Influence of Sodium Microalloying on Rolling Contact Endurance and Mechanical Properties of Hot-Deformed Powder Steels

Rolling bearing rings comprise a large reserve for expanding powder metallurgy production. This reserve is being incompletely implemented. The hot forging of porous preforms makes it possible to produce high-density materials for the fabrication heavy loaded wares, in particular, rolling bearing rin...
