High-energy X-rays give industry affordable way to optimize cast iron

09-Dec-2015

Cast iron can be modified through the manufacturing process to optimize its mechanical and physical properties, such as strength and durability. But the manufacturing process is as much art as science, producing good results yet not capturing cast iron's full potential. Controversy still exists ...
