Splat quenching

Splat quenching is a metallurgical, metal morphing, technique used for forming metals with a particular crystal structure by means of extremely rapid quenching, or cooling.

A typical technique for splat quenching involves casting molten metal by pouring it between two massive, cooled copper rollers that are constantly chilled by the circulation of water. These provide a near-instant quench because of the large surface area in close contact with the melt. The thin sheet formed has a low ratio of volume relative to the area used for cooling.
