Comparative Experimental Study on Domestic(GH4169)and imported bars(Inconel718)
By comparing and analyzing the chemical composition,metallographic structure,mechanical properties,and other aspects of GH4169 and Inconel718 materials,the advantages,differences,and material characteristics of the two materials had been identified,as well as their applicability.The material performance tests were conducted on three domestic GH4169 materials and imported(Inconel718)materials,confirming that the domestic materials were leading or even better than imported materials in terms of mechanical properties.More important guiding value was provided for the application of aerospace standard GH4169 material.
