Model reduction method for the simulation of the selective laser melting process

open access: closedAIP Conference Proceedings, 2019
Selective Laser Melting offers new perspectives in terms of part design and simplification of complex assemblies. However, because such a process is based on the fusion of the material, severe thermo-mechanical conditions arise and are responsible for local plastic deformation, residual stresses and distortion of the manufactured component.

Non-isothermal reduction as a method of determining the softening - melting temperature of iron-ore pellets and sinters

open access: closedSteel Research, 1998
An attempt was made to develop a simplified procedure of determining the softening-melting temperature ranges for iron-ore pellets and sinters. For this purpose, the non-isothermal reduction of a sinter (pellet) sample in a graphite crucible was used in the temperature range of 1000-1550°C, where the sample was heated at a rate of 5K/min.

Direct production of the Nb-10%W-l%Zr-0.1%C alloys from the constituent metal oxides by the combined carbothermal reduction-electron beam melting method

open access: closedJournal of the Less Common Metals, 1983
An investigation of the combined carbothermal reduction-electron beam melting method of preparing NbWZr alloys, which are strong candidates for use as engineering materials in heat engines, is reported. In this process alloying proceeds during the simultaneous reduction of mixtures of oxides of the constituent metals.

A Geometry Method for Calculating the Fiber Diameter Reduction in Melt Blowing

Advanced Materials Research, 2014
Melt blowing is one of the important methods for producing ultrafine fibers. The production of melt blowing is the nonwoven. Fiber diameter has crucial effect on the property of the nonwovens. In the melt-blowing process, many achievements have been published on the fiber diameter distribution along the spinning line.

Single crystal Tl0.3MoO3 growth by electrolytic reduction method of a Tl2CO3–MoO3 melts

Journal of Crystal Growth, 2005
Single crystals of quasi-one-dimensional charge-density-wave conductor blue bronze Tl(0.3)MoO(3) have been grown by electrolytic reduction method using the raw materials Tl(2)CO(3)-MoO(3) with composition around 1:4.3 mol ration. The electrolytic temperature was about 570 degrees C, and electrolytic current was 25 mA during the electrolytic process. By
