It has been found that interphase precipitation, fibrous precipitation, precipitation on dislocation, precipitation from supersaturated ferrite at lower isothermal transformed temperature.
However, the precipitation temperature of all phases can determine by isothermal quenching method.
等温淬火法可以确定所有相的析出温度。

During isothermal holding at low temperature, the nonequilibrium segregation promotes precipitation of boron constituent and establishment of equilibrium segregation at grain boundaries.
