Re: [MW:17510] Effect of grain growth in toughness and Softness of a metal

grain size is directly related to the toughness of the material.larger the grain size,more is the toughness of materials. Grain size and hardness are inversely related,i.e smaller the grain size, more is the hardness. Ductility is directly related to the grain size. Grain growth is increase in the grain size..so if the grain size increases,ductility and toughness increase and hardness decreases. And as far as heat treatment is concerned, plz specify what exactly you want to know

Dear experts,

 

Kindly explain the relation between grain growth, toughness, hardness & ductility. If anybody have some texts which explains the basic changes that happens during heat treatment, please share.
