Abstract | The resistance of metal films during laser rapid melting and solidification process (LRMSP) was measured with a transient resistance apparatus which is suitable for measuring between 0 and 500 Omega and the time response of nanosecond. The effects of laser power and preheating temperature on the measuring results were analyzed. The results show that the resistance of aluminum film was increased rapidly and then decreased with time, and the rate of resistance decreasing is slower than that of resistance increasing. The peak value of the measured curve as well as heating and cooling velocities increase with laser power increasing. With preheating temperature enhancing, the peak value also increase, but cooling velocity decreases, resulting from the decrease of heat conductivity of sample lower surface. When the heat-transfer capability of the undersurface of the sample is lower, there is a little increase in resistance peak value, but the change of resistance is slower in the cooling period. |
