英标460级钢筋性能时效的研究

MECHINICAL PROPERTIS OF THE BRITISH STANDARD GRADE 460 DEFORMED BARS AFTER BEING AGED

对采用轧后余热处理工艺生产的英标460级钢筋进行不同时间的自然时效后测定其力学性能。结果表明,自然时效后钢筋的屈服强度有较大幅度下降,抗拉强度有小幅度的上升。

The British Standard grade 460 bars,which when quenched with left heat after rolling,are naturally aged for different times.The result show that the yield strength of the bars drop apparently and the tensile strength rise a little.
