研究了含碳的气氛对Fe-3.2Mn-9.4Al-1C-1.27Si合金显微组织和机械性能的影响。当该合金在含碳的大气中,1050℃1小时退火时,发现表面氧化瘤状物和晶界
The effect of carbon-containing atmosphere on the microstructure and mechanical properties of Fe-3.2Mn-9.4Al-1C-1.27Si alloy was investigated. When the alloy was annealed at 1050 ° C for 1 hour in a carbonaceous atmosphere, surface-oxidized nodules and grain boundaries were found
