Abstract

Abstract

The thermal response experiments of TA15 Ti alloy and LY12 Al alloy irradiated by CW laser in supersonic flow or natural convection conditions were done, temperature history curves and perforation time were obtained. The results show that the flow effect is cooling before the material is melted, it is denudation effect while the material is melting, it is helpful of accelerating the material ablation and perforation. The tangential air flow can have an effect on the temperature distribution of TA15 Ti alloy, but no effect on Al alloy.
