Abstract
This study characterized the mechanical properties of Stainless Steel PH1 (SS PH1) alloy product fabricated by Direct Metal Laser Sintering (DMLS) technique. The use of DMLS for medical, aerospace and automotive is attracting increasing interest due to the ability to control the stiffness of the device in the desired model. SS PH1 alloy has excellent mechanical and material properties to meet the desired character of the products in the applications mentioned above. In this research tensile test, elemental analysis and surface characterization have been performed on the samples of SS PH1 manufactured by DMLS process. The tensile properties have been tested with and without heat treatment of the tensile specimens. Energy Dispersive X-Ray Spectroscopy evaluates the elemental analyses (chemical characterization) in some areas. Surface morphology is characterized on the samples produced in different energy densities. Scanning Electron Microscope is used to analyse the fracture zone of the tensile specimens after the tensile test, micro cracks, and surface morphology. The results suggest possible innovative applications of the SS PH1 product in aerospace, automotive and biomedical implantation such as bone and dental application which can produce by DMLS process.
