TL;DR: High accuracy measurements of thermophysical properties for the National Institute of Standards and Technology standard reference material for 316L stainless steel are performed, particularly useful for the validation of multiphysics models of industrial metal processes.
Abstract: In this work, we perform high accuracy measurements of thermophysical properties for the National Institute of Standards and Technology standard reference material for 316L stainless steel. As these properties can be sensitive to small changes in elemental composition even within the allowed tolerances for an alloy class, by selecting a publicly available standard reference material for study our results are particularly useful for the validation of multiphysics models of industrial metal processes. An ohmic pulse-heating system was used to directly measure the electrical resistivity, enthalpy, density, and thermal expansion as functions of temperature. This apparatus applies high current pulses to heat wire-shaped samples from room temperature to metal vaporization. The great advantage of this particular pulse-heating apparatus is the very short experimental duration of 50 $$\upmu {{\hbox {s}}}$$, which is faster than the collapse of the liquid wire due to gravitational forces, as well as that it prevents any chemical reactions of the hot liquid metal with its surroundings. Additionally, a differential scanning calorimeter was used to measure specific heat capacity from room temperature to around 1400 K. All data are accompanied by uncertainties according to the guide to the expression of uncertainty in measurement.

13 Mar 1995TL;DR: In this paper, an improved spray forming atomization ring converter adapted for spray forming of a refined molten metal from a molten metal refining or melting chamber wherein the molten metal is atomized into tiny molten droplets by gas impingement in a stream of molten metal and preferentially directed to and deposited on a target surface.
Abstract: An improved molten metal spray forming atomization ring converter adapted for the spray forming of a refined molten metal from a molten metal refining or melting chamber wherein the molten metal is atomized into tiny molten droplets by gas impingement in a stream of molten metal and to the structure by which the molten metal droplets are preferentially directed to and deposited on a target surface The molten metal spray forming atomization ring converter is adapted to control the flow of liquid metal droplets and to avoid a backflow of such droplets during the gas atomization by providing structure, such as small apertures to the inner diameter of the ring, by providing large holes through the inner diameter and adding a porous metal filter to cover the large holes or by providing a gas supply system independent from the atomization system gas supply, such that a pressure or diffused source of gas is provided at the inner bore These modifications produce a relatively small mass flow of gas sufficient to feed the entrainment requirement of the high speed jets, but sufficiently low enough to avoid preatomization of the liquid metal wherein backsplash of the metal is reduced and/or prevented
