【摘要】通过对铸造Fe3Al合金在800～900℃温度范围内的抗氧化性能研究,表明铸造Fe3Al合金在高温氧化过程中表面形成了致密的氧化层,具有优良的抗氧化性能。采用铸造Fe3Al合金制备的几种产品的使用效果良好,说明在一定条件下替代Cr Ni系耐热钢是可行的。更多还原

【Abstract】 By researching the oxidation resistance of Fe₃Al alloy at 800～900 ℃,the experiments demonstrate that the surface of Fe₃Al alloy can form compact oxidation layers during high temperature oxidation, which makes Fe₃Al alloy have choice oxidation resistance. Applied effect of several products which adopt Fe₃Al alloy to produce is excellent.It shows that Fe₃Al alloy is possible to substitute heat resistance steel Cr-Ni in some condition.更多还原
