Improving strength and ductility of low activation martensitic (LAM) steel by alloying with titanium and tempering

In sequel to our previous study (Mater. Sci. Eng. A, 769 (2020) 138,471), we elucidate here the determining role of alloying with Ti and tempering effect on tensile and creep properties in low activation martensitic steel (LAM) and compare with the coarse-grained (CG) LAM steel. When the tempering temperature was decreased from 760 °C to 730 °C, while maintaining time constant at 30 min, grain size and MX carbide density was constant at ~7.0 ±...
