We compare microstructure formation during laser powder bed fusion (LPBF) of a Ti-22Al-25Nb alloy applying low and high pre-heating build plate temperatures. Fast cooling rates during low-temperature LPBF lead to metastable weakly ordered β phase, i

This work deals with the substantially high-temperature hydrogen sensors required by combustion and processing technologies. It reports the synthesis of undoped and Ni-doped TiO2 (with 0, 0.5, 1 and 2 mol.% of Ni) nanoparticles by a co-precipitation

High-temperature gas sensing requires the increase of sensitivity and reduction of cross-sensitivity. The use of TiO2-Nanotubular layers as gas sensors has shown that the selectivity and sensitivity can be influenced by doping with trivalent elements

Reliable data on self-diffusion of aluminium in α-Al2O3 are scarce and do not yet enable deriving quantitative conclusions about the impact of deliberate aliovalent doping. Therefore, the present study (1280 ≤ T/ °C ≤ 1500, pO2 = 200 mbar) was

The deformation behavior of Ti–6Al–4V processed by laser powder bed fusion (LPBF) is investigated by in situ high-energy synchrotron X-ray diffraction (HEXRD) during uniaxial compression. The initial microstructure of the alloy consists of a fine

Oxygen diffusivity in α-alumina is characterised by a scatter band of about one decade and a half in an Arrhenius diagram. In order to control decisive material parameters the present study is based on high-purity single crystals which were delibera
