抄録

  The γ→α transformation during continuous cooling was simulated by Monte Carlo method on conditions of ten stages of cooling rate and nine stages of austenite grain sizes. The authors have investigated effects of cooling rate and initial austenite grain size on γ→α transformation and ferrite grain growth. Main results obtained are as follows. The relationship between ferrite grain sizes and cooling rate showed that the ferrite grain sizes hyperbolically decreased against the cooling rate until 500°C/s and then the ferrite grain refinement hardly occurred. The ferrite grain sizes were decreased with an decrease of the initial austenite grain sizes. γ→α transformation rate was increased with the refinement of initial austenite grain. A linear relationship between initial austenite grain sizes and final ferrite grain sizes was obtained by simulation of continuous cooling.<br>
