  • Strength and plasticity are the key characteristics of structural materials during the elastic deformation of Tungsten nanocrystals.Dislocation plays an important role in regulating the strength and plasticity of materials,In general,the more difficult the dislocation slip,the stronger the material The second phase is often used to hinder the dislocation motion to improve the strength of the material. For exampleCeramic phases can be used to strengthen metals because of the large difference in elastic modulus between the matrix and the second phase and the seve re interface mismatch.Unfortunately,the stiffer second phase generally achieves i ts reinforcement at the expense of ductility.In addition,severe dislocation plugging at the interface can lead to localized stress concentrations that can lead to sudde n material failure during service。In essence,it is imperative that the second phase impedes the movement of the dislocation and is compatible with the plasticity of dislocation slip.Through in-situ mechanical test,it can be more convenient to study the changes of the strain field of the material interface so as to achieve the pur pose of the strength and plasticity of the material.
