摘要
-115~-165℃温度下在CH4+C2H4液体中使用的新型铸钢0.1C-20Mn-3.5Ni的金相组织、断口形貌和力学性能的试验结果表明,γ+ε构成的双相组织具有良好的低温力学性能。
The structure, fracture morphology and mechanical property of new 0. 1C-20Mn-3. 5Ni cast steel using in CH4+C2H4 at temperature from - 165℃ to-115℃ have been studied. The results show that with γ+ε dual phase structure this cast steel has excellent impact toughness at cryogenic temperature.
