Plastometric simulation of forming and cooling processes of high-carbon steels

Czytaj za darmo! »

Physical simulation of materials processing involves the exact reproduction of the thermal and mechanical processes in the laboratory that the material is subjected to in the actual fabrication or end use. This paper will focus on the physical simulations of forming processes with following cooling of high carbon bearing steels. The most significant accent for achieve desirable utility propertie[...]

Optimization of 34CrMo4 Steel Grade Properties

Czytaj za darmo! »

Inner inhomogeneities of coarse cavities type have occurred during rolling of square cross-section billets of side of which being 240 mm or 260 mm respectively from steel grade 34CrMo4 for cylinders. Due to specific technological reasons the billets are made from round cross-section continuously cast semiproduct diameter of which is 410 mm or 525 mm respectively. In this work the problem was ev[...]
