If can not be with V-arrangement into solid solution, can not only increase alloy oozes hydrogen performance, but also can have a strong impact on alloy ooze hydrogen
Energy.Can be to need through repeatedly with V-arrangement into solid solution during one or more mixing in Cr, Fe, Al, Co, Ni, Mo, Pd
The test microstructure to tested alloys is tested and observed and analyzed, while will also carry out to the hydrogen performance of oozing of alloy
Determine and judge, the metal that can serve as adding into the metal of solid solution with V-arrangement empirically can just can not be described.But
Need to summarize based on the result to all hydrogen permeability tests and analyze, and combination is added with and hydrogen performance is oozed beneficial to hydrogen separation alloy
Metal after alloy microstructure result of the test be inferred to can with V-arrangement into solid solution metal just can as solute unit
Element.And, for can with V-arrangement into the metal of solid solution whether can merge interpolation favorable influence is caused to hydrogen separation alloy
And need through test of many times and the microstructure to tested alloys is tested and observed and analyzed；Whole process need through
Test after many times, test number (TN) when mixing in particular for multiple solute elements is more.Although test is can be by having
Limit time is realized, but the workload of test is very big, and the time of consuming is also very long, so in Cr, Fe, Al, Co, Ni, Mo, Pd
Plant or multiple selections is added and can not be estimated by common knowledge.
And the atomic percent of the metal of formation solid solution is also just to can determine that through test of many times for 3.5%-9%
Scope.Through verification experimental verification, once the atomic percent of the solute metal of solid solution is formed more than 9%, can not only increase conjunction
The combination property of gold, but also can have a strong impact on alloy ooze hydrogen performance.And the atomic percent of the metal of formation solid solution is little
It is more or less the same with the hydrogen performance of oozing of the hydrogen separation alloy of V-Cu binary in 3.5%, only forms the atom hundred of the metal of solid solution
When dividing than being 3.5%-9%, ooze hydrogen performance and be greatly improved or lifted.
