Abstract
Precipitates of Al2Ti with three different stacking sequences have bee n observed in Fe-modified L1(2)-type ordered Al3Ti specimens. Two of t he stacking sequences have been observed previously. The third type of Al2Ti, Al2TiIII, is identified in this study using conventional and h igh-resolution transmission electron microscopy (TEM). The Al2Ti preci pitates form as plates along {100} planes and compression tests perfor med at liquid N temperature show microcracks occurring along those {10 0} planes. The Al2Ti phase is believed to be responsible for the low c leavage strength that is observed.
