铁素体双相组织能降低粘附力值。
A dual-phase microstructure containing free ferrite has a lower value of adhesive force.
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。
Experiments show that the dual phase structure suitable to wire drawing consists of fine ferrite islands dispersed in the matrix of lath martensite.
其经预先退火得到全部铁素体组织，然后等温淬火得到铁素体和贝氏体双相组织的基体。
The ferrite is obtained first through annealing, then biphase structure of ferrite and bainite is obtained through isothermal quenching.
