Advances in the fabrication of titanium metal matrix composite

This paper describes recent developments in the processing of continuous fi bre reinforced titanium alloy metal matrix composite. Used selectively, MMC s can have a dramatic effect on performance and weight. They combine the ex ceptional strength and stiffness of a ceramic with the many advantages of a metal matrix. which include elevated temperature capability, impact resist ance, and environmental stability. Titanium MMCs have passed through the in itial material research stages and the basic mechanical performance criteri a are now well established. Further progress towards commercial exploitatio n now depends on detailed process definition and cost reduction. (C) 1999 E lsevier Science S.A. All rights reserved.
