Nickel powder precipitation by high-pressure hydrogen reduction
The effect of impurities on the precipitation behaviour of nickel powder produced by high-pressure hydrogen reduction was investigated in order to determine the factors responsible for the formation of powder with undesirable morphology. In nickel precipitation by hydrogen reduction, two product …

Honeycomb structured porous films from different polymer architectures - preparation, mechanism, analysis and post-treatment
… solutions were examined. Furthermore, the precipitation behaviour of various polymer architectures was inspected. Only the polymer architectures showing a lower viscosity and late precipitation deemed highly regular films. Finally, the modification of highly regular films from a comb …

Investigation of ThO2 as a structural analogue for spent nuclear fuel dissolution under repository conditions
… to gain additional data on the dissolution and precipitation by following the change in isotopic ratio 229Th/232Th. Furthermore, the pellets from these experiments were measured with direct alpha spectrometry to estimate the contents and thickness of the 229Th-rich layer formed on the pellet …

Stability of nickel-base superalloys for turbine disc applications
… stability. An unexpected transition in $\sigma$ precipitation behaviour after 500 hours at 800°C was observed between 12 and 16 at.\% Co. It is proposed that this behaviour may be due to the effect of Co on the $\gamma$/$\gamma^\prime$ partitioning behaviour of other elements. Preliminary …
