Novel Grain Boundary Allotriomorphic Ferrite/ Granular Bainite Duplex High Strength Reinforced Bar with Large Section 具有仿晶界型铁素体/粒状贝氏体复相组织的大截面钢筋
The presence of grain boundary allotriomorphic ferrite can increase the compatible deformation capability of duplex microstructure, improve the crack initiation energy under impact loading; 适量仿晶界型铁素体的存在增加了复相组织的协调变形能力,提高了裂纹形成功;
Ore structures are brecciated, micro-disseminated, gelatineous, earthy, and the textures are automorphic-hypautomorphic granular, over-growth zoning, allotriomorphic granular, replacement remnant, pseudomorphic and strawberry. 矿石具有角砾状、微细浸染状、胶状、土状等构造及自形-半自形粒状、增生环带、草莓状、他形粒状、交代残余、假象等结构。
However by adding Mo, the formation of polygonal ferrite could be suppressed and thus allotriomorphic ferrite was introduced at quite high temperature. This not only caused dislocation strengthening but also enhanced the effect of precipitation strengthening. Mo的加入抑制了多边形铁素体的生成,可以在较高的温度形成非多边形铁素体,不仅带来位错强化,而且有利于析出强化更大限度的发挥。
