What is a solid solution? In general, what is its implication on the mechanical behavior of metals (i.e., increase or decrease in strength)?
In deformation of metals, the slip and atomic dislocation mechanism is so significant because Dislocation motion hardens materials, while ductility reduces. The force required for slip is much less than the force required breaking the metallic bonds. Dislocation motion eases up the materials deformation. Open original
