Solid-solution strengthening effect of vanadium addition to iron-modified L1{sub 2} titanium trialuminides
- Tokyo Univ. of Agriculture and Technology (Japan)
Two types of aluminum-titanium-iron-vanadium (Al-Ti-Fe-V) quaternary intermetallic compounds have been prepared by arc melting under argon atmosphere. Their compositions were nominally Al{sub 66}Ti{sub 25}Fe{sub 6}V{sub 3} and Al{sub 66}Ti{sub 25}Fe{sub 3}V{sub 6}. These alloys are based on the iron-modified titanium trialuminide with L1{sub 2} cubic structure. Vanadium addition up to about 6 mol% did not destroy the cubic symmetry, and L1{sub 2} solid solution compounds were produced in these two Al-Ti-Fe-V quaternary alloys. Microstructure and mechanical properties have been investigated. It has been demonstrated that vanadium addition to iron-modified L1{sub 2} titanium trialuminides can enhance their strength.
