Ultrafine-Grained Ti-13Nb-13Zr Alloy Produced by Severe Plastic Deformation [PDF]

Materials Research, 2017
Biomedical devices currently in use (prostheses, implants) have satisfactory performance in many cases. However, sometimes the body reacts to the device insertion and may lead to its rapid replacement. Some of these disadvantages can be solved by the use
