 note = {We have demonstrated in our previous report that the excess energy created during mechanical alloying (MA) yielded alloying of couples with negative mixing enthalpy and the new ternary bcc phase was formed. It was noticed that the important issue there was the structural correlation between the Laves phase and bcc structures. The aims of this study is to synthesize LaA1_2 based bcc alloys in structural relation to the Laves phase structure with additive element V, and to clarify the above issue on the structure and hydrogenation. The parent materials used in this study were La1_2 and V metal powders. The MA was performed under Ar gas atmosphere and the rotation speed is 710 rpm. The ratio of powder to ball weight is 1: 40. The results are summarized as follows: 1) We could not synthesis the single bcc phase from 60 hours of MA. After 60 hours of MA, amorphous phase was formed. 2) From the TEM bright image observation，we have confirmed that the alloy is composed by nano size particles such as 20 nm of diameter of crystalline particles. 3) The TDS was used to measure the hydride properties of the synthesized powders. The results showed that hydrogen was not absorbed after hydrogenation treatment., application/pdf},
