Thermo-mechanical modelling of hot flat-rolling of components with curved profiles
… such as, deformation, flow stress, roll force, temperature, etc., should be used, so that new development in each of these areas can be easily incorporated. A deformation submodel, based on the upper bound theorem, is given for the analysis of three-dimensional deformation of the work piece. A …

Study of the thermal behaviours of intumescent silicate materials
… provided a novel set of protocols to assess the high temperature behaviour of the fire protective silicate materials. In the context of this work, the study discusses the structure-property relationships of the silicates, identifies the degradation stages and elucidates the processes involved …

Crystalline, Amorphous, and Liquid Metal-Organic Frameworks at Non-Ambient Conditions
… of a range of physical variables. Pressure- and temperatureinduced crystalline–amorphous and crystalline–crystalline phase transitions have been investigated using in-situ high-pressure/high-temperature powder X-ray diffraction and Raman spectroscopy. Furthermore, these transitions were also …

Thermal Energy Storage Aggregate using Low-Cost Organic Phase Change Materials
… other hand, the icing of pavements during cold temperatures represents significant pedestrian and vehicle safety concerns. De-icing salts and other routine winter maintenance activities are intended to improve safety but have considerable cost and environmental runoff concerns and cause …

Bestimmung der bruch- und schädigungsmechanischen Eigenschaften keramischer Filterwerkstoffe aus Kleinstproben
… - mit entwickelten Miniaturprüfmethoden bei Prüftemperaturen bis 1500°C untersucht. Mit Hilfe des Ball-On-Three-Balls-Tests (B3B) wurde die biaxiale Festigkeit in Abhängigkeit der Prüftemperatur bestimmt. Für die kohlenstoffgebundenen Proben wurde weiterhin der Einfluss der Verkokungstemperatur …

(Na,K) Aluminosilicate Hollandites: Structures, Crystal Chemistry, and High-pressure Behaviour
… phase relation of the K-Na system at different temperatures and pressures, and to determine the physical-chemical properties and high-pressure behaviour of silicate hollandite-type structures containing K and Na in different concentrations. The (Na,K)AlSi3O8 hollandite solid solution has been …

Contribución al desarrollo y caracterización de fotodetectores avanzados basados en nitruros del grupo III
… The three main lines of research have been: high-temperature behaviour assessment, sensitivity to the polarization of light, and application in photoluminescence measurement systems. A theoretical and experimental study on the behaviour of p-i-n photodetectors at high temperatures has been …
