Abstract
En 中文
• Quasi-in-situ study reveals coupled effects of Zn & Sn orientation on TM behavior. • β-Sn grain orientation significantly governs thermomigration in low-Zn joints. • Zn addition markedly suppresses Cu diffusion and asymmetric IMC growth under TG. • High Zn content (≥3 wt%) weakens the dependence of TM on β-Sn grain orientation. • Zn alloying and large θ angle enhance shear strength via reinforcing bulk IMCs.
