Anisotropic Size Effect on the Plastic Deformation Behavior of α-Ti 14th

Anisotropic Size Effect on the Plastic Deformation Behavior ...

14th International Conference on technology of Plasticity, ICTP 2023

作者： Zhang, Haidong Deng, Lei Wang, Xinyun Tang, Xuefeng Jin, Junsong State Key Laboratory of Materials Processing and Die and Mould Technology Huazhong University of Science and Technology Wuhan China

α-Ti sheets are widely used in manufacturing miniaturized components for the outstanding specific strength, corrosion resistance, and formability. However, the size effect brings severe challenges to the deformation and the service of micro parts, and the plastic anisotropy of α-Ti makes the micro-forming process more complicated. Therefore, a series of in-situ experiments and full-field crystal plasticity simulations were carried out to investigate the coupling effect of geometric size and plastic anisotropy of α-Ti. Anisotropic size effect on the plastic deformation was observed, and Diagonal Direction (DD) specimen shows a higher size effect sensitivity than that of RD (rolling direction) and TD (transverse direction) specimens. The flow stress and fracture strain decrease as the geometric size decreases, and the DD specimen shows a higher fracture strain reduction. Evident surface roughing and a higher proportion of hard-oriented grains in DD4 results in stronger intergranular strain heterogeneity, which leads to the formation of through-thickness shear bands as the geometric size decreases. The fracture mechanism in α-Ti transforms from a micro-void coalescence ductile mode to a brittle one as the geometric size decreases. These findings provide a fundamental understanding of the anisotropic size effect on the tensile behavior of α-Ti. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Electronics over flexible substrates offer advantages of flexibility, portability and low cost, and promising applications in the areas of energy, information, defense science and medical service. In recent years, tremendous progress has been witnessed in the development of flexible wearable devices that can be potentially massively deployed. Of particular interest are intelligent wearable devices, such as sensors and storage cells, which can be integrated by flexible magnetoelectronic devices based on magnetic thin films. To examine this further, the magnetic properties of FeNi thin films with different thicknesses grown on flexible graphene substrate are investigated at room temperature. The coercivity increases with increasing thicknesses of FeNi thin film, which can be attributed to the increase of grain size and decrease of surface roughness. Moreover, the thickness modulated magnetic property shows a magnetic anisotropy shift increase with varying thicknesses of FeNi thin film by using measurements based on ferromagnetic resonance, which further enhances the resonance frequency. In addition, the resonance peak is quite stable after bending it for ten cycles. The result is promising for the future design of flexible magnetoelectronic devices.
