DOI: 10.1007/s13369-018-3217-z
Abstract: The relationship between the microhardness and the loading transformation stress of superelastic NiTi is investigated at room temperature. Superelastic NiTi shows a loading stress plateau under mechanical loading due to austenite-to-martensite microstructural phase transformation. The… read more here.

DOI: 10.1088/1361-665x/aa721b
Abstract: The undesirable effects of hydrogen show significant alterations to the thermomechanical behavior of superelastic NiTi shape memory alloys. Through experimental results, the presence of hydrogen induces a delay of forward transformation. Added to that, hydrogen-induced… read more here.
