Microstructural and mechanical properties of low-carbon ultra-fine bainitic steel produced by multi-step austempering process

The multi-step isothermal austempering heat treatment to achieve an ultra-fine bainitic microstructure and maximum volume fraction of bainite was conducted on a steel containing 0.26 wt% carbon. The microstructural and crystallographic characteristics, as well as the mechanical properties and fractu...
