摘要
经5h的高能球磨，A175Ti25合金由铸态时的四方有序DO22结构转变为无序FCC过饱和固溶体；球磨60h后，仍保持FCC结构待态时具有立方有序L12结构的单相Al67Ti25Mn8合金，其结构随球磨时间的变化步骤为：有序FCC→无序FCC→FCC超微晶＋非晶→非晶．
Upon 5h of milling, the structure of stoichiometric Al3Ti transformed from the as-cast ordered DO22 to disordered FCC and remains unchanged till milling time of 60h. The structural evolution of Al67Ti23Mn8 alloy with ordered L12 was as follows: ordered FCC-disordered FCC→supersaturatedFCC solid solution＋partial amorphous→complete amorphous.
