Heat and Mass Transfer in Reactive Multilayer Systems (RMS)

M. Rühl[1], G. Dietrich[2], E. Pflug[1], S. Braun[2], A. Leson[2]
[1]TU Dresden, Laser and Surface Technology, Dresden, Germany
[2]IWS Dresden, Fraunhofer Institute for Material and Beam Technology, Dresden, Germany

Established joining techniques like welding, soldering or brazing typically are characterized by a large amount of heat load of the components. Especially in the case of heat sensitive structures like MEMS this often results in stress induced deformation and degradation or even damaging ... Read More

Numerical Analysis of the Flow Structure in the Continuous Casting Two-strand Tundish

M. Warzecha [1], J. Jowsa [1], A. M. Hutny [1], P. Warzecha [1], T. Merder [2]
[1] Czestochowa University of Technology, Czestochowa, Poland
[2] Silesian University of Technology, Katowice, Poland

Calculations were carried out for the water model of the investigated tundish, represented on a scale 1:3. Numerical calculations enable to estimate the fluid flow velocities, pahtlines and other parameters. Calculations were done for two different grids. Based on the results, the flow ... Read More

Time-Dependent Thermal Stress and Distortion Analysis During Additive Layer Manufacturing, by Powder Consolidation by Laser Heating

M.S. Yeoman[1], J. Sidhu[2]
[1]1. Continuum Blue Ltd., Tredomen Innovation & Technology Park, Tredomen, Ystrad Mynach, United Kingdom
[2]BAE Systems, Advanced Technology Centre, Bristol, United Kingdom

A time-dependent COMSOL Multiphysics model of an additive manufacture process, which uses powder consolidation by laser heating was developed, providing a platform to better understanding the manufacture process & provide a tool to reduce resulting distortion & optimization of an ... Read More

Simulation of Laser-Material Interactions for Dynamic Transmission Electron Microscopy Experiments

B.W. Reed[1], T.B. LaGrange[1], G.H. Campbell[1], and N.D. Browning[1,2]
[1]Lawrence Livermore National Laboratory, Livermore, CA, USA
[2]University of California Davis, Davis, CA, USA

The Dynamic Transmission Electron Microscope (DTEM) at Lawrence Livermore National Laboratory is a unique instrument able to capture images of fast-evolving microstructure with exposure times of only 15 ns. This is more than six orders of magnitude faster than conventional in situ ... Read More
