Microsturctural Characteristics and Mechanical Properties of Ti 6Al 4V Alloy in Additive Manufacturing

Abstract

Additive manufacturing (AM) is a technique used to create sophisticated tools. This research employs selective laser melting to produce Ti-6Al-4V alloy, followed by after-production heating processes to minimize thermal stress and enhance its mechanical characteristics and microstructure. The study investigates the microstructure, mechanical characterization methodologies, SSRT and SCC advancements, titanium alloy corrosion characteristics, and additive manufacturing of Ti-6Al-4V alloy. This study investigates the mechanical and physical characteristics of additively manufactured Ti-6Al-4V alloy samples, which include tensile strength, elongation, relative density, microhardness, and Young's modulus. This specimen's stress corrosion cracking (SCC) has been assessed using a gradual strain rate test in air and aqueous sodium chloride solutions. The study also examined the effect of thermal processing on the corrosion rates of the Ti-6Al-4V alloy sample produced by the powder bed technique. In phosphate buffer electrolytes and NaCl, corrosion tests were carried out, and the results were compared.
