| Abstract: | The white-like structure along austenitic grain boundaries in HAZ near weld of 40CrMnSiMoVA steel and its effect on toughness of weld are investigated, in datail, with the welding heat simulation technique, the scanning electron-scope and the electron-probe microanalyzer. The factors effecting white-like structure are found and the precautions reducing and eliminating them are presented. |
