Copper-titanium alloys in the range 1 to 5 wt% titanium can exhibit properties comparable to the well-known Cu-Be alloy series after suitable heat treatment. Age hardened Cu-Ti alloys represent a potentially important substitute for the conventional high-strength Cu-Be materials in a variety of applications, particularly in the electronics industry. In this paper the preliminary results of conventional electron microscopy (CTEM) and high-resolution electron microscopy (HREM) studies of the fine-scale structure of the mechanical twins which form in particle hardened copper-titanium alloys are reported.
