Development of Oxynitride Materials for Ceramic Tool Bits.

摘要

SIALON ceramic compositions were prepared by hot pressing mixtures of silicon nitride, silica and aluminum nitride. Dense microstructures were obtained and X-ray diffraction analyses were performed. Transverse bend strength measurements were performed at room temperature and 1300 C for the various compositions. Cutting tool evaluation tests were performed against hardened tool steel, cast iron and a specialty alloy Rene 41. (Author)
