Influence of Formation and Coarsening of the Laves Phase on the Mechanical Properties of Heat-Resistant Ferritic Steels

Three newly designed heat‐resistant ferritic alloys containing the intermetallic Laves phase were investigated with respect to an annealing dwell time of up to 1440 h at 900°C and were compared with commercially available steels. A detailed characterization of the microstructure evolution in dependence of the annealing dwell time was performed. In order to estimate the influence of Laves phase formation and coarsening on the strength, ductility...
