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.

研究了重复会聚拉丝过程中TiB_2颗粒的形态变化及其对杨氏S模数和塑性的影响。主要结果如下：[1]杨氏S模数随TiB_2颗粒数量的增加而线性增加。[2]增加拉丝次数对改善塑性是有效的。[3)通过重复收敛拉丝过程，加入的TiB_2颗粒被溶解并在母线中重新析出。
