| 摘 要： | Based on theories of heat transfer,physical metallurgy and hydro-mechanical,in order to analyze the effect of welding parameters on species and distribution of reinforcing phases visually and legibly,finite element software ANSYS was used to simulate transient temperature field for SiC_p/AI in“in-situ”weld-alloying/plasma arc welding.The results show that the calculated results approximately agreed with the experimental measured results.So the model is basically correct and credible.Based on the numerical solutions and experimental results,effect of temperature field in different welding process parameters(welding current,welding velocity)on species and distribution of reinforcing phases is analyzed.The results show that adjusting and optimizing temperature field appropriately is an effective method to obtain welded joint with better microstructure and property.
