Abstract:
By using of hot tensile tests, which were realized on the simulator HDS-20, the strength and plastic properties of two progressive alloys, based on Fe-Ni-Cr (Incoloy 800HT) and Fe-Ni (Invar 36), were experimentally determined. By a special type of a tensile test, involving a continuous control heating of the tested specimens at their simultaneous load by a constant tensile force of 80 N, a nil-strength temperature of both investigated alloys was determined.

Abstract:
Using finite element modelling and mathematical processing, the universal equation is obtained which establishes the dependence of the resistance of a metal to deformation on the conditions of thermoplastic processing of alloyed low pearlite steels. The finite element method is implemented in various software packages, such as Deform-2D / 3D, etc. [..]
