Investigation of Macrosegregation Formation in Aluminium DC Casting for Different Alloy Systems
(Journal article, 2018)Direct chill (DC) casting of aluminum involves alloys employing different solute elements. In this article, a qualitative analysis and comparison of macrosegregation formation is presented for three different alloy systems: ... -
Investigation of metallic bipolar plates for PEM fuel cells
(Master thesis, 2011)High cost and a short lifetime are the two main reasons why the PEM fuel cell is yet to be commercialized. The bipolar plate in a PEM fuel cell is alone responsible for about 45% of the cost and 85% of the total weight of ... -
Investigation of pinholes in Czochralski silicon ingots in relation to structure loss
(Journal article; Peer reviewed, 2019)In the production of monocrystalline silicon by the Czochralski process, structure loss frequently reduces yield and increases production time. Structure loss means the transition from monocrystalline to multicrystalline ... -
Investigation of Routes for Improving the Rate Capability of Electrodes in Li-ion Batteries
(Master thesis, 2014)Lithium-ion battery, first introduced to market in 1991 by Sony, is today one of the most popular battery technologies in the world. The development of Li-ion battery applications from portable electronic devices to electric ... -
Investigation of slag and condensate from the charge top in a FeSi75 furnace
(Chapter, 2023)Metallurgical silicon/ferrosilicon is produced industrially in submerged arc furnaces by carbothermic reduction of quartz. In addition to raw materials, oxide impurities are present in the furnace. Accumulated slag is ... -
Investigation of Sodium Sulfate Additions into Cryolite-Alumina Melts
(Journal article, 2016)In the Hall-Héroult process, sulfur impurities may not only emit harmful gases but also reduce current efficiency. To better understand this process, the behaviour of sulfur compounds in a cryolite-alumina melt at 1253 K ... -
Investigation of Spent Refractory Lining in an Anode Baking Furnace
(Journal article; Peer reviewed, 2017)The refractory lining in anode baking furnaces is exposed to harsh chemical environment and thermal cycling. Spent refractory lining from an anode baking furnace after 4000 days in operation was investigated. Variation in ... -
