- Abstract
The growth of Sn whiskers on Ti2SnC has raised concerns about its stability. It is found that active Sn atoms resulting from the damage of Ti2SnC grains are the culprit of the whisker growth, which is the rationale for the inhibition strategy exploration herein. The inhibition effect on the whisker growth of several metallic phases (Pb, Bi, Al) with different solubility for Sn is evidenced and discussed. Under the same conditions, the Sn whisker growth trends increase from Ti2SnC–Pb, Ti2SnC–Bi and Ti2SnC–Al to Ti2SnC samples, meaning that metallic phases with high solubility for Sn can absorb active Sn atoms to inhibit whisker growth. Therefore, compositing with metallic phases which can accommodate an appreciable concentration of Sn is an effective way to repress Sn whisker growth. The findings confirm the fundamental role of active atoms in whisker growth and provide an effective strategy to overcome the Sn whisker growth problem.
