Effect of austenitising and deformation temperatures on dynamic recrystallisation in Nb-Ti microalloyed steel
An investigation into influence of the austenitising temperature and the austenite deformation temperature on Nb precipitation and recrystallisation kinetics was carried out for a steel containing 0.081C-0.021Ti-0.064Nb (wt. %). The austenite grain structure was correlated to the dispersive properties of Nb atom clustering and precipitation. Irrespective of the austenitising temperature, deform...
متن کاملEffect of solidification rate on microstructure evolution in dual phase microalloyed steel
In steels the dependence of ambient temperature microstructure and mechanical properties on solidification rate is not well reported. In this work we investigate the microstructure and hardness evolution for a low C low Mn NbTi-microalloyed steel solidified in the cooling rate range of 1-50 Cs-1. The maximum strength was obtained at the intermediate solidification rate of 30 Cs-1. This result h...
متن کاملEquilibrium Model of Precipitation in Microalloyed Steels
The formation of precipitates during thermal processing of microalloyed steels greatly influences their mechanical properties. Precipitation behavior varies with steel composition and temperature history and can lead to beneficial grain refinement or detrimental transverse surface cracks. This work presents an efficient computational model of equilibrium precipitation of oxides, sulfides, nitri...

متن کاملti - microalloyed steel, quenched from hot forging temperature
the aim of the paper presented here is to develop the ti - micralloyed steel in otrer to oprtmize the mechanical properties after direct quenching from hot forging temperature. for this purpose, seven melts containing various amounts of titanium were prepared and cast in metal and sand molds. from the ingots, cast in metal mould, tractor links were produced by hot forging. the produced links we...
