Steel in Translation Aims and scope

Abstract

The regimes of thermal treatment Fe–30Cr–16Co powder alloys have been developed simulating production conditions. The data on magnetic hysteresis properties, phase composition after thermal treatment and mechanical properties during compression tests are presented. The influence of molybdenum and titanium in the amount of 1% on the magnetic and mechanical properties is analyzed.
