摘要

将 IN 713 C 合金制成的拉伸试样在 850 oC 的空气中循环氧化 500 小时，然后在 650 和 750 °C 下评估其拉伸性能。循环氧化暴露已被证实会导致合金拉伸性能退化，从而降低强度和延展性。合金拉伸性能的退化与循环氧化造成的表面损伤和微结构退化有关。此外，拉伸测试过程中 γ′-沉淀物的粗化也是造成观察到的影响的原因之一。

Role of Prior Cyclic Oxidation on Tensile Deformation Behaviour of IN 713 C Alloy

Tensile test specimens fabricated out of IN 713 C alloy were subjected to cyclic oxidation at 850 ^oC in the air for 500 h, and their tensile properties were evaluated at 650 and 750 °C. Cyclic oxidation exposure has been noted to induce degradation in the alloy’s tensile properties, resulting in decreased strength and ductility. The deterioration in the alloy’s tensile behavior is linked to both surface damage and microstructural degradation caused by cyclic oxidation. Additionally, coarsening of γ′-precipitates during tensile testing contributes to the observed effects.

期刊介绍： Metals and Materials International publishes original papers and occasional critical reviews on all aspects of research and technology in materials engineering: physical metallurgy, materials science, and processing of metals and other materials. Emphasis is placed on those aspects of the science of materials that are concerned with the relationships among the processing, structure and properties (mechanical, chemical, electrical, electrochemical, magnetic and optical) of materials. Aspects of processing include the melting, casting, and fabrication with the thermodynamics, kinetics and modeling.
