Abstract
Abstract: Selective laser melting (SLM) is an advanced additive manufacturing (AM) technique which constructs 3D objects by melting powder materials in a laser, layer by layer, according to a computer-aided design (CAD) model. SLM is utilized to create products from a variety of materials, with qualities equivalent to benchmarked conventionally manufactured components. Because of these qualities, 17-4PH stainless steel is a suitable material for a diverse range of industrial applications, including structural parts in the aerospace, chemical and petrochemical sectors. The specimens using 17-4PH stainless steel powder were successfully manufactured by optimizing the parameters using SLM process. The as built specimens were heat treated using two different cooling rates. Present research paper evaluates and compares the microstructure, wear behavior and tensile strength of the finished additively manufactured specimens with as built, post heat treated and wrought specimens.
