Abstract
Generally, the formation of Laves phase precipitates is induced by heat treatment, and deformation-induced precipitation of these phases has not been reported so far. In this work, we observed the precipitation of the compression-induced C14 laves phase particles along dislocation walls within B2 TiFe phase in a semi-solid sintered TiFeCo alloy. Interestingly, coherent interfaces were formed between the Laves phase and the TiFe parent phase, and the corresponding orientation relationships: (011¯1)C14//(1¯10)B2 and [21¯1¯0]C14//[001]B2. The present study indicates that the feasibility that Laves phases can be introduced into metallic materials by deformation processing.
