During the high-temperature forming process of titanium alloy products,the surface will adsorb oxygen,nitrogen,and hydrogen from the atmosphere,forming rich oxygen α contamination layers including layers,oxide layers,and protective coatings.The pollution layer will reduce the tensile strength,elongation after fracture,and other mechanical properties of the material,shortening the service life of the product.This article utilizes Fick's second law to investigate the oxygen rich α layer of TA15 titanium alloy at 860～950℃.By solving at constant temperature,the activation energy of oxygen diffusion was determined to be 211897.4J/mol,and the diffusion curve was obtained.Finally,this article proposes to use area to solve the oxygen enrichment problem of TA1 5 titanium alloy in the process state.This method was suposed to provide ideas for subsequent research.
