Abstract
In this work it will be demonstrated that the excess energy created during mechanical alloying ( MA ) yielded alloying of couples with even possitive mixing enthalpy, As a result the new ternary CaMg2X ( X = V, Fe ) bcc alloy was successively synthesized by MA. It will be pointed out that the structural relation to the CaMg2 Laves phase with bcc-element was important issue to form the ternary bcc phase. In this work hydrogen solubility of the synthesized bcc alloy was determined in order to clarify the above issue on the structure and hydrogenation.
