Not illustrated. 1920 Excerpt: ...made of the same steel, one large and one small, and both cooled in air from the annealing temperature; the smaller object will be harder and less ductile than the larger one, because of its quicker cooling. To render it as soft and ductile as the larger object cooling in the furnace may be necessary. Similarly, to give strength and high elastic limit the cooling of large objects must be more vigorously hastened than that of smaller objects as, for instance, cooling in oil against cooling in air for the smaller piece. Furnace Cooling from Annealing Temperature.--As an example of the effect of furnace cooling upon the structure of steel, let us take a steel bar J/ mcn square, containing 0.50 per cent carbon, heated to 1000 deg. C. and slowly cooled with the furnace. Its structure is shown in Figures 220 and 221. It will be seen to be composed of the normal proportions of pearlite and free ferrite, namely, some 60 per cent of the former, and it will also be noted that the pearlite is distinctly laminated (Fig. 221), and that in places at least the ferrite forms characteristic polyhedral grains. This structure is due to the slow cooling of the steel through its critical range, which permits the rejection of the full amount of free ferrite and a distinct crystallization of the constituents of the residual austenite into plates of ferrite and cementite. The relative softness and great ductility of the steel in this condition is due (1) to the presence of the full amount of soft ferrite in relatively large areas and (2) to the presence of distinctly laminated pearlite indicating the absence of hardening carbon as explained later. Air Cooling from Annealing Temperature.--To illustrate the influence of air cooling upon the structure of steel, let us take like...
