).Calculation shows that yttrium is on the fifth hybrid level and magnesium is on the third one in pure metal crystals.By comparing with aluminum in Mg-Al alloy,it is shown that the reason why the solution strengthening effect of yttrium is better than that of aluminum in Mg-Al alloy is the enhanced bond energy according to EET.And it is concluded from EET analysis that intermetallics Mg24Y5 can......
