The effect of phosphorus on mechanical properties and thermal stability of fine-grained GH761 alloy has been investigated.The results show that,when the content of phosphorus is in the range of 0.0007-0.040,there are no significant effects on the tensile properties.Phosphorus strongly affects the st...
