The effect of current on resistance spot welding joints on metallurgic and mechanical properties is investigated experimentally using galvanized unequal-thickness DP600 steel sheets. The specimens were chosen to be 1.5 and 1.8 mm thicknesses. The parameters of the welding pro...
In this study the thermal characteristics of Ni/poly-Si contacts subject to an electrical current stressing were investigated. The self-heating induced contact temperature rises were measured for the Ni/poly-Si contacts having different contact resistivity, poly-Si sheet resistance and contact geometry...

Ageing is associated with an attenuated hypertrophic response to resistance training and periods of training interruptions. Hence, elderly would benefit from the ‘muscle memory’ effects of resistance training on muscle strength and mass during detraining and retraining. As the underlying mechanisms are ...
Effects of unilateral strength training and detraining on bone mineral mass and estimated mechanical characteristics of the upper limb bones in young women The aims of this study were to examine the effects of 12 months unilateral high-resistance strength training and 8-month detraining on bone ...
The capacitance–voltage (C–V) and current–voltage (I–V) characteristics of the Ti/p-Si Schottky barrier diodes (SBDs) have been investigated taking into account the effect of the interface states and series resistance of the device. The forward C–V measurements have been carried out in ...
MRA Shawon,F Gulshan,ASW Kurny 摘要: 1.5mm thick sheet metal coupons of austenitic stainless steel and plain low carbon steel were welded by resistance spot welding technique. The effects of welding current in the range 3–9kA on the structure and mechanical properties of welded joint were ...
It is important to perform an optimization of the electrode placement in the design of the physical device as it plays a role in reducing the current crowding.7For example, when the separation between the two electrodes is large, the differences in the resistance of various current conduction pa...
In this paper, resistance spot welding were performed on 1mm-thickness magnesium AZ31B plates. The effect of welding current on the microstructure and tensile shear force was investigated. It was found that the welding current governed the nugget growth, and the nugget could not form if current ...
On the basis of equations developed here, the contribution of the resistance of the oxide film to the potential and current distribution throughout the bed was compared with the macroscopic homogeneous approach. 展开 关键词: atrazine adsorption isotherms electroanalysis pesticide DOI: 10.1023/A:...
