摘要
钛基复合材料(TMCs)作为新一代轻质高性能金属结构材料在航空、航天等重大装备领域展现出广阔的应用前景.与传统微米增强TMCs相比,纳米增强TMCs在强塑性协同与热变形能力等方面展现出更为显著的优势,但目前由于纳米增强体分散性和热稳定性等问题,材料的性能潜力尚未充分发挥.如何设计TMCs的复合体系和制备途径引入纳米增强体,并在热加工与热处理过程中保持稳定性,一直是纳米颗粒增强TMCs面临的严峻挑战.本文围绕粉末冶金纳米颗粒增强TMCs工艺特点、制备方法、组织特征与力学性能等方面分析研究现状和进展,指出纳米增强体分散性、热稳定性等制约其发展的基础问题,提出未来研究的发展方向.未来应侧重的研究方向有:(1)碳纳米材料增强TMCs的界面反应控制与热稳定设计;(2)纳米颗粒增强TMCs粉体的批量化低成本制备技术;(3)纳米颗粒增强TMCs专用热变形及热处理工艺研究;(4)纳米颗粒增强TMCs组织构型化设计及强韧化机理研究;(5)纳米颗粒增强TMCs材料其他关键力学性能研究.
Abstract
Titanium matrix composites(TMCs),as a new generation of lightweight and high-performance metals are considered to be one of the most promising structural materials in the fields of aerospace,automotive and other high-tech industries.Compared with conventional micron-reinforced TMCs,nano-reinforced TMCs(NRTMCs)exhibit more significant advantages such as the desirable strength and ductility synergies and thermal deformation capacity.However,the performance potential of NRTMCs has not been sufficiently developed due to the problems of dispersion and thermal stability of the nano-reinforcements.How to introduce nano-reinforcements and maintain their stability during thermal mechanical processing has been a serious challenge for NRTMCs.This paper reviews the research progress of the process features,fabrication methods,microstructure characteristics and mechanical properties,analyses and identifies a series of fundamental issues such as dispersion and heat stability of nano-reinforced material that constrain its development,and proposes the directions for future research.The development directions of future research focus on:(1)interface reaction control and thermal stability design;(2)batch production and low-cost preparation technology;(3)research on special thermal deformation and heat treatment process;(4)tissue configuration design and toughness mechanism and(5)other key mechanical properties research of nano-particulate reinforced TMCs.
