Abstract

This work studied the densification, microstructure, and hardness of Fe-Cr-Mo-B-C metallic glass alloy powder consolidated using the spark plasma sintering (SPS) process at different sintering temperatures. The results showed that the glass transition temperature of the powder was 602 °C and its crystallization temperature was 645 °C. Samples sintered at approximately these temperatures showed low densification (< 85%), whereas those sintered at 900 and 1000 °C exhibited high densification (~98%). As a result of the sintering at 900 and 1000 °C, the amorphous phase transformed into crystalline (Fe,Cr)23C6 particles and (Cr,Fe)2B nanoparticles embedded in a body-centered-cubic Fe-based matrix. The hardness of the sintered samples at 900 and 1000 °C was 899 ± 15 and 914 ± 27 HV, respectively. The obtained results showed the importance of sintering conditions in controlling the densification, hardness, and microstructural evolution during SPS.
