TRIP-assisted C-Si-Mn steels are usually subjected to austempering with a preliminary intercritical annealing that is targeted at the multi-phase structure 40–60 vol.% of proeutectoid ferrite. The kinetics and mechanism phase-structural transformations can be impacted due additional alloying steel by strong carbide forming elements, thus necessitating an alternative approach for selection param...

The influence of the austempering temperatures on microstructure and mechanical properties austempered ductile cast iron (ADI) was investigated. ADI is nodular graphite iron, which owing to higher strength elongation, exceeds conventional spheroidal iron. Such a combination achieved by heat treatment through austenitization, followed at different temperatures. austenitization conditions were sa...
