③The fire-resistant mechanism of FR steels is that most of M-A islands remain stable at 600℃and there is some precipitation of alloying elements, which restrains the great decrease of the strength at elevated temperature to preserve well elevated temperature properties.
③耐火钢的耐火机理主要体现在高温下,M-A岛大部分保持稳定,并伴随有合金元素析出强化,一定程度上限制了高温下耐火钢强度的大幅度下降,从而保持良好的高温性能。
