铜包覆石墨烯增强316 L奥氏体不锈钢力学性能研究
Research on mechanical properties of 316 L austenitic stainless steel reinforced with graphene coated by copper
摘要
Abstract
The composite powder of graphene coated by copper and 316 L stainless steel was prepared through a molecular level mixing and ball milling, and then it was sintered by SPS to obtain a 316 L stainless steel matrix material reinforced with graphene coated by copper. Effects of graphene and copper on the density, hardness and tensile property of the sintered samples were investigated, and the fracture surface of the tensile samples was observed. The results showed that the stainless steel powder and the graphene coated by copper are mixed uniformly after the molecular level mixing and the ball milling process. Structure of the graphene is stable during the sintering process. Therefore, the graphene coated by copper can significantly improve the density, hardness, tensile strength and yield strength of the sintered stainless steel by 3. 6%, 17. 4%, 35. 8% and 34. 5% respectively.关键词
