| Abstract: | An effectual method that can determinate the surface heat-transfer coefficients was given by means of the solution of the inverse problem of the heat conduction for steel 45 cylinder with phase transformation during quenching. The technique is composed of numerical methods and determination of the relationship between time and temperature,and suited for various quenchants. It can avoid the considerable discrepancies in the obtained value due to small variation in the experimental condition.In the numerical calculation, the thermal physical properties of materials were treated as the functions of temperature and the volume fraction of consituent of phase transformation. |
