Abstract:

        The residual austenite has significant influence on the mechanical properties of Dual Phase Austempered Ductile Iron (ADI). We address the effects of austenitizing temperature on the content of retained austenite in ADI with X-ray method to investigate the relationship between process, organization and performance. Results show that the content of retained austenite gradually increases with the increase of austenitizing temperature.

Key words: austempering, ADI, austenite, mechanical property
