摘要
研究了焊条药皮中添加稀土氧化物对熔敷金属热塑性的影响。结果表明,稀土氧化物能提高熔敷金属的伸长率和断面收缩率;并细化了一次结晶组织,使一次结晶组织的方向性明显减弱,促进等轴晶的发展。
The effect of rare earth (RE) oxide addition to electrode coating material on thermal plasticity of weld was investigated. The experimental results show that the elongation and area reduction of weld can improved by adding RE oxide in electrode coating material. Comparing with the weld prepared with RE oxide free electrode the primary crystall are refined and formation of equiaxed crystals is promoted in the weld containing RE oxide.
