摘要
采用累积叠轧焊法制备超细晶硅钢薄板,并对其微观结构、力学性能及断裂方式进行分析。累积叠轧后材料晶粒呈扁平状,抗拉强度显著提高。硅钢断口边缘呈现解理断裂的“河流花样”,心部存在少量的韧窝。
Accumulative Roll-Bonding(ARB) is employed to make ultra-fine grain structures in silicon steel. Microstructure,mechanical properties and fracture surface are examined. The materials processed by ARB have lamellar ultra-fine grains, and the tensile strengths are improved remarkably. Fracture surfaces show predominant cleavage river pattern with a small quantity of dimples in the core.
