Implication

Experimental study demonstrates superior abrasive wear resistance in martensitic and lower bainitic cast steels, indicating wear resistance depends on microstructural features beyond hardness.

Key Points

To evaluate how different martensitic and bainitic microstructural fractions influence the abrasive wear resistance of alloy cast steels microalloyed with boron and vanadium.
Two cast steel compositions were subjected to different heat treatments to produce distinct martensitic and bainitic microstructures, characterized via light, scanning electron, and transmission electron microscopy.
Three-body abrasive wear tests were performed using a T-07 tribotester according to ASTM G65-16 principles under a 44 N load with loose electrocorundum abrasive, analyzed via principal component and cluster analysis.
Martensitic microstructures achieved significantly higher abrasive wear resistance than bainitic microstructures, as upper bainite reduced hardness and promoted micro-cutting and micro-ploughing wear.
Lower bainite produced via austempering demonstrated wear resistance comparable to or exceeding that of tempered martensite despite lower bulk hardness, while vanadium additions showed no significant effect.
