Influence of Ca treatment on particle-microstructure relationship in heat-affected zone of shipbuilding steel with Zr-Ti deoxidation after high-heat-input welding
文献摘要：
The effects of Ca treatment on the particle,microstructure,and toughness of heat-affected zone(HAZ)of shipbuilding steel with Zr-Ti deoxidation after high-heat-input welding were investigated.The simulated welding at a high-heat-input welding of 200 kJ/cm was carried out using Gleeble-3800 welding simulation.Then,particle characteristics were char-acterized using an Aztec-Feature automatic particle analysis system.Additionally,an in-situ observation experiment was performed to study the relationships between particle and microstructure by high-temperature confocal laser scanning microscopy(HT-CLSM).The results indicated that the average HAZ toughness at-40℃was increased from 183 to 290 J by adding 0.0026 wt.％Ca.Meanwhile,the formation of acicular ferrite ratio was increased from 49.34％to 60.28％due to the addition of Ca.The scanning electron microscopy results clearly showed that CaO-Al2O3-TiOx-ZrO2-MnS particles could act as effective nucleation sites for the formation of acicular ferrite,which has been verified by the observation of the particle-microstructure relationship under HT-CLSM.Furthermore,particle characterization results show that the cumulative frequency of particles with the size of 1-3 μm was 33.2％in HAZ of Zr-Ti shipbuilding steel but 66.2％in HAZ of Zr-Ti-Ca shipbuilding steel.
