10.1 Solidification Times for Various Shapes

 

• First used about 6000 years ago, casting continues to be an important manufacturing process for producing very small, very large, and complex parts.
• The first topic described is solidification of molten metals, including the differences between solidification of pure metals and alloys.
• Fluid flow in casting is then described, with Bernoulli’s and the continuity equations being applied to establish a framework for analyzing molten metal flow into the cavities of a mold.
• The importance of turbulent versus laminar flow is introduced. ...
