Minh-quy Le , Young-hun Chae , Seock-sam Kim

材料科学技术（英文）

The sliding wear behaviors of a single layer Al2O3-30 wt pct ZrO2, a double layer Al2O3-30 wt pct ZrO2/Ni-Cr and a single layer Al2O3-13 wt pct TiO2 coating deposited on low carbon steel by plasma spraying were investigated under lubricated conditions with various normal loads. The plastic deformati...

Thermodynamic discussion on Young's equation in wetting

Zeitschrift Fur Metallkunde

Young's equation is discussed on a thermodynamic basis. The result shows that the equation is a thermodynamic equilibrium of the wetting system rather than a force balance. The equilibrium satisfies the general equilibrium condition, that is, Gibbs free energy should b...

Determination of reduced Young's modulus of thin films using indentation test

Wuzhu YAN

金属学报(英文版) doi:10.1016/S1006-7191(08)60125-8

The flat cylindrical indentation tests with different sizes of punch radius were investigated using finite element method (FEM) aimed to reveal the effect of punch size on the indentation behavior of the film/substrate system. Based on the FEM results analysis, two methods was proposed to separate f...

Effect of Zr and Sn on Young's modulus and superelasticity of Ti-Nb-based alloys

Materials Science and Engineering a-Structural Materials Properties Microstructure and Processing

Quaternary Ti-(20-26)Nb-(2-8)Zr-(3.5-11.5)Sn (.wt%) alloys were investigated to evaluate the effects of Zr and Sri on Young's modulus and superelasticity of Ti-Nb-based alloys. X-ray diffraction analysis showed that solution-treated alloys have beta + alpha", beta + om...

Axial Young's modulus prediction of single-walled carbon nanotube arrays with diameters from nanometer to meter scales

Applied Physics Letters

Based on a self-similar array model, we systematically investigated the axial Young's modulus (Y-axis) of single-walled carbon nanotube (SWNT) arrays with diameters from nanometer to meter scales by an analytical approach. The results show that the Y-axis of SWNT array...
