Grain boundary penetration

WebAug 30, 2024 · An abnormal growth of Cu 3 Sn along the grain boundaries of Cu 6 Sn 5 is discovered. • Such abnormal growth occurs only after the exhaustion of Sn. • Rapid grain boundary penetration causes a faster conversion of Cu 6 Sn 5 into Cu 3 Sn. • A mechanism for this abnormal growth is proposed from the Cu and Sn diffusivities.
