摘要

A method for improving the microstructure of consolidated titanium alloy metal matrix composites which comprises the steps of P P(a) heating the composite to a temperature in the range of 800. degree. to 2000° F., the temperature being below the temperature at which interfacial reactions occur between the metal matrix and the fiber, and diffusing hydrogen into the composite to achieve a hydrogen level of about 0.50 to 1.50 weight percent;PP(b) altering the temperature of the composite to a transformation temperature at or near the temperature of transformation of (HCP) alpha in the hydrogenated composite to (BCC) beta;PP(c) cooling the composite to room temperature;PP(d) heating the thus-cooled composite to a temperature below the transformation temperature, and diffusing hydrogen out from the composite; andPP(e) cooling the composite to room temperature.

（b）将复合物的温度改变为等于或接近氢化复合物中的（HCC）α转变为（BCC）β的转变温度的转变温度;（P）

（c）将复合物冷却至室温;（P）

（d）将如此冷却的复合材料加热到低于转变温度的温度，并从复合材料中扩散出氢; （e）将复合材料冷却至室温。展开▼
