Abstract
Mechanical properties of copper alloy infiltrated M42, T42 P/M high speed steels were studied. The green compacts were sintered in vacuum at 1433, 1443, 1453 K. The skeletons were infiltrated with Cu-Cr, Cu-Co and Cu-Fe-Mn infiltrants in hydrogen or argon at 1423 K for 1.8 ks. All infiltrated specimens shrunk. The Cu-Fe-Mn infiltrated steels had the least amount of dimensional change. The Cu-Fe-Mn infiltrated steels had comparatively high hardness but low strength. Cu-Cr and Cu-Co infiltrated steels showed high strength, especially the M42 steel having a skeleton sintered at 1453 k in vacuum and infiltrated with the Cu-Co infiltrant in hydrogen had 2450 MPa of transverse rupture strength and HRC 48 of hardness.
