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 FC
