Ambient temperature fracture strength of pure alumina

摘要: The fracture of alumina copper-vapor laser tubes has led to great interest in the mechanical properties pure ({alpha}-Al{sub 2}O{sub 3}) Copper Laser Program. In particular, knowledge strength used make these is required at temperatures ranging from ambient 1500{degree}C. purpose work reported here was confirm that data reasonably well describe behavior goal this investigation with minimum effort and cost. To end, only temperature tests were planned.
