Mechanical properties of 17-4 PH steel manufactured by powder bed fusion

Abstract

The mechanical properties, such as the modulus of elasticity, yield strength, and ultimate tensile strength, were validated to precipitate-hardened 17-4PH stainless steel fabricated by the laser powder bed fusion process. Initially, six specimens were manufactured by varying the thickness and the fabrication angle, followed by tensile testing to obtain the modulus and yield strength. The results showed that the mechanical properties were low; therefore, further research is needed to change the manufacturing parameters to improve the mechanical properties
