...Jasper Lienhard; David Veysset; Keith A. Nelson; Christopher A. Schuh At sufficiently high velocities, a microparticle impacting a metal substrate can cause ejection of material from the substrate and impact-induced melting, both of which can result in erosion. Here, we directly image the impact...

... and melting of the metals in the boundary layer to the development of the instabilities is discussed. A microscopic study of the edge of the penetration channel has been made, which shows that the materials have been melted during the interaction between the plate and the jet. 12 08 2009 25 11 2009...

...X. Richard Zhang; Xianfan Xu This work developes a finite element model to compute thermal and thermomechanical phenomena during pulsed laser induced melting and solidification. The essential elements of the model are handling of stress and strain release during melting and their retrieval during...

... aluminum and iron shells on a rigid, perfectly conducting mold. It is assumed that the mold surface has a sinusoidal corrugation with a small aspect ratio, and the surface is perfectly wet by the molten metal which is initially at its melting temperature. The undulatory geometry of the mold surface lead...

... of a finite medium was analyzed using a semi analytical approach. The results showed that if the initial temperature of the medium is different than melting, a possibility of a reversal of the interface motion exists. With increasingly large differences between the initial medium temperature and the phase...
