What is the effect of slow and fast cooling on the size of crystals

Webb24 juni 2024 · The cooling rates, namely 50 and 70 °C/s, were employed for this study. The steel plates were then cooled slowly to room temperature in a furnace to simulate the nonisothermal partitioning, similar to the hot-rolled coil cooling. WebbThe cooling rate of the steel has to be sufficiently slow so as to not let the austenite transform into bainite or martensite, but rather have it completely transform to pearlite and ferrite or cementite. This means that steels that are very hardenable (i.e. tend to form martensite under moderately low cooling rates) have to be furnace cooled. importing contacts into iphone https://fatfiremedia.com
