摘要
Electro-discharge craters and re-cast materials are observed in the wire electro-discharge machining (WEDM) surface of Fe-30Mn-6Si and Fe-30Mn-6Si-5Cr shape memory alloys. The re-cast layer consists of the γ-austenite, Cu0.83Si0.17 compound, η'-(Cu, Si) and (Fe, Cr) solid solutions, and Zn phase. The WEDM Fe-30Mn-6Si and Fe-30Mn-6Si-5Cr SMAs still exhibit a good shape recovery, but a slight degradation of shape recovery occurs due to the depression of the re-cast layer. © 2004 Elsevier B.V.
