OSTI ID:6467446
Additional high temperature mechanical property data were collected in this period. Samples were prepared by hot pressing at 1750/sup 0/C for various length of time to develop ..beta..-SIALON grains with different sizes and aspect ratios. The composition of ..beta..-SIALON containing 10 equivalent % of aluminum (designate as ..beta..-10) containing 2 and 10 wt % of garnet and ..beta..-10 containing 10 wt % of cordierite were prepared. Specimens were hot pressed at 1750/sup 0/C for one hour. Typical microstructure of these samples are shown. Size and aspect ratio of the ..beta..-SIALON grains in these samples are given. Temperature dependence of fracture strength and fracture toughness of these specimens were measured. The strength was measured by 4 point bending and toughness was measured by indentation bend.
