| 摘 要： | 机械合金化3TUS～2C粉体,会细化晶粒,产生显微应力.在室温下,放置空气中1 d后,即有少量sn晶须出现,长约20um;半年后,会形成大量直径约0.3～1 um,长约100um的细晶须,以及直径约1-3um,长达1.2 mnl的粗晶须.最后,探讨了Sn晶须的形成与自发生长机制.

| Abstract: | Mechanical alloying of 3Ti/Sn/2C powder may refine the grains and produce the micro-strain. A small amounts of Sn whisker with the size of 20 m presented in air at the room temperature. After semi-year, a large amounts of fine Sn whisker with a diameter of 0.3~1 m and a length of 100 m and coarse ones with a diameter of 1~3 m and a length of 1.2 mm were formed. At last, formation and spontaneous growth mechanism of Sn whisker were discussed. |
