文摘

•: Paper explores fatigue mechanisms of SLMed ALSi12 alloy in gigacycle fatigue.
•: Base plate heating controls the cooling rate and the corresponding properties.
•: Base plate heating improves the fatigue performance of SLM ALSi12 alloy.
•: Base plate heating also improves the fatigue crack propagation behavior.
•: Defect distribution dominates the microstructural effects on fatigue.
