| dc.description.abstract | This study investigates and compares the influence of different heat treatments and holding time on the microstructural and mechanical property (hardness) of SLM MS300 steel and conventionally produced MS350 steel. The microstructure and hardness were investigated after applying solution heat treatment at 920 oC for 1 hour plus aging at 510 oC for 1 hour, 4 hours, and 12 hours holding time, and direct aging at 510 oC for 1 hour, 4 hours, and 12 hours holding time. Both SLM MS300 and MS350 reached their peak hardness after applying solution heat treatment at 920 oC for 1 hour plus aging at 510 oC for 4 hours. MS350 reaches ca. 17% higher hardness compared to SLM MS300 (715 HV for MS350, 611HV for SLM MS300). SLM MS300 obtain the same microstructure (columnar and equiaxed dendrite) after applying direct aging at 510 oC as untreated, but the structure becomes more blurry with a long time of aging. While after the solution heat-treated at 920 oC for 1 hour, the microstructure changed to a coarse lath martensitic structure. | |
