Description
得られたワイヤに焼入れ焼戻しを施した。焼入れは、表3に示す条件にて行い、焼戻しは、いずれの試料においても450〜530℃で行った。焼入れ焼戻し後に絞り(RA)、オーステナイト結晶粒(旧オーステナイト結晶粒)の平均結晶粒径(平均γ粒径)を測定した。その結果を表3に示す。なお、焼入れ温度を変化させることで平均結晶粒径を変化させた。オーステナイト結晶粒の平均結晶粒径は、JIS G 0552に定められている切断法により算出した。 The obtained wire was quenched and tempered. Quenching was performed under the conditions shown in Table 3, and tempering was performed at 450 to 530 ° C. for all samples. After quenching and tempering, the average crystal grain size (average γ grain size) of the drawn (RA) and austenite crystal grains (old austenite crystal grains) was measured. The results are shown in Table 3. In addition, the average crystal grain size was changed by changing the quenching temperature. The average crystal grain size of the austenite crystal grains was calculated by a cutting method defined in JIS G 0552 .
