Ferrite martensite 肥粒形麻田散体 ; 肥粒铁晶粒度
Mainly its metallographic structure consists of acicular ferrite and martensite.
钢的组织主要由针状铁素体和马氏体两相组成。
Experiments show that the dual phase structure suitable to wire drawing consists of fine ferrite islands dispersed in the matrix of lath martensite.
实验表明，适于拔丝的双相组织是在板条马氏体基体上分布着细小的铁素体岛。
The higher initial strain hardening rate and higher strength of dual phase are attributed to rapid strain hardening in ferrite and the load transfer from the ferrite to martensite.
铁素体迅速应变硬化和铁素体到马氏体的载荷传递使双相钢具有较高的初始应变硬化速率和较高的强度。
