Application of JMatPro Software in Properties Study of Flux Cored Welding Wire W110
By means of JMatPro software,the physical and mechanical properties,phase map and CCT curves of deposited metal of W110 wire for submerged welding were studied.The determinate values of heat physical properties and partial mechanical properties of the deposit metal of W110 wire from room temperature to melting temperature were obtained by calculation.The results indicate that the austenitic transformation temperature of the deposited metal of W110 wire is 692～779 ℃,δ-ferrite exists in 1330～1468 ℃,the solid and liquid phase lines is 1371～1468 ℃.During continue cooling,if cooling speed is higher than 100 ℃/s,there is not carbide in structure;when cooling speed is between 100 ℃/s and 10 ℃/s,two kinds of carbides separate out;if cooling speed is between 10 ℃/s and 1 ℃/s,three kinds of carbides exist;when cooling speed is between 1 ℃/s and 0.1 ℃/s,four kinds of carbides precipitate.
