Regarding annealing, choose the right answer (One or more): The actual annealing time must be long enough to allow for any necessary transformation reactions that may occur Annealing can be performed to release internal stresses of the material The main purpose of annealing is to decrease or restore material's ductility Time isn't a significant parameter in annealing process If the rate of temperature change is too great, temperature gradients and internal stresses may be induced that may lead to warping or even cracking

Solidification of metals

The term solidification indicates the conversion of material from the state of liquid to the state of solid. The solid-state is more compact and rigid than liquid, and the solidification indicates the transformation of material from a random state to a more compact and crystalline form. The point at which dendrite formation in liquid starts taking place is referred to as the solidification point.
