Abstract: Abstract Ti-50.3Ni-0.7Ag (at.%) scaffolds were prepared by sintering of rapidly solidified alloy fibers. The sintered scaffolds possessed high porosity of 80% and large pores of 150–600 μm in size. The yield strength of the scaffold after… read more here.

DOI: 10.3390/met9030316
Abstract: In this work, we are interested in examining the strain rate effect on the mechanical behavior of Ni–Ti superelastic wires after hydrogen charging and ageing for 24 h. Specimens underwent 50 cycles of loading-unloading, reaching… read more here.
