摘要
The shape memory properties and microstructure associated with gamma(fcc) -->, epsilon(hcp) martensitic transformation in an Fe-14Ru alloy hare been investigated. The degree of shape recovery was measured via a bending lest, and the microstructure was examined using X-ray diffractometry optical microscopy, and transmission electron microscopy. The Fe-14Ru alloy showed shape recovery to some ex-tent, but to a lower degree than in Fe-Mn-Si based shape memory alloys. The lower strength of the matrix, the presence of epsilon and alpha' martensites at room temperature, and the higher stacking fruit energy in the Fe-14Ru alloy are thought to be responsible for the weaker shape memory effect.
