The size of the grains affects the physical properties of the metal, like hardness, toughness, strength, mailability, ductility, plasticity. Heating a metal can change the size of the grains. This ball bearing model demonstrates annealing.Ductility is dependent on how far dislocations are able to travel in the metal which is dictated by grain size.Original ball bearings video here: metal heat treatment videos here: can buy my books here: can support me on Patreon here: like these amazing people:Glenn WatsonJoël van der LooMatthew CockeMark BrouwerDenebImage credits:First microscope grain image (1:11):Tugsataydin microscope grain image (1:19):Edward Pleshakov diagrams (4:14, 4:18):Cdang nerdy maths things:
