High-throughput (A)SAXS investigation of the effect of composition on M23C6 carbide precipitation in stainless steel

Precipitation is a family of phase transformations of major technological importance, notably in the metallurgy of structural alloys. While it is known that nucleus composition and interfacial energy play a critical role in the kinetics of the transformation, their evolution in multi-component systems is still poorly understood. It is proposed here to use a recently developed combinatorial methodology to measure the precipitation kinetics of M23C6 carbides in large ranges of the composition space.
