, 1957P Vol. 114P Mr 4, Pp. 764-767 (USIM) ABSTRACT: First the present stage of the problem is shortly described and reference is made to some relevant preliminary works. In the first toot series the relation between the friction layer and the adhesion of the slicte-blook to the surface of the sample was investigated. Adhesion was determined as follows: A lubricant was inserted under the slide-block which came to.s, otandstill but which was not unloaded. The stress was then determined, which is necessary for moving the slide- -mblook in a direotion opposite to that of the initial motion. When the slide-b"' oak was slowly pushed aside the tangential force increased up to a certain maximum value and then it sharply decreased. to a value which corresponds to the frictional force in the given lubricant. This sudden change Card 1/3 was usually accompanied by a characteristic sound. The author Friction as Resistance to Shear of Thin Surface Layers of 20. 114-4-24/63 Solids here equates the eAhesive power with the difference between the maximum deflaction of the dynamometer and the frictional force when a lubricant is present. The results thus obtained are compiled in a table, according to which the adhesive force does not amount to more than 15~ of the dry friction. Therefore the resistance caused by adhe ion bridges (in contrast to the opinions of various ooi:ntiato) probably constitutes only a small portion of the frictional force. The surface Eb on which the metal practically shifts during friction is considarably larger than the total surface of the,crons section of the bridges of molecular intermeshing. For the purpose of estimating So the author investigated the surface of a sample under the slide-block and then metallo- graphically determins& the plastic deformation caused by the motion of the slide-blook under the surface of the sample. If the amount of the area of displacement is correctly estimated the frictional force practically agrees with the shearing resistance of the surface layer of the metal.

The first sarioa of exparlments investigates the dupendence of the amount of the plane of displacement, of the frictional force, and of the coefficient of friction on the standard load by means of a device which Card 1/3 is similar to the device descrilyod in a previous paper by i kn Experimental Check of the Two-rerm Friction Law 20-118-6-17/43 the author (ref 1). The first diagram shows such a dependence for the friction couple: spheric ball of hardened high-speed steel-fresh-cut aluminum surface. With increasing normal load N the displacement surface gradually increases in the case of friction more slowly, however, than N. In complete agreement with the increase of the displacement surface also the frictional force P increases. The coefficient of frictionp decreases gradually with increasing normal load. This is explained by the absence of a direct proportionality between the displacement surface and the normal load. In the second series of experiments the dependence of the frictional force on the normal preetsure was investigated under following conditions: The true contact surface could develop only up to a certain strictly fixed value, and remained constant after having reached this value in spite of further inoroase of normal pressure on the contact. The special method worked out by the author for such investigations is based upon the application of a ohisel in the case of which amount of the contact surface of the front edge is strictly limited. 1 further Card 2/3 diagram illustratos the dependence of the frictional force An Experimental Check of the Two-Term Friction Law 20-1.18-6-17/43 ASSOCIATION: PRESENTED: SUBMITTED: Card 3/3 on the normal load for the friction couple high-speed steel - fresh-cut aluminum surface. The first and also the second series of experiments lead to the same final conclusions concerning the r8le of the separate terms of the two-term friction law; The Srictional force is determined chiefly by the term that'depends on-the total displacement surface deireloping in the friction. The r8le of the term which does not depend on the amount of the displacement surface and which describes thia dependence of the frictional force on the normal pressure is not so important in contrast to the opinion of several researchers.

D207/D303 Adhesion forces were nearly equal to friction forces in the case of iron, brass and copper sliders, but they were weak in the case of coconut shell, ivory and the Mg alloy. In all cases the friction force per unit actual contact area was approximately equal to the shear strength of tin or lead. These facts indicated that friction was primarily due to surface roughness (slip in the top layers of lead or tin, scratching of lead or tin by the harder sliders, shear of microscopic projections) rather than to adhesion (stick- ing together of smooth surfaces). This conclusion was confirmed by further experiments on friction during planing of lead and tin by cutters made of the same materials as the sliders, and by experi- ments on sliding a metal rod with a hemispherical end on aluminum.

The friction theories prevailing at present are based on the incorrect concept that the real area of friction is the area of contact of the rubbing pairs. This complicates understanding the process of external friction and also complicates the physical interpretation of experimentally established facts. This relates particularly to the dependence of the coefficient of Card 1/6 external friction on the normal load. In earlier work one of the authors of this paper (Refs 8-10) applied SOV/139-59-1-6/31+ Investigation of the Depondence of the Friction Force on the Real Area of Friction and the Formal load the concept of V. D. Kuznetsov (Ref 1) and of Bowden and Tabor (Ref 12) on the physical nature of the process of external friction and attempted to justify the point of view that this process consists basically of plastic shear which proceeds inside relative~r thin surface layers of the rubbing pairs. As a result of this, the real friction area Is that along which the process of shear takes place dixring friction. This point of view follows directly from analysis of the basic types of interaction of solid surfa.-.es which bring about external friction (Refs 8,9), To verify experimentally this concept, the friction was studied of a semi-spherical slide block made of hardened steel along freshly out surfaces of the following metals: tin,, lead, aluminium, copper, zinc, bronze, steels 45 arid U12, Iron, alloys E1437, VT2 etc. It was found that displacement of the slide block along a freshly cut surface of the specimen brings about the Card 2/6 formation of a "stagnant" zone (build-up) and that the displacement of the slide is not effected by external SOV/139-59-1-6/31+ Investigation of the Depondence of the Friction Force on the Real Area of Friction and the Normal Load sliding along the surface of the specimen but by shifting (sheal-) along the internal boundary of this zone. Thus, ixt the case of pure metallic rubbing pairs, the friction does not consist in cutting off the molecular brideps occurring at the points of physical contact5 as waE suggested by Bowden, but by shear along the internal surface of the "stagnant" zone. On increasing the normal load N there will be an increase in the real area of friction 8 and of the friction force. Thereby I, with increasing N the specific friction force f will remain practically unchanged and will equal approximately the shear strength of the material of the specimen (Ref 10); this indicates that the friction force is determined de facto by the friction surface and is almost independent of the normal pressure. Since this latte~r conclusion is considered of great importance, the authors studied the behaviour of the friction force under conditions such that the friction Card 3/6 area remained practically unchanged in spite of the continuous incroase in the normal load. These experiments SOV/139-59-1-6/34 Investigation of the Dependence of the Friction Force on the Real Area of Friction and. the Normal Load were carried otit by means of a cutting tool with a limited fricticn area. In the experiments chips of a pre-determined thickness between 0.02 and 1.0-3.0 mm were planed off' by means of a specially built cutting tool, a sketch of which is shown in Fig 3, p 38. This tool consisted of a high speed steel wedge with an an&le of 300 at the apex and a facet with an angle of 25u, whereby the width of the facet varied between 0.2 and 1.0 mm. In Fig 5 the dependences are graphed of the horizontal and the vertical components of the planing force of brass as a function of the depth of out. Fig 6 shows a typical curve of the dependence of the friction force on the normal force applied during planing of aluminium by means of the special cutting tool used in the experiments which had a limited area of friction. In Fig 7 the depenhence is graphed of the friction force on the normal force for iron, copper,, brass, aluminium, Card 4/6 lead and tin. It can be seen from the graphs, Fig 77 that qualitatively the picture is the same for all metals.
