TL;DR: In this article, a two-dimensional axisymmetric model for materials removal during laser irradiation is presented by taking into account the reflections of the laser beam at the wall of a laser-induced cavity.
Abstract: A two‐dimensional axisymmetric model for materials removal during laser irradiation is presented by taking into account the reflections of the laser beam at the wall of the laser‐induced cavity. Also, the liquid metal flow due to the shear stress at the interface of the assist gas and the liquid metal is studied in this paper. The vaporization of the liquid metal and the melting of the solid substrate at the liquid‐vapor and the solid‐liquid interfaces, respectively, are modeled by applying the Stefan condition at various points on the interfaces. Maximum drilling rate is determined by considering that the laser energy is used only to melt and vaporize the material. The effects of various process parameters such as the laser power, laser beam radius, and the laser pulse‐on time on the cavity depth, the recast layer thickness, and the cavity tapering are examined in this study. It is found that the laser‐induced materials removal process can be described in terms of a single parameter called the ‘‘gross’’ ...

03 Mar 1975TL;DR: In this paper, a solid state bonding process of malleable metals employing the isothermal solidification of a liquid interface to overcome bonding problems inherent in certain material combinations especially when subjected to high annealing temperatures.
Abstract: A solid state bonding process of malleable metals employing the isothermal solidification of a liquid interface to overcome bonding problems inherent in certain material combinations especially when subjected to high annealing temperatures. The technique employs the use of a solid metal interliner clad between the two components to be bonded which has a lower melting point than the adjacent components, is diffusible into either one or both of the adjacent components and maintains ductility after alloying with the adjacent components. The composite material is then heat treated above the melting point of the interliner causing momentary liquifying of the interliner, diffusing the liquid metal into either one or both of the adjacent components thereby forming a progressively higher melting point alloy and subsequent isothermal solidification of the high melting alloy to securely bond the two components together.

TL;DR: In this paper, a linear relation between the cosine of the contact angle and the temperature of a liquid metal sessile drop resting on a ceramic substrate is established, and the work of adhesion and the effects of surface roughness, porosity, chemical reactions, and structural transformations in the substrate surface are also discussed.
Abstract: A linear relation is established between the cosine of the contact angle and the temperature of a liquid metal sessile drop resting on a ceramic substrate. This relation is demonstrated for many liquid metal/ceramic systems. The work of adhesion and the effects of surface roughness, porosity, chemical reactions, and structural transformations in the substrate surface are also discussed.
