Improvement of T8 Steel Solidification Structure by Electropulse Treatment
-
摘要: 對高于熔點、含碳0.8%的T8鋼液使用電脈沖進行處理.將處理過的T8鋼液正常空冷,得到了晶粒明顯細化、枝晶發達程度大大減小的凝固組織.并且發現經過電脈沖處理后的T8鋼的珠光體形態發生了顯著的變化,片層間距縮短.根據實驗結果推導了脈沖電壓和凝固晶粒個數的經驗公式.Abstract: The Grain sizes of solidification structure of T8 liguid steel were reduced significantly after electropulse treat ment. The form of dendrites was disappearing when the electropulse voltage rose. The shape of steel perlites was also changed after electropulse. A empirical equation was obtained between the number of crystals and electropulse voltage.
