Effect of Thermo-mechanical Processing Parameters on Phase Transformation and Hardness of Dual Matrix Ductile Iron

Mostrar todas las versiones(2)

The microstructural changes and hardness exhibited by ductile iron with dual matrix structure (DMS) are investigated. In particular, DMS microstructures are obtained by continuous cooling in the (ferrite + austenite) region followed by quenching to transform the austenite into martensite or by auste...
