Ultrasound accelerate hydrogen-induce phase transformations in intermetallic compounds; magnetic field forms a texture in them. Al and Co decrease a stability of the LaNi5-хAlх-H2 (х=0,6; 0,8; 1,0 and 1,5) and LaNi5-хCoх (х=0,6; 0,8; 1,5 and 2,0) compounds in hydrogen. A texture is formed in LaNi3Co2 compound after HDDR process. A replacement of Zr by Ti in ZrCr2 leads to the increase of it stability in hydrogen and slowdown of the disproportionation reaction. A replacement of La by Nd in La1-xNdxNi3,5Al1,5 (х=0,1; 0,2) leads to the change of their disproportionation products in hydrogen. Possibility of application of hydrogen, as a medium and reagent, for the formation of nano- structure in functional materials is shown.
