The effect of low-alloy additions on low-C steels hardenability is reported. Various as-quenched materials with microstruc- tures consisting of low-C (granular) bainitic (B), mixed bainitic (B)/martensitic (M) and fully martensitic microstructures were produced. Results show that for a given cooling rate, an increase of austenite grain size (AGS) and of Mo and Cr contents decreases the transformation temperatures and promotes martensite formation.

Abstract
The effect of low-alloy additions on low-C steels hardenability is reported. Various as-quenched materials with microstruc- tures consisting of low-C (granular) bainitic (B), mixed bainitic (B)/martensitic (M) and fully martensitic microstructures were produced. Results show that for a given cooling rate, an increase of austenite grain size (AGS) and of Mo and Cr contents decreases the transformation temperatures and promotes martensite formation.File in questo prodotto:
