The Methods of Preparation of TiNiX Alloys and Their Forming. By Radim Kocich Ivo Surman and Miroslav Kursa. The NiTi alloy was prepared from elementary powders in a planetary ball mill under atmosphere of Ar. During sintering of Ni and Ti a significantly exothermic reaction takes place so that the heat generated during the process is
202059Nanoparticles are materials that are confined to the nanoscale in all three dimensions. Engineered nanoparticles play an important role in nanotechnology. The specific properties of nanoparticles is defined by particle sie chemical composition crystallinity and shape. During production these can be controlled by temperature pHvalue concentration chemical composition surface
