Effect of deformation and grain size on austenite decomposition during quenching and partitioning of (high) silicon?aluminum steels
نویسندگان
چکیده
The effect of austenite deformation on carbon partitioning and transformation to athermal isothermal martensite, bainite during quenching (QP) is described for three steel compositions: Fe-0.3C-0.6Si-1.1Al, Fe-0.3C-1.0Si Fe-0.3C-0.5Si-0.5Al. Microstructures were characterized using SEM-EBSD, TEM XRD. Austenite decomposition kinetics was investigated dilatometry. Deformation close the no-recrystallization temperature refines grain size, lowers martensite start affects stability QP processing. results in respect dilatation measurements retained contents at room corroborate microstructures their hardness can help designing optimal treatments these novel steels.

Influence of Boron on Initial Austenite Grain Size and Hot Deformation Behavior of Boron Microalloyed Steels
The initial austenite grain size of boron microalloyed steel with three different amounts of boron (20, 40, and 60 ppm) was investigated under different heating temperatures (1150, 1100, and 1050 °C), and hot compression tests of samples in a wide range of temperature (900–1100 °C) and strain rate (0.1–10 s−1) were conducted. It was found that the initial austenite grain size increases with inc...
