通过冷轧实现双峰晶粒结构对于铝镁合金来说仍然是一个挑战。在目前的工作中,通过新型硬板轧制 (HPR) 路线制造了高抗拉强度 (∼525 MPa) 和延展性 (∼14%) Al-9Mg 合金,单道次厚度减少了 75%。由于镁溶质对动态回复/再结晶的严重阻碍作用,增加溶质镁含量可促进 HPRed Al-Mg 合金中的双峰结构和高位错密度。同时具有高延展性和强度主要是由于双峰晶粒结构和高固溶镁含量带来的强加工硬化能力。
Achieving bimodal grain structure via cold rolling remains a challenge for Al–Mg alloys. In the present work, a high tensile strength (∼525 MPa) and ductile (∼14%) Al–9Mg alloy was fabricated by a novel hard-plate rolling (HPR) route with a single-pass thickness reduction of 75%. Increasing solute Mg content promotes a bimodal structure and a high dislocation density in the HPRed Al–Mg alloys due to the severely retarding effect of Mg solutes on dynamic recovery/recrystallization. The simultaneous high ductility and strength is due mainly to the strong work hardening ability deriving from the bimodal grain structure and the high solute Mg content.
