The metabolic way of calcium ions which was released due to in vivo degradation of porous β-TCP ceram ics was studied by using the radioisotope 45 Ca as tracer
The thermal shape-memory effect at room temperature for Co-32% Ni(mass fraction) magnetic shape memory alloy of single crystal was presented. When compressing t
By adopting an equivalent geometry model of machining process and considering thermo-plastic properties of the work material, a finite element method(FEM) to st
