•CrB2 particles have been prepared by in-situ synthesis method.•The morphology of CrB2 particles was changed by the different preparation temperatures.•The morphology evolution and growth mechanism of CrB2 were analyzed.
The morphology evolution of CrB2 in Al–Cr–B alloy has been studied in this work. It is found that the final morphology of CrB2 is inevitably influenced by the preparation temperatures. At different preparation temperatures, the CrB2 crystals display various geometric shapes, such as hexagonal plate and hexagonal prism. The morphology transformation of CrB2 is related with the reaction paths and growth mechanisms. Besides, a growth model is proposed to understand the formation of CrB2.
