INVESTIGATION OF HEAT TREATMENT AND WELDING CHARACTERISTICS OF B 120 VCA TITANIUM ALLOY SHEET, PART II
Abstract
Moduli of elasticity (as a function of aging time) meas rements are presented for heattreated and aged (900 F for zero to 160 hr) weld metal and base metal (B120 VCA Ti alloy). The curve for the isothermal aged base metal liesABOVE 16.3 X 10 TO THE 6TH POWER PSI FOR TIME IN EXCESS OF 20 HR. The curve for the weld metal parallels the base metal but is about 0.5 x 10 to the 6th power psi lower. Flash annealing at 1000 F for 20 and 40 min. reduced the moduli of both the base and weld metals. Welds were made with magnetic stirring and vibration techniques in attempt to refine the weld metal grain structure. Weldments were reduced 25% by cold rolling in a further study of welding and aging sequences. The microprobe analyzer has not measured any significant variation in the amounts of the principle constituent elements resulting from the application of magnetic stirring to the molten weld metal.
