Influence of Alfa’ Martensite on Shape Memory in Fe-Mn-Based Alloys

چکیده
An Fe-16MndSi alloy exhibits a good one-way and a little two-way shape memories by the stress induced y + E martensitic transformation and its reversion on heating and cyclic thermal y 2 E transformations, respectively. An intrusion of small amount of a' martensite at the initial shape change is not found to deteriorate the one-way memory and rather enhance the two-way memory. The two Fe-Mn-C alloys are also examined and their inferior shape memory is considered not due to the influence of a' martensite.

A jumping shape memory alloy under heat
Shape memory alloys are typical temperature-sensitive metallic functional materials due to superelasticity and shape recovery characteristics. The conventional shape memory effect involves the formation and deformation of thermally induced martensite and its reverse transformation. The shape recovery process usually takes place over a temperature range, showing relatively low temperature-sensit...

متن کاملTransformation Behavior and its Effect on Damping Capacity in Fe-Mn Based Alloys
7 -+ E transformation behavior in a Fe-21Mn alloy with different grain size and a Fe-32Mn-6Si alloy with various degrees of wld rolling is investigated and correlated with damping capacity. Effect of microstructure on damping capacity is discussed on the assumption that the capacity is proportional to volume swept by 7 / e boundaries. 1.INTRODUCTION Fe-Mn based alloys have been well known for s...
