High pressure hydrogen storage vessels are frequently retired upon reaching their designed number of pressure cycles, even in cases where the in-use pressure cycles are significantly less severe than the design pressure cycle. One method for extendin

SMST 2022: Extended Abstracts from the International Conference on Shape Memory and Superelastic Technologies.
In this work, a new method of processing shape memory alloys was utilized to understand the effects of disrupting the martensitic long range order and forming amorphous nanodomains with martensitic short range order. Based on the obtained results, st
