Transformations during liquid-phase sintering of high-speed alloy powders

Abstract

The laws of phase and structural transformations during sintering of pressed powder mixtures of high-speed steels with different carbon content (0.2% and 3.8% by mass) are investigated. Established regular changes in the characteristics of the structure, depending on the quantitative ratio of the components and the duration of diffuse processes during sintering.
