This paper reports the development of an architecture and software implementation of the library of classes for the finite-element analysis of problems in the theory of elasticity with an open-source code. The practical necessity of such systems is due to the fact that in modern equipment there are new types of materials whose structural elements'...

Cermet Tin–Ni (NiTi, Ni3Ti) as the final product of the reaction is one of the research objects. The cermets with 55 vol% Ni are fabricated by optimizing the process parameters of the thermochemical pressing method. In the process of recrystallization, the Ni–Ti solid solution forms NiTi intermetallic. When oxidized in air at a temperature of about...
