Abstract Scope |
This study investigates the effect of post-manufacture heat treatments on the mechanical properties of 15-5 PH stainless steel (SS) fabricated by laser powder-directed energy deposition (LP-DED). Two different heat treatment procedures (CA-H900 and CA-H1150) were performed, and their influence on the microstructure was examined using the scanning electron microscope. Tensile tests were performed to evaluate the mechanical properties at cryogenic and room temperatures. The elongation at failure was significantly higher for specimens treated with CA-H1150 than those with CA-H900 at both testing temperatures. In contrast, the ultimate tensile and yield strengths of CA-H900 specimens were higher than CA-H1150 specimens. The fractography examinations reveal that the specimens treated with CA-H900 exhibited brittle behavior at cryogenic temperature. |
