Deformation of Polycrystals (With Diagram) | Metallurgy
In this article we will discus about:- 1. Introduction to Polycrystal 2. Dislocation Motion in Polycrystals 3. Ductility. Introduction to Polycrystal: The study of the basic mechanisms of the plastic deformations is facilitated by the study of plastic behaviour of single crystals. Most of the engineering materials are, however, polycrystalline, which contain a large number of grains with varying orientations. [...]
