Grain boundaries and deformation … WebHowever, in metals these properties are often incompatible, due to the dependence of the microscopic mechanisms involved in strengthening and damping. Therefore, it would be of interest to develop new materials that simultaneously exhibit good mechanical properties and high damping [3,5]. This is

What is Strengthening and Hardening Mechanisms of Metals

WebStrengthening with fine particles can produce a planar-to-wavy or wavy-to- planar slip mode transition depending on the nature of the dislocation-particle interactions. Particles which are sheared by dislocations tend to produce slip which is coarse and planar. Particles which are bypassed by dislocations lead to fine wavy slip.
