The addi-tion of RE refines austenite grains, retards grain growth rate, raises Ac_3 and makes no changeto Ac_1. The incubation periods for proeutectoid ferrite and bainite are reduced, and the timefor complete transformation for pearlite and bainite are prolonged by the addition of RE. Thecomputation result are in comformity with the experimental ones.
