Numerical Simulation of the laser welding.
Comput. Sci., 2008 The model takes into consideration thermophysical and metallurgical properties of theremelting steel, laser beam parameters and boundary conditions of the process. As a resultof heating the material, in the area of laser beam operation a weld pool is being created,whose shape and size depends on convection caused by the Marangoni force. The directionof

Advanced Science, EarlyView.A thermochemically engineered core–shell Si architecture is developed through the controlled evolution of a SWCNT‐coated Mg2Si precursor. The process simultaneously generates a nanoporous Si shell for strain accommodation and Li+ transport, a chemically anchored SiC interfacial layer for robust mechanical and electrical coupling, and a Mg‐containing Si

Multiscale Simulations in Welds
ACI Avances en Ciencias e Ingenierías, 2012 Welding processes involve complex couplings between fluid dynamics, heat transfer and the metallurgical changes experienced by the base metal. Distortion, residual stresses, grain structure, cooling rates, high temperatures and consequently the reduced strength of a structure in and around a weld joint are produced by the localized thermal cycling ...

Advanced Science, EarlyView.A novel B2‐ordered Ti‐Zr‐V‐Al medium‐entropy intermetallic is developed through controlled metastability engineering, which activates an ordered TRIP effect via a new B2→D019‐α2 transformation with a distinctive {0001}α2//{110}B2, <11‐20>α2//<100>B2 orientation relationship. This alloy achieves an elongation of ∼7%, a strength of ∼1.1 GPa, and superior
