The experimental research of ductility of high-alloyed steels and nickel based alloys

Czytaj za darmo! »

High-alloy material grades are materials with high added value. For many years, we have focused on these high-alloy materials such as tool steel for hot and cold processing and nickel alloys. The material grades in question can be divided into two groups. The first group includes tool steel X50CrMoV5-1-1, X100CrMoV5-1 and Hadfield steel X120 Mn12. The second group is represented by nickel alloy[...]

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

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[...]

Selected examples of plastometric researches

A plastometric research on a torsion plastometer enables to carry out a physical simulation of forming in a wide range of deformation conditions. Two low-carbon microalloyed steel samples with different ratio of carbon, or Ceq respectively, were subjects to a simulation of structurally controlled rolling. In this way, it is possible to compare directly the values of deformation stress gained whi[...]

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[...]
