Abstract
It was established that hot deformation of non-equilibrium powder mixtures markedly accelerates alloy formation. Using the Ni ― Mo system as an example it was shown that an alloy in the form of a homogeneous solid solution could be obtained by hot pressing an unsintered compact. Preliminary sintering retarded the homogenization process during subsequent hot pressing, and led to the formation of an inhomogeneous multiphase alloy.
