Public Abstract	Researchers at Purdue University have developed a method of cryogenic quenching in the surface treatment of aluminum alloys. This technique uses high cooling rates to allow for a surface hardness similar to that of a T6 temper without the need to heat the workpiece in a high temperature furnace. In addition to heat treatment, this method can also be used to cool the alloy following laser material deposition. This technology represents a step forward for the surface treatment of high hardness aluminum alloys. Advantages: - Similar hardness to a T6 temper - Does not require a high temperature furnace - Can be used for surface buildup via material deposition Applications: - Tempering aluminum alloys - Laser cladding of aluminum alloys Technology Validation: This technology has been validated through laboratory validation.
