In this section we have gathered some relevant academic research and magazine articles which explains the science behind Deep Cryogenic Treatment (DCT) and the affects it has on various materials.

To summarise, deep sub-zero temperatures physically changes the treated material leaving it stronger, tougher and harder.  The applications are almost limitless from gear sets to brake discs to fish hooks to alloy wheels.

All will be stronger and longer lasting and able to withstand increased stress over an untreated part.

The technology to liquify gas is relatively new and it is still very uncommon in it's use, so unlike testing materials with high temperatures (e.g. quenching steel), testing the effects of deep sub-zero temperatures is still in it's infancy.  In an effort to broaden the understanding of this technology we have been sponsoring cryogenic studies at the University of Leicester for many years helping to further scientific knowledge in this fascinating field.

Below are a few articles and research papers from a variety of sources which will get you started.  A quick google search will show many more academic studies however a lot of empirical testing remains confidential as enterprises (from military to mining to F1) see these performance and cost gains as a competitive edge and are naturally reluctant to share their findings.
