What does this research mean for the field?

A non-recrystallization heat treatment at 900 °C for 1 hour increases the creep rupture time and creep ductility of laser powder bed fusion-produced stainless steel 316L, surpassing the ductility of hot-rolled benchmarks due to enhanced deformation capacity during tertiary creep. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Implication

Randomized trial investigates creep properties in stainless steel 316L, suggesting enhanced performance with heat treatment.

Key Points

This research aims to evaluate the influence of heat treatment on the creep properties and microstructure of stainless steel 316L produced by laser powder bed fusion.
Non-recrystallization heat treatment at 900 °C for 1 h was applied to stainless steel 316L variants previously treated at 450 °C for 4 h.
Creep tests conducted at 600 °C and 225 MPa until rupture and minimum creep rate were performed.
Microstructure characterized using XCT, SEM, EBSD, TEM, and tensile tests on miniaturized specimens.
Heat treatment increased creep rupture time, minimum creep rate, and creep ductility compared to the 450 °C / 4 h condition.
Creep ductility exceeded that of a hot-rolled 316L benchmark variant.
Reduction in volume fraction of microcracks in the 900 °C / 1 h treated condition linked to enhanced deformation capacity.
