| Abstract: | ZL109 alloy matrix composites reinforced with aluminosilicate (Al 2O 3 SiO 2) fiber were fabricated by squeeze casting. The elevated temperature creep characteristics of composites and ZL109 alloy at different test temperatures and stresses were studied. It is shown that creep limiting stress of composites reinforced with fiber is 1.2 times as that of ZL109 alloy at 573K, and 4 times at 673K. But creep rupture of the composites, as compared with that of ZL109 alloy, is unexpected at high temperature. |
