Abstract

The phase composition and microstructure of sintered powder materials based on multicomponent mixtures of Ti + Al + (Fe + Fe₂O₃), where one of the components is an oxidized steel swarf powder, has been studied. Two variants of the ratio of titanium and aluminum with the same volume content of swarf powder are considered. It was found that the presence of iron oxide in the initial swarf powder does not guarantee the formation of separate aluminum oxide phases. During vacuum sintering, both in the first version of the composition and in the second one, iron aluminides are mainly formed. The formation of ternary intermetallides TiFe₂Al and complex oxides FeTiO₃ was also observed.

Ti-Al-(Fe-Fe2O3)粉末混合物烧结过程中组分的相互作用特征

研究了Ti + Al + (Fe + Fe2O3)多组分混合烧结粉末材料的相组成和显微组织，其中一种组分为氧化钢屑粉。考虑了相同体积含量的钛铝比的两种变化。研究发现，初始屑粉中氧化铁的存在并不能保证形成单独的氧化铝相。在真空烧结过程中，无论是第一版组合物还是第一版组合物，都主要形成铁铝化物。还观察到三元金属间化合物TiFe2Al和络合氧化物FeTiO3的形成。
