Crack propagation mechanisms of an aged nickel-titanium-hafnium shape memory alloy

Mechanisms of crack propagation in a NiTiHf sample were studied from post-mortem microstructure characterizations about cracks. Transmission electron microscopy (TEM) analysis showed that a crack propagated within a martensite band along 〈011〉 type II twin planes. The crack was observed to switch be...
