Ein Messsystem zur Bestimmung von Partikeltemperaturen in Druckkohlenstaubflammen
… chamber. Method of measurement is the two colour pyrometrie. Particles heat radiation is collected with a glass fibre and detected in an optical unit. Data are sampled and processed with a PC. An existing pyrometer has been optimised for the application to pulverised coal combustion and a new …

New process approaches to metalorganic vapor phase epitaxy of III-nitrides for high power HEMTs
As a promising candidate for future microwave power devices, GaN-based high-electron mobility transistors (HEMTs) have attracted much research interest. However, group III-nitride growth related issues – predominantly the high defect densities due to lacking lattice matched substrates – limit the …

Thermische Analyse des Zerspanens metallischer Werkstoffe bei hohen Schnittgeschwindigkeiten
The temperatures occuring in a machining operation affect the whole process, since parameters as tool wear, material behaviour and friction are influenced. A turning process with cutting speeds up to 100 m/s is investigated in this work for the workpiece materials AISI 1045 steel, AA 7075 …
