Abstract
A process for producing a particle-reinforced titanium alloy includes the steps of: heating a titanium alloy in which ceramic particles having a thermodynamically stable property are dispersed in a temperature range of not less than β-transus temperature; and cooling the titanium alloy to pass through the β-transus temperature at a cooling rate of 0.1-30° C./second. The process can further include, before the heating step, the step of compressing the titanium alloy in a two phase temperature range of α+β thereof or in a temperature range of not less than β-transus temperature.
