(J025)Effects of thermomechanical treatment on the microstructure and mechanical properties of harmonic structure designed Ti

摘要

The harmonic structure (HS) designed materials have gained enormous recognition owing to their potentiality in achieving improved mechanical performance [1] 1]. The HS design consists of a specific spatial distribution of coarse grains ( core) surrounded by a ore) network of ultra ultra-fine grains ( Shell). The thermomechanical process (TMP) involving plastic deformation and its annealing is widely used to achieve controlled properties of materials materials. The he TMP of conventional homogeneous structured Ti ha has been studied intensively intensively. However, as such, TMP behavior was as is unknown for the HS designed Ti (HS HS-Ti). In the present study, the effects of TMP treatments on HS HS-Ti are presented and discussed.
