摘要

Preliminary investigations of a new high-strength alloy of composition Fe_(30)Ni_(20)Mn_(25)Al_(25) (at.percent) are described in this paper. The as-cast alloy consisted of a periodic two-phase microstructure of interconnected, ~50-nm-wide rods with fully coherent {100} interfaces, strongly suggestive of formation by a B2 to [(B2 + body-centered cubic (bcc)) spinodal decomposition. The (Ni, Al)-rich B2 and (Fe, Mn)-rich bcc phases differed in lattice parameter by <0.5 percent. Hardness and yield strength of the as-cast alloy were found to be approximately 500 VPN and 1500 MPa, respectively, and increased by more than 50 percent after annealing at 550 deg C for several days. (Fe, Mn)-rich precipitates with a (3-Mn structure were observed in the annealed material.
