and partitioning is a novel heat treatment that has been proposed
to give a good mixture of tensile strength and the total elongation by producing
martensitic steel containing a certain amount of retained austenite ( The
2 step Q&P process enhances the stabilization of austenite by carbon
enrichment through the segregation of the carbon from martensite to RA The
microstructure was investigated using LOM, SEM, EBSD, and XRD The X ray
diffraction has been carried out in order to assess the retained austenite
(RA volume fraction It showed convergent RA fractions for different heat
treatments with different quenching and partitioning temperatures However,
for different holding time in quenching and partitioning steps, recognizable
differences in RA can be observed The mechanical properties obtained by
Q&P reported for 20 CMnSi steel at different Q&P temperatures showed
comparable results While, at different Q&P holding time, observable change
in the mechanical properties is reported
