INVESTIGATION OF PHYSICAL AND MECHANICAL PROPERTIES OF Ti ALLOY (Ti-6Al-4V) UNDER PRECISELY CONTROLLED HEAT TREATMENT PROCESSES

Titanium and titanium alloys are metals that contain a mixture of titanium and other chemical elements. Such alloys have very high tensile strength and toughness. They are light in weight, have extraordinary corrosion resistance and ability to withstand extreme temperatures. Its applications include military applications, medical devices, connecting rods on expensive sports cars and consumer electronics. Titanium and Titanium Alloys are heat treated in order to reduce residual stresses developed during fabrication (stress relieving), produce an optimum combination of ductility, machinability, and dimensional and structural stability (annealing) increase strength (solution treating and aging), optimize special properties such as fracture toughness, fatigue strength, and high-temperature creep strength.
