Future materials for machine construction must be more advanced and new functional, and easier to recycle at the same time. This paper describes the potential of use of hydrogen(H), oxygen(O), and nitrogen(N), the elements that make up air and water in the natural world, in developing new materials with these properties. The first trial was conducted on titanium based materials that easily absorb hydrogen. Instead of adding or increasing alloying elements to materials, the high performance and new function of the materials can be obtained through the process of hydrogenation and dehydrogenation. It presents a mezzoscopic structure, leading to an improvement in mechanical properties. The hydrogen treatments is useful for the development of new functional materials. In the next trials, oxygen and nitrogen will be used to enhance the performance and function of materials based on simple elements compositions that are easier to recycle.
