I. A. Rinebolt and W. Y. Harris (Ref.4) published results of investigations of the se-parate.influence of P and 11i on the cold brittleness of steel. However, as far as the authors are aware the simultan6ous influence of these elements has not been /Studied. Furthermore, the influence of these elements on the cold brittleness was studied predominantly, on low, carbon steels, usually not exceeding 0.201o' and in no case exceeding 0.3%. Such limitation of the carbon content in the investigations is inadvisable since it was established that with increasing carbon content the Card 1/6 unfavourable influence of P increases and the favourable BOV/126-6-3-17/32 Influence of Phosphorus and Nic1,el on the Cold Brittle ne E--,s of L Medium.Carbon Steel 'nfluence of Ni decreases. The'authors of this paper investigated predu~ainDntly the cold brittleness of steels containinS 0.50-/% C. Three heats were produced in a hii~h frequency acidioally lined furnace with a P content up to 0.15% and Ni contents up to 2yo (heats 1-3, Table 1). in additiDn, four more heats were produced UT-os 11-71 Table 1) with P contents up to 0.25% and other variations in the contents. Specimens from these steels were tested in the forged state and in the normalised state using standard notched specimens. The 0tests v-.,ore effected in the.temperature range +20 to -50 C. testinS at each temperature 5 to 7 specimens of each heat. The graph Fifsl, shovii3 -the temperature dependence of the impacl str ngth of carbon steels with various C contents and of 0.3% carbon steels with various P contents.

F dissolves preferentially in the ferrite and,not in -the austenite and does not influence appreciably -the eutectoidal content of carbon. The micro-hardness of ferrite increases continuously from 131 to 241 units if the P content is raised fi-om 0.11 to 1.42clo. The influence of P on the cold. brittle- ness cannot be explained solely by its influence on the srain size. it has-also to be oxplained from the point of view of its influence on the properties of the solid solution. The assumption has been expressed thet P influenceo the ~-,tructure of the crystal lattice and brings about an increase of the resistance to displaceiLierit at lower temperatures. The results of i(apact tests on stee-ls containing 0.1,90/o P and alloyed with various contents of Ui are entered in Table 2 and f-,rraphed in Fig.2. The results obtained with the three steels indicate that an Card 3/6 increase in tlte Ni content brings about a progressive .90V/126-6-3-17/32 Influence of Phosphorus and Nfic'L_--el on the Cold Brittler-ess of Medium Carbon Steel shift of the upper limit o'f the critical temperature of brittle fracture; nickel also increases appreciably the .impact strenSth in the case of brittle fracture xith increaBing P content. Thus, on the average at -50 C the steels 1 72 7 3 (Table 2) aitYi nickel contents of 01 1.08 and 2.OL~910 have impact strengths of 0.3, 0.5 and 2.0 kgia/cm2 respectively. The micro-structure of phosphorous steels shovxs a characteristic anomaly; in the belcw-eutectoidal steels the presence of two ferrites can be observed, a P-enriched "relief" ferrite and "ordinary" ferrite surrounding it which is P-impoverished. Within the limits of concentrations pertaininS in the test.5, the F content does not influence appreciably, the position of -the eutectoidal point as the carbon content. FiSs.3-5 show soi,lie of the obtained raicro-stimctures. In view of the fact that an increased pearlite content i,~ias anticipated to brino about reduction in the mcuamum impact- strenE;th,, whilst the presEnce of' Ni in the ferritic matrix should bring about Card 4/6 an increase in the impact strength of the steel durinE~.- SOV126-6-3-17/32 Influence of Phosphorus and Fickel on the Cold Brittleness of Medium Carbon Steel brittlefracture, the authors iiivestigated the influence of Deat treatmeat,consisting of haEdening in water from 850 C followed by.tempering at,650 0 for one hour,, as a result of which a disperse uniformly distributed granular cementite was obtained in a fine grain ferritic matrix. in Fig.6.the impact strength vs. temperature curve is given for one of the tested steels in the initial normalised state/ as well as after the here mentioned.heat treatment. It can be seen that the temperature of transition into the brittle state is not appreciably affected by such a heat treatMent but the impact strength is 2consideEably improved ~:Y it ang increases to 3.6 kg/cin at +20 C and 1.8 kg/cm at -40 C as a result. It can, therefore, be concluded -that the -temperature of appearance of the first signs of b:rittle fracture and the temperature of the complete t::-ansformation of the steel into the brittle state are determ.ined fundamentally by the properties of the ferrite, whilst the magnitude of the impact strength in the tough state is limited by the quantity of pearlite in the Card 5/6 normal case andl Linder special conditions, by the shape of SOV/3.26-6-3-17/32 Influence of Phosphorus and E'ickel on Lhe Cold Britl;lenes,- of Medium Carbon Steel the ceracntite separations'and its distribution inside the ferritic matrix.

(Ref 1) expressed the desirability 'for a special heat treatment to be worked out.which would bring about isolation of a considerable quantity of P in "relief" pearlite, thus lowering the temperature at which cold shortness sets in. The authors of this paper decided to explore the possi- bilities of such a heat treatment. First, the influence of P content on the temperatures of the Acl, A .3 and Acm points were investigated, the methods adopted being Cardl/5 based on the work of Oelsen (Ref 5). C and P behave SOV/12&-6-5-14/43 influence of Heat Treatment on the Structure and bold Shortness of Phosphor Steel differently both qualitatively and quantitatively in a band y-iron; they rapidly redistribute themselves during phaso changes, P mainly concentrating in ferrite and C mainly in austenite. This non-uniformity in distribution remains after the phase changes are complate. Steels of various 0 and P content were tested dilatometrically at a heating and cooling rate of 3 C/min, excSpt in cases where the critical points were above 1 000 0 orikere the temperature of completion of dissolution of secondary cementite in hyper-eutectoid steels-was used for deter- mining the critical points,.when a micro-structural method was used. The results are shown in Figures 1 (heating) and 2 (cooling) in the form of graphs (temperature agairst % C) for steels of various P contents. Figure 3 shows the boundaries of the one-phase region of austenite in relation to P content for steels of constant C content. ,In Figure 4, experimental and theoretical curves for the beginning and completion of the a to y transformation on heatinEr steels with a constant P content are shown. Card2/5 Figure 5 is a micro-photograph of 0.8% C, 0.3% F steel, SOV/126-6-5-14/43 influence of Heat Treatment on the Structure and Cold Shortness of Phosphor Steel cooled fr8ia the one-phase region of austenite and quenched from 850 0 after 15 minutes' soaking. Martensite, cementite ;md ferrite are evident. The same alloy slowly cooled is shown in Figures 6 and Here, the pearlite is a network of ferrite within which again there is a network of cementite. The absence of phosphide in these micro-sections is probably due to redistribution of 'the dissolved phosphide between the a and y phases. In order to estimate the phosphide in ferrite, the micro- hardnv)s was plotted against % P (see Figure 8) and from this diagram the relief ferrite in steels containing 0.3 to 0.4916 C and 0.15% P was found to contain 0.25 to 0;97000 P and that in 0.5 to O.rffo C steels, 1.2 to 1.5% P. The F content of the ferrite network containing the cem-entite network was 1.21 - 1-36%, which approaches thS solubility of P in a-iron at temperatures of 800 to 870 0 at w1aich the austenisation of steels containing 0.2 and 0.3016 P is complete. A F content exceeding 0.05% reduces the strength of.steel. The reasons for this have remained Car4W. obscure until recently., The authors of this paper, in an SOV/126-6-5-14/43 Influence of Heat Treatment on the Structure and Cold Shortness of Phosphor Steel effort to elucidate this problem, have carried out the following experiments:, refined steel containing 0.48966 0. 0. 142~% P 1 0. 228Yo Si, 0. LVW6 Mn and 0. 26% S was cast into small ingots which were forged into rods. These in tLlxn were cut into billets for making stgndard test pieces. The billets were normalised at 800 0 and one half of them were made into test pieces for an impag-t test; the other half were heated to and soakedat 760 C for one hour and th8xl air-cooled. Sharpy.. impact tests- were carried oat at 0 0 and vetrious temperaturea below. The results are given ina table and in Figure 9. The impact strength of the latter specimens is greater at all testing tempara.- tures than that of the former.. Their micro-structure is shown in F-J.1gure 10 and approaches that aimed at. The microhardnoss of the isolated islands of "relief" ferrite was found to be 216 kg/mm2 the- t of the surrounding ordinary fe kg/mm Such a hardness of "relief' =ite 135 ferrite suggests a P content of up to 1%.

On decrease of the modulus from 10 to 6.2 and the amount of NaOH from 40 to 25% of the weight of hydrolys .is lignin the yield of acti- vated lignin decreases slightly and its concentration in the solution increases from 7 to 11%. At the same time concentration of the re- sidual free NaOH decreases by more than 2 times, and its expenditure per one kg of activated lignin to 0.33-0-35 kg.

The article is based on.a report by Engineer Beri on,the 29th International Congress of.Industrial Chemistry in Paris in 1956. The apparatus consists of a column with built- in deflectors arranged opposite one another, under a certain angle, in such a way that the steam.entering at the bottom mixes in the contact chamber with the-liquid. Due to the design of the column both phases, the liquid-and the gaseousq, pase through the contact chamber almost.horizontally and subsequent- ly follow separate movements, one*in the direotion of the light fraction, the other in the direction.of the heavy fraction. The Card 1/2 process is illustrated by two schematic diagrams. The K.A.F.L. SOV71-59-3-9/23 Rectification Apparatus of the System "Pulverization by Impact" Company turns out rectification units for purest ethyl alcohol, distilled from molasses and starchy.mat'erial. The columns, made of acid-resisting steelq are simple in design and supposed to consume 45 kg of steam per 1 dkl.of waterless alcohol. There are 2 schematic diagrams.
