摘要
添加氮化钛（TiN）可通过细化晶粒降低激光粉末床熔融法制造的铁铬铝合金的开裂敏感性。然而，添加了 TiN 的 FeCrAl 合金的氧化行为迄今尚未见报道。在本研究中，研究了添加 0.5 至 1.1 w% Ti 的添加剂制造（AM）FeCrAl 合金在 1250 °C 空气中 1000 小时的高温氧化情况。AM 添加 Ti 的 FeCrAl 合金显示出比铸造参考合金更高的氧化率。描述了模型 AM 合金在高温暴露期间的降解动力学，并结合微观结构检查进行了讨论。结果表明，钛的添加会影响剥落动力学。在铁铬铝材料中首次发现了金属/氧化物界面上 TiN 沉淀的形成及其在 1250 °C 暴露期间在氧化铝鳞片内的生长。
Oxidation Behavior of Additively Manufactured Ti-added FeCrAl Alloys
Additions of titanium nitrides (TiN) can reduce cracking sensitivity of FeCrAl alloys manufactured by laser powder bed fusion through grain refinement. However, the oxidation behavior of TiN-added FeCrAl alloys is not reported up to date. In the present work, high-temperature oxidation of additively manufactured (AM) FeCrAl alloys with Ti additions from 0.5 to 1.1 w% has been studied in air at 1250 °C during 1000 h. The AM Ti-added FeCrAl alloys have shown a higher oxidation rate than their cast reference alloy. The degradation kinetics during high-temperature exposure of the model AM alloy are described and discussed with respect to the microstructural examination. The Ti addition is shown to affect the spallation kinetics. The formation of TiN precipitates at the metal/oxide interface and their growth within the alumina scale during the exposure at 1250 °C were revealed for the first time in FeCrAl material.
期刊介绍：
Oxidation of Metals is the premier source for the rapid dissemination of current research on all aspects of the science of gas-solid reactions at temperatures greater than about 400˚C, with primary focus on the high-temperature corrosion of bulk and coated systems. This authoritative bi-monthly publishes original scientific papers on kinetics, mechanisms, studies of scales from structural and morphological viewpoints, transport properties in scales, phase-boundary reactions, and much more. Articles may discuss both theoretical and experimental work related to gas-solid reactions at the surface or near-surface of a material exposed to elevated temperatures, including reactions with oxygen, nitrogen, sulfur, carbon and halogens. In addition, Oxidation of Metals publishes the results of frontier research concerned with deposit-induced attack. Review papers and short technical notes are encouraged.
