Research on electric resistance sintering of nickel based powder

Abstract

In the paper, electric resistance sintering of nickel based powder is discussed upon. For accomplishing the research, a numerical model of powder under sintering had been developed upon applying the finite element method; in addition, calculations providing an opportunity to estimate the electric and thermal phenomena that occur during the sintering process had been performed. A sintering form for electric resistance sintering had been created as well. In addition, tests of the morphology and the microstructure of sintered specimens as well as research of their porosity had been carried out and a hardness of the specimens had been established upon applying the Vickers’ method.
