All of the additive 15-5PH material was deposited with the parameters outlined in Table 2.The laser power was decreased by 200 W per deposited layer until the laser power was 1000 W, where it was held constant until the build was complete. The parameters on Table 2 were optimised for the specific powder distributions running a …
Technical Data Sheet. Alloy 15-5 is a precipitation hardening alloy exhibiting high strength and hardness with moderate corrosion resistance. Alloy 15-5 is a variant of the older 17-4 and 15-5 was designed to have greater toughness than S17400, especially in the through-thickness (short transverse) direction. Alloy 15-5 is used in applications
