This article presents the data demonstrating the synergistic effect of surface roughness and heat treatment on the fatigue behavior of 17-4 PH stainless steel (SS) fabricated via laser beam powder bed fusion (LB-PBF) [1]. Two sets of specimens, in as-built and machined surface conditions, were heat treated using five different recommended procedures for 17-4 PH SS by ASTM A693. Axial fully-reversed fatigue tests (R = -1) were conducted on heat treated as-built and machined specimens. The stable hysteresis stress-strain data, as well as the maximum and minimum stress and strain values for the cycle in a log10 increment are included for all conducted fatigue experiments. In addition, fractography images are provided for selected set of specimens.
本文展示了数据，证明了表面粗糙度和热处理对通过激光粉末床熔融（LB-PBF）制造的17-4 PH不锈钢（SS）疲劳行为的协同作用[1]。两组试样，一组为成型态表面，另一组为加工态表面，按照ASTM A693推荐的五种不同工艺对17-4 PH SS进行热处理。对热处理后的成型态和加工态试样进行轴向全反向疲劳试验（R = -1）。所有进行的疲劳试验都包括稳定的滞后应力-应变数据，以及以log10增量表示的循环中的最大和最小应力及应变值。此外，还提供了所选试样组的断口图像。
