摘要
主要研究了基体组织对蠕墨铸铁抗热裂性能的影响,为高速列车制动盘的合理选材提供依据。试验结果表明:铁素体基体蠕墨铸铁的耐热疲劳性能优于珠光体基体蠕墨铸铁。
In order to provide basis for reasonable select material for high speed train brake, the influence of matrix on hot fatigue resistant property of cast iron with vermiculate graphite has been studied, resulting in that the hot fatigue resistant property of cast iron with ferrite matrix is better than that of cast iron with pearlite matrix.
