Abstract

Molybdenum disilicide (MoSi₂), due to its high melting point and oxidation resistance, is a candidate for high temperature structural applications. However, its high temperature creep resistance and ambient temperature fracture toughness need to be significantly improved to enable applicability. This study examines the effects of feedstock purity and processing on the resulting microstructure and properties of MoSi₂. Processed MoSi₂ samples were obtained from several laboratories in order to determine the effects of purity and processing. The samples were characterized for their microstructure, hardness, and oxidation. The results indicate that grain size and volume distribution of SiO₂ particles influence the mechanical properties.
