The microstructure of creep-tested CM186LC Ni-base single-crystal alloy was studied to assess its suitability for use in the gas turbine environment. Creep tests were conducted at 750 degrees C and at stresses of 560 and 675 MPa up to 11 440 h. The microstructure of fractured and terminated specimens was investigated by light microscopy, scanning electron microscopy and analytical transmission electron microscopy. Microstructural analysis revealed the differences in the microstructure of creep-tested CM186LC depending on the stress applied during creep at 750 degrees C.
研究了经蠕变测试的CM186LC镍基单晶合金的微观结构,以评估其在燃气轮机环境中的适用性。在750摄氏度、560和675兆帕的应力下进行了长达11440小时的蠕变试验。通过光学显微镜、扫描电子显微镜和分析型透射电子显微镜对断裂和终止试验的试样的微观结构进行了研究。微观结构分析揭示了在750摄氏度蠕变过程中,根据所施加应力的不同,经蠕变测试的CM186LC合金微观结构存在差异。
