Effects of latent heat on temperature field in laser cladding process 潛熱對激光涂敷過程中溫度場的影響
Numerical simulation on cladding track , fluid flow field and temperature field in laser cladding process with powder feeding 送粉激光熔覆過程中熔覆軌跡及流場與溫度場的數(shù)值模擬
It is found that the effects of the latent heat are not negligible in the laser cladding process and their errors depend on the temperature range during phase transformations and the size of melted material region 計算結(jié)果表明,在激光涂敷過程的溫度場分析中,潛熱的影響不是總可以忽略的,其誤差取決于材料在物相轉(zhuǎn)變時交界面溫差的?圍及材料熔解體積的大小。
