High-temperature annealing effects on molybdenum-silicon contact substrate for vertically structured silicon quantum-dot solar cells
This paper studies the applicability of sputtered Molybdenum (Mo) thin films on silicon wafers (Mo-Si) to act as contact substrates for vertically structured Si quantum-dot (QD) solar cells. The compatibility of Mo-Si contact substrate with Si QD material ...
2019Microstructural evolution and mechanical property development with nickel addition in low-carbon weld butt joints
Roland Logé, Cyril Cayron, Gaojun Mao, Rui Cao
Four metal powder flux-cored wires with added nickel (Ni) were designed to systematically investigate how Ni influences the microstructure and toughness in low-carbon bainitic weld metals (WMs). The microstructure was safely predicted by utilizing reasonab ...
2018On the Prediction of Hot Tearing in Al-to-Steel Welding by Friction Melt Bonding
Aluminum alloy AA6061 was welded to dual-phase steel 980 (DP980) by the friction melt bonding (FMB) process. Hot tears have been suppressed by controlling the thermomechanical cycle. In particular, the welding speed and the thermal conductivity of the back ...
2018Interface microstructure formation of dissimilar Fe/Fe-Mn-C steel RSW joints
An experiment was developed to simulate the interface between liquid high manganese carbon steel and solid ultra-low alloyed steel in a thermal gradient, corresponding to the nugget/sheet interface of resistance spot welds. Despite the large difference in ...
Elsevier Science Sa2018Shear loaded friction-welded crosswise arranged timber boards
Yves Weinand, Till Vallée, Benjamin Hahn
Friction welding of wood is a bonding technology that can be used for joining timber elements, and in which the adhesive is formed from thermally modified cell wall material within the substrate during the welding process. In this paper, this principle is ...
2017Stability of extended beam-to-girder shear tab connections under gravity induced shear force
Extended shear tab connections are widely used to connect beams to the webs of girders. In the full-depth configuration of extended beam-to-girder shear tabs, the shear plate is typically fillet welded to the web, as well as to the top and bottom flanges o ...
Structural Stability Research Council2017Robotic Assistance by Impedance Compensation for Hand Movements While Manual Welding
Aude Billard, Mustafa Suphi Erden
In this paper, we present a robotic assistance scheme which allows for impedance compensation with stiffness, damping, and mass parameters for hand manipulation tasks and we apply it to manual welding. The impedance compensation does not assume a preprogra ...
Institute of Electrical and Electronics Engineers2016New parametric equations to estimate notch stress concentration factors at butt welded joints modeling the weld profile with splines
Anton Schleiss, Pedro Filipe De Almeida Manso, Alexandre Jean Pachoud
For fatigue life estimation as well as for fatigue testing analysis of welded structures by local stresses approaches, the stress concentration factor (SCF) at the weld must be known. Full penetration butt welded joints are extensively used in steel struct ...
Elsevier2016Proposed modeling approach of welding procedures for heavy steel plates
A numerical modeling approach is proposed to assess the effectiveness of automatic submerged arc welding procedures for steel plates with thickness larger than 50 mm. The scope of study includes partial joint penetration butt welds, their numerical analysi ...
Elsevier2016Boosting Water Oxidation Layer-by-Layer
Hubert Girault, Manuel Alejandro Méndez Agudelo, Heron Vrubel, Micheal Diarmaid Scanlon, Véronique Amstutz, Jonnathan Cesar Hidalgo Acosta
Electrocatalysis of water oxidation was achieved using fluorinated tin oxide (FTO) electrodes modified with layer-by-layer deposited films consisting of bilayers of negatively charged citrate-stabilized IrO2 NPs and positively charged poly(diallyldimethyla ...
