TL;DR: In this paper, a volumetric heat transfer model was proposed to simulate the laser powder bed fusion process in part-scale quickly and reliably, which can simulate the building of multiple tracks and layers in part scale dimensions significantly faster than all the numerical models reported in the literature, and the computed results of fusion zone shapes and sizes and cooling rates were found to be in good agreement with the experimentally reported results in builds of three commonly used alloys.

TL;DR: In this paper, the electrical conductivities of Al[sub 2]O[sub 3]/Al composite synthesized by directed oxidation of an aluminum alloy, and sintered Al [sub 2]-O[ sub 3]-4% MgO are measured.

TL;DR: In this article, the evolution of temperature and velocity fields during laser processing of solar cells to produce an ohmic contact between an aluminum thin film and a silicon wafer was studied using a transient numerical heat transfer and liquid metal flow model.

TL;DR: In this paper, a smart, bi-directional, numerical model has been developed to determine three-dimensional temperature and velocity profiles, weld geometry and the shape of the solidified weld reinforcement surface during gas metal arc (GMA) welding of fillet joints.

TL;DR: In this article, two series of specimens with Hammar and Svensson's Cr- and Ni-equivalents (Creq+Nieq) = 35 and 45 wt% were used to cover a wide range of austenitic grades.
