Wide tuning the carbon supersaturation within Fe-C lath martensite via high pressure martensitic transformation of Fe-0.45C alloy

The carbon supersaturation within lath martensitic lattice was tuned via thermal treatment of a Fe-0.45C alloy under hydrostatic pressure of 1-6 GPa. The content of supersaturated carbon increases linearly with high pressure till 84.4% of the nominal carbon content under 6 GPa. The strengthening of carbon supersaturation is remained proportional to the square root of its content but the contribution was underestimated.

Automated summary

The carbon supersaturation within the lath martensitic lattice was adjusted by thermally treating a Fe-0.45C alloy under hydrostatic pressures of 1-6 GPa. The amount of supersaturated carbon increased linearly with high pressure, reaching up to 84.4% of the nominal carbon content under 6 GPa. The strengthening effect of carbon supersaturation remained proportional to the square root of its content, but the contribution was underestimated.
