چکیده

This study conducted a basic investigation to improve the solidification cracking susceptibility of carbon steel. BTR is one susceptibilities cracking, and it said that reduced when smaller. three commercial filler metals was evaluated by using Trans-Varestraint test. EPMA EDS analysis weld metal microstructure revealed two compounds. The white structure composed silicon, manganese, sulfur, black Ti-based compound. Theoretical applying two-phase peritectic model in FA mode considering MnS crystallization during segregation. results indicated steel attributed difference completion temperatures, most deleterious element. Also, MX compound (Ti, C, N) crystallized addition at end solidification. for Ti virtual materials because may lead reduction trapping C liquid phase. showed BTR. amount residual phase an increase due addition. Based on theoretical considerations, can be concluded effective reducing
