Metal matrix composite and process for producing the same |
摘要 |
<p>A metal matrix composite comprising 2 to 80 volume % of alpha -alumina powder as a reinforcement, said alpha -alumina powder comprising polyhedral primary particles substantially having no fracture surface, D50 of the alpha -alumina powder being 0.1 mu m to 50 mu m and a ratio of D50 to D10 of the alpha -alumina powder being not more than 2, wherein D10 and D50 are respectively particle sizes at 10% and 50% cumulation from the smallest particle side of a weight cumulative particle size distribution and a process for producing the metal matrix composite which comprises infiltrating a molten metal into an alpha -alumina powder optionally under pressure.</p> |
