microstructural stability of copper electroplate

microstructural stability of metals used for high quality optics is necessary to maintain the low light scatter properties of the optical surface. room temperature recrystallization of metal causes a roughening of the single-point-diamond-turned (spdt) surfaces and increases the light scatter. differential scanning calorimetry, microstruc..

method for strengthening boron fibers. patent application

commercially available boron filters, produced by the chemical vapor deposition of boron onto tungsten wire substrates, are strengthened by treating them in an oxygen plus inert gas (argon) containing atmosphere for a few minutes at about 880 c. high temperature oxidation increases the residual compression on the tungsten core because the..
