Effect of Heating Temperature on the Grain Size and Titanium Solid-Solution of Titanium Microalloyed Steels
Abstract: Through studying on the heating process of titanium microalloyed steels, the influence of heating temperature on the austenite grain size and the solid dissolution, precipitation law of Ti microalloying element were analyzed, and the results showed that, the austenite grain size increased with the increase of heating temperature, When the heating temperature reached 1050°C and 1250°C, the austenite grains appeared the obvious coarsening process twice. TiC particles dissolved gradually as the heating temperature increased. When the heating temperature rose to 1100°C, TiC particles disappeared basically, When the heating temperature rose to 1250°C, TiN particles began to be dissolved and grow up.
