摘　　要：以ZL101为基体材料,采用机械搅拌混合盐原位反应法(K_(2)TiF_(6)+KBF_(4))制备原位TiB_(2)增强的ZL101铝基复合材料,研究了TiB_(2)对ZL101的增强效果。对不同质量分数TiB_(2)制备的铝基复合材料进行了XRD物相分析、微观组织及力学性能分析。研究结果表明:所制得的TiB_(2)质量分数为3%的铝基复合材料组织细小,分布均匀,TiB_(2)颗粒尺寸在0.5μm~1μm之间,抗拉强度达到182.58 MPa,屈服强度75.85 MPa,复合材料的力学性能得到大幅提高。In situ TiB_(2)-reinforced ZL101 aluminium matrix composites were prepared by a mechanically stirred mixed salt in situ reaction method(K_(2)TiF_(6)+KBF_(4))using ZL101 as the matrix material.In this paper,the XRD physical phase analysis,microstructure and mechanical properties of the fabricated ZL101 containing different contents of TiB2 were carried out.The results demonstrate that the fabricated 3%TiB_(2)/ZL101 composites exhibit a finely organised and uniformly distributed microstructure,with TiB_(2)particle sizes ranging from 0.5 to 1μm.The tensile strength of these composites reaches 182.58 MPa,while the yield strength is 75.85 MPa,indicating a substantial improvement in the mechanical properties of the composites.
