Abstract Liquid metal embrittlement cracks are generated in steel when the steel is in contact with liquid tin bronze. The elimination of liquid metal embrittlement cracks during the arc cladding of tin bronze on steel sheet was investigated. The result showed that liquid metal embrittlement cracks were generated in the bare steel sheet while no liquid metal embrittlement crack was generated in the nickel-plated steel sheet. An iron-based transition zone containing nickel was generated between steel sheet and cladding layer, and nickel had inhibitory effect on the formation of liquid metal embrittlement cracks. Strength and toughness of the steel sheet were improved with the disappearance of liquid metal embrittlement cracks.

钢板锡青铜电弧熔覆过程中液态金属脆化裂纹的消除

摘要 钢与液态锡青铜接触会产生液态金属脆性裂纹。研究了锡青铜在钢板上电弧熔覆过程中液态金属脆性裂纹的消除。结果表明，裸钢板产生液态金属脆性裂纹，镀镍钢板未产生液态金属脆性裂纹。钢板与熔覆层之间产生含镍的铁基过渡带，镍对液态金属脆性裂纹的形成有抑制作用。随着液态金属脆性裂纹的消失，钢板的强度和韧性得到提高。
