Abstract

The research work focuses on a novel post-processing sequence to improve the surface integrity and residual stress characteristics of as-printed Inconel718 (IN718) samples. The as-printed IN718 samples are subjected to solution treatment at 1050 °C, two-step precipitation hardening (@ 720 °C for 8 h and @ 620 °C for 8 h), and low plasticity burnishing. Two different sequences were attempted. Sequence-1 involves solutionizing → low plasticity burnishing followed by precipitation hardening, and sequence-2 includes solutionizing → precipitation hardening followed by low plasticity burnishing. The experimental observations and detailed investigations revealed that the samples processed via sequence 2 exhibited a better surface finish. The microhardness of the samples of sequence 2 is 10% higher than their counterparts in sequence 1. The maximum residual stress of −1375.33 MPa is obtained in sequence 1 as compared to the residual stress of −1100.67 MPa in sequence 2. The influence of the processing sequences on the surface properties has been discussed in detail using the XRD and microstructural characterization supported with EBSD analysis.

低塑性烧结激光直接能量沉积合金 IN718 的表面特性
这项研究工作的重点是采用一种新颖的后处理程序来改善轧制 Inconel718 (IN718) 样品的表面完整性和残余应力特性。印模 IN718 样品在 1050 °C 下进行固溶处理、两步沉淀硬化(720 °C 8 小时和 620 °C 8 小时)和低塑性抛光。尝试了两种不同的顺序。顺序-1 包括固溶 → 低塑性抛光,然后沉淀硬化;顺序-2 包括固溶 → 沉淀硬化,然后低塑性抛光。实验观察和详细调查显示,通过序列 2 加工的样品具有更好的表面光洁度。序列 2 样品的显微硬度比序列 1 高 10%。序列 1 得到的最大残余应力为 -1375.33 兆帕,而序列 2 得到的残余应力为 -1100.67 兆帕。在 EBSD 分析的支持下,利用 XRD 和微结构表征详细讨论了加工顺序对表面特性的影响。
