摘要:
為了探究30CrMnSiNi2A鋼電子束焊接接頭的組織與性能,采用電子束焊接工藝對12 mm厚30CrMnSiNi2A鋼進行了焊接,并對焊態及完全熱處理態的接頭進行了室溫拉伸和沖擊韌性試驗。結果表明:該鋼的電子束焊接工藝性良好;焊態及完全熱處理態的接頭拉伸斷裂均位于母材,經完全熱處理后的接頭強度比焊態接頭強度提高近一倍,略高于同狀態下母材的強度,延伸率及斷面收縮率與母材相當,室溫沖擊韌性略高于母材;焊態焊縫組織主要表現為粗大針狀馬氏體與殘余奧氏體組織,經完全退火處理后焊縫及熱影響區組織主要表現為回火馬氏體組織和殘余奧氏體組織,母材組織為回火馬氏體及少量的殘余奧氏體組織;接頭與母材的沖擊斷裂均表現為韌性斷裂。
Abstract:
In order to explore the microstructure and properties of 30CrMnSiNi2A steel electron beam welded joint,the welding process was used to weld the 12 mm thick 30CrMnSiNi2A Steel,and the tensile and impact toughness tests at room temperature were carried out for the welded and fully heat treated joints. The results show that the electron beam welding technology of the steel works well. The tensile fracture of the welded and fully heat-treated joints is located in the base metal. The strength of the joint after the full heat-treatment is nearly twice as much as that of the welded joint,slightly higher than that of the base metal under the same state. The elongation and the reduction of the section are equivalent to that of the base metal, and the impact toughness at room temperature is slightly higher than that of the base metal. The microstructure of weld seam is mainly the coarse acicular martensite and retained austenite. After full annealing,the microstructure of the weld and heat affected zone is mainly tempered martensite and retained austenite. The microstructure of base metal is tempered martensite and a small amount of retained austenite. The impact fracture of the joint and base metal is ductile fracture.
