Studies were continued to obtain a better understanding of the physical metallurgy of the aging reaction of B 120 VCA Ti alloy sheet to establish an optimum heat treatment. The loss of ductility of the weld metal when aged to relatively low strength levels is another area of concern as well as the effects of filler metal composition, the cold roll and duplex age sequence, grain refining treatments cold roll and solution treat at about 1200 for 2 to 10 hr, and the transformation behavior of the base and weld metals. Welds in the as-received base material prior to aging are being cold rolled to reductions of 10 and 25. Elastic modulus determinations will be made on base metals and weld metals subjected to various heat treatments.
