Abstract Low-temperature carburizing dramatically enhances the inherently low wear resistance of austenitic stainless steels due to formation a carbon-supersaturated solid solution, i.e. expanded austenite. The austenite from low-temperature has been intensively investigated. However, influence chemical composition steel on response not received same interest. This contribution addresses effect...

The relation between microstructure and creep property of austenitic heat-resistant cast steels with without Nb addition under the condition repeated vacuum carburizing quenching was investigated. Cr-carbide scale is formed on sample surface by a reaction, resulting in depletion Cr matrix adjacent to scale. A carburized layer consisting various fine carbides observed below Cr-depleted layer, de...

The carbon supersaturated SKD11 punch and core-die were prepared by the plasma carburizing at 673 K for 14.4 ks. upsetting experiment was performed using this to describe plastic flow of pure titanium β-titanium works in higher reduction thickness than 50%. measured load – stroke relationship utilized frictional behavior on contact interface work materials their hardening process. analyzed inve...

In this study carburizing and boronizing processes were applied to powder metallurgy steel specimens and the mechanical and tribological properties of the substrate and coatings were evaluated under various process conditions. The specimens, made from industrial test pieces, were carburized in a powder pack for a duration of 2-5 hrs at 850-950 ˚C. Similar specimens were pack boronized for 4 hr...

Heat treatment is one of the essential technologies in industrial manufacturing, and carburization processes heat-treatment technology. With increase technological requirements production, optimization carburizing technology desired. However, most mechanism models are derived from material properties related physical principles, which involved huge amounts parameters. Some parameters (such as d...
