chill casting

The crankshaft in the V12 was switched from a forging to a chill casting.

The resulting casting, called a chilled casting, has the benefits of a hard surface and a somewhat tougher interior.

When cast, chill casting is favoured over sand casting as this gives a finer structure that is more amenable to heat treatment.

Approximately 70 percent of aluminium ingots in the U.S. are cast using the direct chill casting process, which reduces cracking.

As a result of a mishap in his foundry, a broken mould caused molten metal to come into contact with cold metal, making the metal surface extremely hard - chilled casting - which he advertised as 'self sharpening' ploughs, and received patents for his discovery.
