Most of LCF cracks appear in the late half lifetime and mainly distribute at the columnar grain boundaries,interdendrites,interfaces of slipping bands and MC carbide.
结果表明:加Hf显著提高了合金的LCF寿命,缓冷凝固则严重损害合金的LCF性能;LCF裂纹大多产生于疲劳寿命的后半期,主要出现在柱晶界、枝晶间、滑移带界面以及MC碳化物处;滑移带的出现是LCF损伤的先兆,在滑移作用下MC碳化物群体开裂并向周围扩展留下疲劳条痕,是这类合金中温LCF断裂的重要特征。
