MATERIAL - TITANIUM - COMMERCIALLY PURE, TI 6AL4V, TI 5AL-2-1/2 SN. STATIC AND FATIGUE STRENGTH OF DISSIMILAR ALLOY SPOTWELDS

Abstract

Three spotwelded, lap seam combinations comprised of (1) 0.025 in. thick Ti 6Al-4V and 0.025 in. thick commercially pure Ti; (2) 0.025 in. thick Ti 5Al-2.5 Sn and 0.025 in. thick commercially pure Ti; and, (3) 0.025 in. thick Ti 6Al-4V and 0.025 in. thick Ti 5Al-2.5 Sn were tension-shear, cross-tension and fatigue tested. The average tension - shear strengths of combinations (1), (2) and (3) were 908, 955 and 959 lb/spot, respectively, and the average cross- tension strengths were 302, 236 and 275 lb/spot, respectively. The respective tension-shear crosstension ratios were 0.33, 0.25, and 0.29. The fatigue strengths for 10 to the 7th power cycles life were 53, 86 and 97 lb/spot, respectively.
