Abstract:
The term solidification is commonly used to imply the formation of a crystalline phase from a liquid or melt, although the nutrient phase could also be gaseous. The article s concerned only with the formation of a solid from a melt. Here, the phase transformation is driven by the extraction of heat from the melt and the progress of the transformation is properly separated into two parts i the initial nucleation of crystals, and ii the growth of these initial nuclei by the accretion of atoms from the melt. Much has been written concerning the initial nucleation of crystals and only slight mention of it will be made. The main concern is with the growth of a crystal once it has been formed. Attention has been given to three important aspects of crystal growth from the melt i solute manipulation during crystal growth, ii solid-liquid interface morphologies, and iii defects introduced during crystal growth.
