| Abstract Scope |
LPBF processes are well known for causing defects during the processing, which usually have a minor impact on the tensile strength but can have a detrimental impact on the fatigue properties. For this project we will compare the mechanical properties between wrought and LPBF samples of 17-4 PH. Rods of wrought 17-4 were machined into tensile and rotating beam fatigue samples, and cylinders were fabricated in the X, Y, and Z directions using an EOS M290, and machined into tensile and rotating beam fatigue samples. For the tensile strength, an ATS 1620C load frame was used with a 20,000 lb load cell. For the fatigue testing, a rotating beam fatigue testing set-up was used in four-point-bending configuration at 650 rpm. The results show very little differences when comparing the UTS but the results from the rotating beam fatigue tests show stark differences. |
