| 英文摘要 | Residual stress is a ubiquitous phenomenon in laser powder bed fusion (LPBF) metal parts due to high temperature gradients and uneven heating during building processes. Subsequent stress-relief (SR) heat treatment is usually conducted to reduce the geometrical distortion and microscopic cracks induced by residual stress after the LPBF process. Using electron microscopy, X-ray diffraction, and stress-rupture tests, the experimental results revealed that the stress-rupture life of a nickel-based superalloy, IN625 alloy, subjected to SR treatment at 870 degrees C and 980 degrees C is inferior to that of the as-built (AB) alloy. The fundamental cause for this phenomenon is that more delta phase precipitates in the grains of the AB alloy during the stress-rupture test at 750 degrees C/230 MPa, resulting in an increased dispersion hardening effect and a decreased ductility. Furthermore, the Laves and delta phases along grain boundaries in the SR treated alloys are more likely to coarsen, which is the second reason for the decreased stress-rupture life of the SR treated alloys. |
