In-situ diffraction studies of rate dependence of twinning, phase transformation, and slip in shape memory alloys
MetadataShow full item record
Many advanced materials show strong rate-dependence in their responses, even at time scales considered to be quasi-static. This is especially true for shape memory alloys. While theory is well established for rate dependence in cubic metals due to slip, few attempts have been made to develop similar theories for twinning and phase transformation, and their coupling with slip in low symmetry structures. This absence is largely because little is known about rate dependence in lower symmetry alloys. Toward filling this gap, classical phenomenological formulations of strain-rate sensitivity developed ...
