Effect of the Welding Thermal Cycle on the Microstructure and Mechanical Properties of TiC Cermet HAZ Using the Gleeble Simulator

نویسندگان

چکیده

The effect of heat input on the microstructure and mechanical properties TiC cermet in MIG welding has been comprehensively investigated by Gleeble simulation. microstructure, phase composition shear fracture were examined OM (optical microscopy), SEM (scanning electron microscope), TEM (transmission microscope) XRD (X-ray diffraction) analyses. results show that a significant cermet. With particles austenite bonding remaining same, can effectively improve toughness structural strength from 219.9 HV0.01 to 380.5 469 MPa 684 MPa, respectively, as dislocation density increases while increases. When is 3.4 KJ/cm, reaches peak at with increase input, secondary fragmentation increases, crack propagation leads decrease material strength.
