The Time-Temperature-Transformation Curve - Gear
WebMartensite is a very hard metastable structure with a body-centered tetragonal (BCT) crystal structure. Martensite is formed in steels when the cooling rate from austenite is at such a high rate that carbon atoms do not have time to diffuse out of the crystal structure in large enough quantities to form cementite (Fe 3 C). Therefore, it is a product of diffusionless … Web2. As retained austenite may transform to lower bainite, or to martensite, there takes place increase in dimensions of the part. Not only it creates problems in precision gauges, or dies, the neighbouring parts may be put under stress by it. In the component itself, stresses may be created to cause distortion, or cracking.
