Characterization and Sinterability Study of P.M. High-Speed Steel Obtained by Water Atomization
The paper presents studies about reducing the sintering temperature of PM High-Speed Steel obtained by water atomization. The powder was characterized to proceed with compaction and sintering at different temperatures between 1140-1220°C in different atmospheres: nitrogen (N2), nitrogen-hydrogen-methane (N2/H2/CH4) and vacuum. It is described the experiment in able to increase hardness by a quenching and tempering heat treatment that was carried out on sintered samples at 1140°C in vacuum atmosphere at 1200°C in N2/H2/CH4.
