【摘要】 借助能谱的成分分析，用透射电镜选区电子衍射（SAED）技术，确定了堆焊金属的组织结构，并对堆焊金属、2.25Cr－1Mo钢母材及304不锈钢的高温（900℃）抗氧化性能进行试验比较．研究结果表明，用Fe-Al则合金条（ω（Al）＝16％）堆焊2．25Cr－1Mo钢，其堆焊层组织为α－Fe（Al）堆焊层金属的高温抗氧化性能优于304不锈钢．更多还原

【Abstract】 The microstructure of Fe-Al alloy clad metal was studied by means of EDS and SAEDtechnology. High-temperature oxidation-resistance property was compared among Fe-Al alloy cladmetal, 2.25Cr- 1Mo steel and 304 stainless steel. The results show that the microstructureof clad metal is α-Fe(Al). High temperature oxidation-resistance property of clad metal is superior to304 stainless steel.更多还原
