The microstructure evolution of two martensitic alloys was investigated, using X-ray diffraction, electron backscatter diffraction, electron channeling contrast imaging and transmission electron microscopy, after interrupted tempering at 700 °C.

Microstructure evolution during tempering of martensitic Fe–C–Cr alloys at 700 °C

• The evolution of structure, size, number density and volume fraction of Cu precipitates in a stainless steel is characterized.
• The evolution of precipitation is well described by the physically based Langer-Schwartz-Kampmann-Wagner modelling.
• The physically based models show promise for predictive simulations in materials design and optimization.
