利用G相制备了两种新型铁素体钢(XD-2Ti和XD-2Nb)。显微组织观察证实，经过短时时效处理后，纳米级G相均匀分布在铁素体基体中。在XD-2Ti和XD-2Nb钢中也观察到了微米级Laves相(Fe2Ti和Fe2Nb)。显微硬度峰值XD-2Ti为495HV，XD-2Nb为368HV，表明G相具有较强的析出强化作用。这些结果从根本上改变了以前接受的关于G期的事实，根据G期被认为是只有在长达数万小时的长期老化后才会发生的恶化阶段。
Two novel ferritic steels (named as XD-2Ti and XD-2Nb) were prepared by the application of G-phase. Microstructure observations confirmed that nanoscale G-phase gets uniformly distributed in the ferritic matrix through the short-time aging process. Micro-sized Laves phases (Fe2Ti and Fe2Nb) were also observed in both XD-2Ti and XD-2Nb steel. The micro-hardness peak value (495 HV for XD-2Ti and 368 HV for XD-2Nb) implies that G-phase has a strong precipitation strengthening effect. These results radically changed previously accepted facts about G-phase, according to which it was regarded as a deteriorated phase that occurs only after long-term aging of up to tens of thousands of hours.
