ACTIVE RESEARCH

Paraequilibrium Carburization of Stainless Steels

Low temperature paraequilibrium carburization is being used to surface harden a variety of stainless steels. Hardened cases, 25-20 µm deep can be generated in industrially relevant times and result in materials with vastly improved wear, fatigue, and corrosion resistance.

Oxidation-induced Stresses in Ni-base Alloys

Oxidation-induced stresses in structural alloys, a long-standing problem, is far from understood. The high brilliance of synchrotron X-rays at the Advanced Photon Laboratory at ANL allows for in situ measurements of the evolution of such intrinsic stresses.

 

 

POTENTIAL IMPACT

The carburization research can be used for a wide variety of stainless steel components, inasmuch as the conformal carburization process is applied to finished components and entails no dimensional change. The oxidation-induced stress will provide the necessary underpinning to develop more oxidation-resistant Ni-base alloys.
