On October 22, EWI (Edison Welding Institute) published a technical article stating directly that high-performance nickel alloy parts produced by LPBF do not automatically become service-ready simply because printing succeeded. Based on metallurgical research on two nickel-based alloys, IN625 and IN718, the article argues that post-processing strategies must be validated individually for each specific alloy, build condition, and application, and that simply applying wrought-material heat treatment schedules often fails. The article explains that the microstructure formed by rapid solidification, cyclic thermal exposure, elemental segregation, and residual stress responds to heat treatment very differently from that of wrought material. Stress relief and hot isostatic pressing (HIP) significantly alter the as-printed microstructure of LPBF IN625; the precipitation-hardening response of IN718 is highly sensitive to cooling rate, and cooling rate should be treated as a controlled heat-treatment variable. Alber Sadek, Principal Engineer at EWI, notes that alloy-specific post-processing strategies offer a more defensible certification path for LPBF nickel-based parts. This means that additive serial production of aerospace and energy components is moving from "print success" toward "service qualification," making heat treatment the missing link in unlocking the performance of nickel alloy LPBF. For powder buyers, the implications are: (1) when purchasing IN625/IN718 powder, require suppliers to provide heat-treatment window recommendations matched to particle size and oxygen content; (2) the spread of combined HIP plus aging processes will increase demand for nickel-based powders with low inclusion content and narrow particle size distribution; (3) include traceability clauses for heat-treatment schedules and powder batches in procurement contracts, and establish batch process records in advance to meet stringent certification requirements.
