EXPERIMENTAL INVESTIGATION ON HEAT TREATED TI-6Al-4V WELDED JOINTS BASED ON TRIBOLOGICAL AND NON DESTRUCTIVE TECHNIQUES

Ti-6Al-4V (grade 5) It is a high strength-to-weight alpha-beta titanium alloy. It is one of the most widely used titanium alloys and is employed in a variety of low density applications There is need to study tribological properties of heat treated Ti-6Al-4V welded joints. Our project deals with the tribological properties (Corrosion, Wear), NDE tests (Radiography, Dye-Penetration, Ultrasonic Testing), Mechanical test (Tensile test) on Ti-6Al-4V(Grade-5) material welded joints. The corrosion test should be performed on base metal (before heat treated),annealed metal(after heat treated) and comparing these two for the best; The wear test will be performed on base metal of Ti- 6Al-4V, heat treated metal metal(annealed) and on welding region for welded joint of base metal before heat treated and the readings will be noted. The radiography test is to verify the internal structure of the body. The dye - penetration will be performed on Ti-6Al-4V welded joint for knowing the cracks developed on welded region. The tensile test will be performed on Ti-6Al-4V welded joint to know the mechanical property (Tensile). The ultrasonic test will be performed on Ti-6Al-4V welded joint
