摘要
Fatigue test results are provided for hot-deformed powder steels with microadditions of Na, Ca, and Al. Microalloying promotes improvement of joining between particles and makes fatigue crack development difficult in its stable consolidation stage, and also during accelerated failure, which provides an improvement in fatigue strength properties compared with reference specimens.
