    40Cr is a kind of steel that is often used for semiaxis in heavy duty trucks, therefore high impact property of 40Cr steel is requested to adjust the heavy-duty machines working environment. In this study, the samples of 40Cr steel were heated under normal tempering temperature and quenched in air, water and oil, respectively. The experiments were carried out through charpy impact and experimental and simulation studies on temperature field of 40cr

  15. Simulation Analysis on Flow Field and Temperature

    simulation studies have been done on the flow field and temperature field in the mould. Mills et al. [4] showed that the centre of the narrow face shell at the mould outlet is the thinnest and increases from the centre to both sides gradually. The growth of the wide face solidification shell is influenced faintly by stream impact; hence, it is more
