摘要
非连续增强钛基复合材料(DRTMCs)具有高比强度、低密度、优异的耐蚀性等诸多特性,在航空航天、国防工业、交通运输等领域具有广泛的应用前景.石墨烯具有良好的本征物理和力学性能,是近年来的二维碳纳米"明星"材料,被视为极具潜力的DRTMCs纳米增强体.国内外研究者聚焦DRTMCs设计与制备,突破了低温快速成型和界面改性等关键技术,初步实现了界面精细调控和微观构型,获得石墨烯在钛基体中的本征增强,制备出强塑性匹配较好的DRTMCs.简要综述近些年来石墨烯增强钛基复合材料的设计方法和制备工艺,探讨界面反应、界面结构、微观构型等关键因素对复合材料力学性能和失效机制的影响规律,并提出石墨烯增强钛基复合材料未来的发展方向.
Abstract
Discontinuously reinforced titanium matrix composites(DRTMCs)have many excellent properties such as high specific strength,low density,superior corrosion resistance,which have become ideal candidates for aerospace,defense industry and transportation field and have a wide range of applications.Graphene,as a two-dimensional carbon nano"star"material with excellent intrinsic physical and mechanical properties,has been regarded as a promising nano-reinforcement for DRTMCs in recent years.Recently,domestic and foreign researchers have been focusing on solving the key issue of severe interfacial reaction caused by traditional high-temperature sintering through rapid low-temperature con-solidation as well as powder modification,established a precise interface control method for graphene-reinforced Ti compos-ites,and optimized the configuration to realize the graphene nanoplatelets intrinsic strengthening.The present work sum-marized the fabrication and design method of graphene reinforced titanium matrix composites in recent years,investigating the effects of interface reactions,interface structure and micro-configuration or other key factors on the mechanical proper-ties,failure mechanism,and prospected the development trend of graphene reinforced titanium matrix composites in the further.
