Abstract

ZrO₂-coated NiAl powders have been elaborated using an innovative mill process, the so-called mechanofusion process. Following processing conditions, different types of particles (size, morphology, degree of coating) can be obtained. These powders were consolidated to full density by HIPping and mechanical tests were carried out on the various elaborated products at temperatures ranging between 20-800°C. Results are compared to those previously obtained for ZrO₂/NiAl composites elaborated by conventional methods. It is shown that mechanical strength of ZrO₂/NiAl composites can be considerably improved by using the mechanofusion process.
