Before And After

It is well known that austempered spheroidal graphite cast iron shows good tensile and elongation. And, retained austenite include in the austempered spheroidal graphite cast iron structure was known to effect for the mechanical properties when TRIP was occurred. On the other hand, fineness and homogeneity of the structure are considered to influence as a factor to improve mechanical property. In this study, the mechanical properties of spherical graphite cast iron was evaluated that it treatmented fineness prior-structure and austenitized at (α + γ) range followed by isothermal treatment at bainitic transformation temperature range. Compared the heat treatment of this study and typical austempering treatment, the mechanical properties with good balance of strength and ductility were obtained in the heat treatment of this study. But, retained austenite that it determined by x-ray diffraction was slightly changed before and after the tensile test. Therfore, it was considered that not TRIP but complex phase effect on mechanical properties.

Spheroidal graphite cast iron is a material with a wide range of uses such as in automobile parts. By applying active screen plasma nitriding (ASPN) treatment, the use of spheroidal graphite cast iron is expanded, and it can be expected to be used under special load conditions. In this study, we evaluated the effect of ASPN treatment on the mechanical properties of spheroidal graphite cast iron. With ASPN treatment, a nitride layer was formed on the sample surface and a diffusion layer was formed further inside the nitride layer. The thickness of nitride layer increased as the treatment temperature increased. The hardness was improved by ASPN treatment. The abrasion resistance was improved by ASPN treatment, and longer treatment time resulted in higher abrasion resistance. The fatigue strength was improved by ASPN treatment, and longer treatment time resulted in higher fatigue strength. ASPN treatment also improved the corrosion resistance.
