Grain structure orientational change in Ti6Al4V alloys induced by sea water quenching and novel stress relief annealing process

, 2023
We report on the microstructures and properties of Ti6Al4V alloys, which were achieved upon quenching in sea water medium with potential high cooling rate. The Ti6Al4V alloys were quenched at 1000 and 1100 ◦C, respectively.

The effects of field annealing on the magnetic properties of FeSiB amorphous powder cores

, 2017
The effects of transverse magnetic field annealing on the magnetic properties of Fe78Si9B13 amorphous powder cores were investigated. The cores annealed at 400 degrees C under an external transverse magnetic field of 0.5 T show an enhanced and stable ...

Influence of Solidification Rates and Stress-Relief Annealing on the Mechanical Properties of Cast 6063 Aluminium Alloy

European Journal of Engineering and Technology Research, 2018
This paper reports the influence of solidification rate and stress-relief annealing on the mechanical properties of cast 6063 Aluminium alloy (Al6063). Ingots of Al6063 were melted and then cast using sand and metal moulds. Some of the cast samples were heat treated and then cooled in natural air.

The control of the film stress of Cat-CVD a-Si films and its impact on explosive crystallization induced by flash lamp annealing [PDF]

, 2015
Catalytic chemical vapor deposition (Cat-CVD) can produce amorphous silicon (a-Si) films with low film stress, in general, compared to plasma-enhanced CVD, and is thus suited for the preparation of precursor a-Si films for thick poly-Si films applied for
