Material Strengthening Mechanisms is the mechanism that allows for a change in microstructure and mechanical properties due to annealing and recrystallization Mechanisms of Strengthening in Metals General principles Ability to deform plastically depends on ability of dislocations to move Strengthening consists in hindering dislocation motion We discuss the methods of grainsize reduction solidsolution alloying and strain hardening These are for singlephase metals We discuss others when treating alloys Ordinarily strengthening reduces ductility This is based on the fact that it is difficult for a dislocation to pass into another grain especially if it is very misaligned Atomic disorder at the boundary causes discontinuity in slip planes For highangle grain boundaries stress at end of slip plane may See Answer
