增强相呈三维准连续网状分布的TiB晶须增强TC4基(TiBw/TC4)复合材料表现出优异的综合性能(室温与高温的强度与塑性)，并且调控网状结构参数(局部与整体增强相含量、网状尺寸)可以获得不同性能特点(高强度、高塑性、高强韧性、高耐热性)，具有较大的应用潜力。进一步采用高温压缩与超塑性拉伸的方法，研究不同网状结构参数TiBw/TC4复合材料在不同变形方式(压缩与拉伸)及不同变形条件(温度、应变速率、变形量)下的应力-应变行为，建立其高温压缩与高温拉伸本构方程及热加工图，借助其增强相三维网状分布特征，阐明网状结构参数、变形方式、变形条件对TiBw/TC4复合材料组织与性能演变的影响规律，全面揭示其塑性变形机理，并优化其高温压缩与超塑性拉伸最佳变形条件。为不同网状结构参数TiBw/TC4复合材料塑性变形加工与超塑性成形建立理论与实验基础，为其在航空航天上广泛应用提供可靠的理论支撑和技术保障。

TiB whiskers reinforced TC4 matrix (TiBw/TC4) composites with a three-dimensional quasi-continuous network distribution of reinforcement exhibited a superior combination of strength and ductility at room temperature and high temperatures. Moreover, different superior mechanical properties (high strength, high ductility, superior combination of strength and toughness or high temperature durability) can be obtained by controlling different parameters of the network structure, such as local volume fraction, overall volume fraction and network size. These advantages render them extensive application potentials. The hot compressive deformation and superplastic tensile deformation with different conditions (temperature, strain rate and deformation degree) will be performed on TiBw/TC4 composites with different structure parameters in order to investigate behaviors of stress and strain of the composites under different deformation kinds (compression or tension). Different constitutive equations and processing maps for hot compressive deformation and hot tensile deformation will be constructed based on stress and strain values obtained from the stress-strain curves. By means of their three-dimensional network distribution of reinforcement, the effects of deformation kinds, network structure parameters and deformation conditions on the microstructure evolution and mechanical property evolution of TiBw/TC4 composites can be clarified, and then the plastic deformation mechanisms of the composites can be thoroughly revealed. Certainly, the optimal deformation conditions can be drawn by analyzing the testing results. The final aim is to construct theory and experiment foundations of plastic deformation processing and superplastic forming for network structured TiBw/TC4 composites with different parameters, and then provide theory support and technique guarantee for their extensive applications in aerospace industry.
