It was found in this investigation that boron exerted considerable influenceon the nucleation and growth of pearlite. In a hypoeutectoid steel, boron delayedthe starting time of pearlite formation at the maximum pearlite formation temp-erature. Boron did not effect the relation of nucleation rate with time butonly increased the incubation period for pearlite nucleation.

从实验结果证明，硼对珠光体的成核及成长是有影响的；在亚共析钢中硼促使珠光体的开始形成时间推迟，增长了珠光体成核的孕育期，但对成核率与时间的关系，在近于A_1温度(700℃)时，略为加速，而在珠光体转变速度最大的温度(650℃)时却没有影响。
