| Abstract: | An analytic calculation method of material's temperature field is presented for pulse laser action when the laser-radiated object is regarded as homogeneous medium with constant thermophysical properties.Based on the study results and the model of martensite phase transformation,the method is employed to calculate the size of a hardened zone during the heat treatment of steel by the pulse laser.The feasibility of this method is also proved by experimental data. |

| Keywords: | pulse laser temperature field heat treatment analytic calculation. |
