摘要：
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: (01 (1) over bar1)(C)(14)//((1) over bar 10)(B2) and [2 (11) over bar0](C14)//[001](B2). The present study indicates that the feasibility that Laves phases can be introduced into metallic materials by deformation processing. (C) 2018 Elsevier B.V. All rights reserved.
