Metal-Hydrogen System Under Extended p, T Conditions

摘要: The preceding chapters have dealt with the properties of hydrogen in metals or metal hydrides under ordinary conditions p, T. In this chapter, we try to extend range our discussion and treat binary M-H systems over entire composition range, including elemental hydrogen, much wider ranges Recent progress high-pressure technology has allowed study very high pressures, consequence making it possible not only dissolve a larger amount but also retain solution at higher temperatures. This opens possibility common end member, being approached on phase diagram via routes Even more can be expected sufficiently pressures: is become metallic form alloys many other elements. Thus, believed that there compelling reason try, time, describe thermodynamical system composition, extended T conditions, even though, by necessity, content will rather preliminary stage.
