electrodeposited Ag-Bi layer,Strengthening mechanisms,TEM,Twin,Stacking faults

This study elucidates strengthening mechanisms in electrodeposited Ag-Bi layers using TEM. Hardness increased at both low and high Bi levels. High Bi samples showed grain boundary Bi segregation, while low Bi samples exhibited twins and stacking faults, enhancing hardness.
