摘要: Finely divided molybdenum particles were dispersed in aluminum oxide to serve as inclusions for the inhibition of grain growth and secondary recrystallization during sintering. Conventional powder metallurgy techniques used fabricate compacts containing up 16 vol% molybdenum. Three methods developing a uniform dispersion are compared on basis resulting microstructures. Specimens sintered vacuum had densities approaching 98% theoretical density with an average size 2μ or less no evidence recrystallization. The refinement is reflected transverse rupture strength data strengths exceeding 80 kpsi maximum 100 kpsi.
