Bainite vs Martensite

Jul 09, 2018The figures below have some variation in how they represent wear resistance; however, in all cases higher hardness means better wear resistance, so that is the key to interpreting them. Conclusion and Summary. Tempered martensite and lower bainite are very similar in that they are both lath-like microstructures with small carbides within. Get price
