6.5 kV n-Channel 4H-SiC IGBT with Low Switching Loss Achieved by Extremely Thin Drift Layer
See details
(Switzerland: Trans Tech Publications, 2016), 9 page(s)
Thin drift layers were used to realize n-channel 4H-SiC IGBTs with an extremely low switching loss. The thickness of a drift layer was 60 µm, which was designed for a blocking voltage of 6.5 kV. An on-voltage of 5.4 V was obtained at a collector current of 100 A/cm2 and the specific differential on-resistance at...

2D Meso-Scale Finite Element Modeling and Simulation of Polymer-Mineral Composite Material
See details
(Switzerland: Trans Tech Publications, 2016), 9 page(s)
Polymer-mineral composite material is prepared by using modified epoxy resin as binder and mineral particles as aggregates. Its excellent damping characteristic and low thermal expansion make it ideal in manufacturing machine tool beds. However, the properties of this material depend on its formula and structure,...

3D Numerical Model of the Subsoil-Structure Interaction and Comparison of the Results with Experimentally Measured Values
See details
(Switzerland: Trans Tech Publications, 2017), 13 page(s)
The influence of the physically-nonlinear behaviour of the structure and interaction between the upper structure and foundation are the aspects which influence the results of the subsoil-structure interaction analysis. The experimental measurement of stress and strain and monitoring of stress-strain relations by i...

3D Topography Analysis of Ball-End Milled H-13 Die Steel Surfaces Using Wavelet Decomposition Method
See details
(Switzerland: Trans Tech Publications, 2016), 10 page(s)
Optical profiler is employed to measure the surface topography of H-13 die steel machined by ball end cutter. By using 2D discret wavelet decomposition, the topographies of different frequency bands are obtained and the influence of cutter posture on varying frequncy bands topography is studied. The results show t...

Abnormal Grain Growth on the Surface of Cold-Rolled AA1235 Aluminum Plate during the Annealing Process
See details
(Switzerland: Trans Tech Publications, 2017), 12 page(s)
AA1235 aluminum alloys were twin roll cast into a 7.0 mm-thick billet and further rolled into a plate with 70% reduction, followed by annealing at 500 C for 8 h. Abnormal grains were found to be formed on the plate bottom surface. SEM, EBSD, and micro X-ray diffraction were used to analyze the mechanism underlying...

About Formability of Ultra-Fine Grained Metallic Materials
See details
(Switzerland: Trans Tech Publications, 2016), 9 page(s)
Ultra-fine grained (UFG) and nanostructured metallic materials obtained via severe plastic deformation typically show very high mechanical strength but low tensile ductility, which dramatically limits their practical utility. Significant efforts were made to improve uniaxial tensile ductility of ultra-fine grained...
