The morphology change of TiB2 particles by using repeat converging wire drawing process and its effects on Young' s modulus and ductility were studied. The main results are as follows:[1] The Young' s modulus linearly increases with the amount of TiB2 particles.[2] The increase in the number of wire drawing is effective for the improvement of ductility.[3] The added TiB2 particles are solved and re-precipitate in matrix wire by repeat converging wire drawing process.

研究了重复汇聚拉丝工艺制备的TiB2颗粒的形貌变化及其对杨氏模量和延展性的影响。主要结果如下：[1]杨氏模量随着TiB2颗粒的添加量线性增加。[2]拉丝次数的增加对于延展性的提高是有效的。[3]通过重复汇聚拉丝过程，添加的 TiB2 颗粒溶解并重新沉淀在基体丝中。
