Abstract: 
The goal of this study was to develop nano/ultrafine bainitic microstructure in AISI 52100 steel. For this purpose, the specimens were austenitized, followed by austempering treatment at different temperatures and times. Austempered samples were characterized using field emission scanning electron microscopy, X-ray diffraction and tension and wear tests. The results showed, at austempering temperature up to 250oC, the strength and ductility reached 2000 MPa and 7%, respectively. By further increasing the austempering temperature, the strength and ductility were simultaneously reduced (to about 1808MPa and 3%).
