An improved Tensile Deformation model for in-situ dendrite/metallic glass matrix composites
Scientific reports, 2015Co-Authors: X H Sun, J W Qiao, Z M Jiao, Zhihua Wang, H J YangAbstract:With regard to previous Tensile Deformation models simulating the Tensile behavior of in-situ dendrite-reinforced metallic glass matrix composites (MGMCs) [Qiao et al., Acta Mater. 59 (2011) 4126; Sci. Rep. 3 (2013) 2816], some parameters, such as yielding strength of the dendrites and glass matrix, and the strain-hardening exponent of the dendrites, are estimated based on literatures. Here, Ti48Zr18V12Cu5Be17 MGMCs are investigated in order to improve the Tensile Deformation model and reveal the Tensile Deformation mechanisms. The Tensile behavior of dendrites is obtained experimentally combining nano-indentation measurements and finite-element-method analysis for the first time, and those of the glass matrix and composites are obtained by tension. Besides, the Tensile behavior of the MGMCs is divided into four stages: (1) elastic-elastic, (2) elastic-plastic, (3) plastic-plastic (work-hardening), and (4) plastic-plastic (softening). The respective constitutive relationships at different Deformation stages are quantified. The calculated results coincide well with the experimental results. Thus, the improved model can be applied to clarify and predict the Tensile behavior of the MGMCs.

a Tensile Deformation model for in situ dendrite metallic glass matrix composites
Scientific Reports, 2013Co-Authors: J W Qiao, Fuqia Yang, P K Liaw, T Zhang, Simo PaulyAbstract:In-situ dendrite/metallic glass matrix composites (MGMCs) with a composition of Ti46Zr20V12Cu5Be17 exhibit ultimate Tensile strength of 1510 MPa and fracture strain of about 7.6%. A Tensile Deformation model is established, based on the five-stage classification: (1) elastic-elastic, (2) elastic-plastic, (3) plastic-plastic (yield platform), (4) plastic-plastic (work hardening) and (5) plastic-plastic (softening) stages, analogous to the Tensile behavior of common carbon steels. The constitutive relations strongly elucidate the Tensile Deformation mechanism. In parallel, the simulation results by a finite-element method (FEM) are in good agreement with the experimental findings and theoretical calculations. The present study gives a mathematical model to clarify the work-hardening behavior of dendrites and softening of the amorphous matrix. Furthermore, the model can be employed to simulate the Tensile behavior of in-situ dendrite/MGMCs.

Tensile Deformation and phase transformation of furnace-cooled Zn–Al based alloy
Materials Science and Engineering A-structural Materials Properties Microstructure and Processing, 2000Co-Authors: Yimei Zhu, Bun LeeAbstract:Abstract Phase transformation and microstructural changes of the furnace-cooled (FC) eutectoid Zn–Al based alloy were studied during thermal ageing and Tensile Deformation using X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. Two types of decomposition of Zn-rich phases η FC ′ and e were detected in both the aged and the Tensile deformed alloy specimens. Precipitates of α and T′ phases were distinctly observed inside the light contrast η FC ′ and e phases, respectively, using back-scattered electron imaging. Under Tensile Deformation at 150°C, the coarse lamellar structure was deformed into fine particulate structure, whilst the fine lamellar structure remained unchanged. The mechanism of Tensile fracture of the alloy is discussed in relation to the stress-induced phase transformation and microstructural change. An intrinsic co-relationship of phase transformation between the aged and Tensile deformed alloy specimens is also discussed.

Tensile Deformation of artificial muscles: Annealed nylon 6 lines
Polymer, 2019Co-Authors: Yi-wei Huang, Wen-shin Lee, Fuqian Yang, Sanboh LeeAbstract:Abstract In this work, we study the Tensile Deformation of chicken muscle fibers and the temperature dependence of the Tensile Deformation of non-twisted nylon 6 lines and twisted nylon 6 (artificial muscles). Both the non-twisted nylon 6 lines and twisted nylon 6 are annealed at different temperatures of 150, 175, 190 and 200 °C. The chicken muscle fibers under Tensile loading exhibit four Deformation stages with the Tensile load being a linear function of the elongation in each stage. The largest Young's modulus (the slope of the load versus the elongation curve) occurs at stage III. For the Tensile Deformation of the annealed non-twisted nylon 6 lines, the Tensile load is proportional to the elongation. For the Tensile Deformation of the twisted nylon 6 (artificial muscles), there exist three stages with the Tensile loading being a linear function of the elongation in stages I and III. The Young's modulus calculated from the load-elongation curves decreases with the increase of the testing temperature. For the testing conditions used in this work, the Tensile Deformation eventually leads to the fracture of both the chicken muscle fibers and the annealed non-twisted nylon 6 lines. The fracture stress of the annealed non-twisted nylon 6 lines decreases with the increase of the testing temperature.

Effect of surface energy on Tensile Deformation of nanotubes
Journal of Physics D: Applied Physics, 2009Co-Authors: Fuqian YangAbstract:Using the theory of linear elasticity, the effect of surface energy on Tensile Deformation of nanotubes is analysed. A closed-form solution of the stress field in a nanotube is derived. The surface energy creates internal stress in the nanotube and causes an increase in the Tensile stress required to produce the same amount of Tensile strain for a nanotube of the same size without the action of surface energy. The internal stress is a function of the surface energies of inner and outer surfaces and is dependent on the size of the nanotube. The Tensile stress is a linear function of the Tensile strain and is dependent on the size of the nanotube in contrast to direct proportionality between Tensile stress and Tensile strain for the Tensile Deformation of linear elastic materials.
