Written by leading experts in their respective fields, Solidification and Casting provides a comprehensive review of topics fundamental to metallurgy and materials science as well as indicates recent an industrial perspective, the book begins with chapters on the casting techniques most commonly used in industry today.

AbstractThe surface quality of slabs is closely related with the initial solidification at very first seconds of molten steel near meniscus in mold during continuous casting. The solidification, structure, and free deformation for given steels have been investigated in droplet experiments by aid of Laser Scanning Confocal Microscope.

It is observed that the Cited by: 1. The typical models are applied for the numerical simulation of heat and mass transfer with phase change for the new inverse casting technology and the traditional CSP technology. The results show that the effect of micro mass transfer models on the perfection of continuous solidification processes for Fe - C alloy cannot be omitted for coupled Author: Yanhui Feng, Xinxin Zhang, Wenfei Wu.

Solidification of molten metals during various casting methods poses many practical problems associated with phase transformation and heat transfer processes. Evaluation of solidification time is one of the very important parameters used for assessing the properties of the material.
