Open AccessUnderstanding the formation of “false friends” (hidden lack of fusion defects) in laser beam welding by means of high-speed synchrotron X-ray imaging
This paper provides a fundamental understanding of “false friend” formation, i.e., hidden defects associated with lack of fusion, using an experimental setup that allowed an insight into the processing zone ba...

Static Nuclear Magnetisation of Aluminium Measured by Its Influence on the Superconducting Critical Field
We have measured the temperature dependence of the superconducting critical field of Al in the temperature range 17μK ≤ T ≤ 600mK. The external magnetic field necessary to suppress superconductivity in Al decrea...

Modelling of dimensional changes during polymer-ceramic conversion for bulk component fabrication
Shrinkage and porosity generation during conversion of polymer-filler systems into ceramic bodies during pyrolysis is examined. In the presence of an inert filler phase such as Si3N4 or SiC powder dispersed in an...

A Novel Route to Aluminum Nitride Ceramics Using a Polyaminoalane Precursor
Metallic Aluminum is dissolved anodically in an electrolyte, containing a primary amine, an aprotic solvent and a tetraalkylammonium salt. Removal of the solvent and subsequent heating lead to a polymer networ...
