Abstract
A Ni-Ti compact underwent an exothermic fusion reaction during quick heating in a vacuum pressure. Consequently. the phenomena resulted in the purification of the alloy. The application of this technology will simplify the manufacturing process and facilitate quality control of the product. The authors researched the effect of heating rates. vacuum range and gaseous atmosphere on the exothermic fusion reaction in detail. and arrived at the optimum conditions for the reaction. Moreover. porous semi-fused Ti-Ni alloy was produced by the exothermic reaction, under vacuum conditions in a closed silica tube.
The Ti-Ni alloys obtained by the exothermic reaction showed mechanical properties comparable with a commercial alloy.
