摘要：
The effect of the tungsten addition on the mechanical properties of high-purity 60 mass%Cr-Fe alloy was investigated. High-purity 60 mass%Cr-Fe-4 mass%W alloy ingots were prepared by melting in a newly designed high-frequency induction furnace equipped with a cold copper crucible. The purity of the ingots were higher than 99.98 mass% after the analysis of 2 1 elements. The deformability at temperatures of 1273 to 1573 K and the tensile properties between 293 K and 1073 K were measured by Gleeble test and tensile test. It was found that the tensile strength of 60 mass%Cr-Fe-4 mass%W alloy is higher than that of 60 mass%Cr-Fe alloy, and the addition of tungsten is effective in improving tensile properties of a 60 mass'7cCr-Fe alloy.
