Abstract: Systems and methods for regulating hydrogen concentration in structural materials by electrochemically controlling hydrogen desorption to promote recovery from hydrogen embrittlement are disclosed. Embrittled material can be exposed to an electrolyte and a counter electrode to set up a potential across the material to induce the electrochemical oxidation of atomic hydrogen (H) in the surface of the material. Oxidation reduces hydrogen concentration near the surface, increases hydrogen diffusion toward the surface, and eventually accelerates hydrogen desorption through and out of the material. In some embodiments, a catalyst can be applied to the surface of the material to return the material to its original state before embrittlement.

Abstract: A method to achieve full densification and grain size control for sintering metal materials, wherein raw material powder is deagglomerated to obtain deagglomerated powder with dispersion. The deagglomerated powder is granulated by spray granulation. The granulated particles are processed by high-pressure die pressing and cold isostatic pressing. The powder compact is sintered by two-step pressureless sintering. The first step is to heat up the powder compact to a higher temperature and hold for a short time to obtain 75-85% theoretical density; the second step is to cool down powder compact to a lower temperature and hold for a long time. The two-step sintering can decrease the sintering temperature, so that the powder compact can be densified at a lower temperature. Thus, the obtained refractory metal product is densified, with ultrafine grains, uniform grain size distribution, and outstanding mechanical properties.
