Abstract

Alloys of the Fe-Cr-Ni-Mo system have high strength, however their deformability is low conditioned by their structural inhomogeneity. A method for obtaining these alloys from the mixture of the Fe-Cr-Ni-Mo initial powders by the method of hot extrusion of the burden is proposed. The Mechanical properties are indentified and the microstructure of the obtained alloys is studied.
