説明
<jats:title>Abstract</jats:title><jats:p>Two types of aluminum–titanium–iron–vanadium ( Al–Ti–Fe–V ) quarternary intermetallic compounds have been prepared by arc melting under argon atmosphere. Their compositions were nominally Al<jats:sub>66</jats:sub>Ti<jats:sub>25</jats:sub>Fe<jats:sub>6</jats:sub>V<jats:sub>3</jats:sub> and Al<jats:sub>66</jats:sub>Ti<jats:sub>25</jats:sub>Fe<jats:sub>3</jats:sub>V<jats:sub>6</jats:sub>. These alloys are based on the iron–modified titanium trialuminide with L1<jats:sub>2</jats:sub> cubic structure. Vanadium addition up to about 6 mol% did not destroy the cubic symmetry, and L1<jats:sub>2</jats:sub> solid solution compounds were produced in these two Al–Ti–Fe–V quarternary alloys. Microstructure and mechanical properties have been investigated. It has been demonstrated that vanadium addition to iron–modified L1<jats:sub>2</jats:sub> titanium trialuminides can enhance their strength.</jats:p>
