Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An alloy composition comprising aluminum, titanium, vanadium, zirconium, and niobium, said alloy composition existing essentially as a single phase having a body-centered cubic crystal structure. 
     
     
         2 . The alloy composition of  claim 1  consisting essentially of said aluminum, said titanium, said vanadium, said zirconium, and said niobium. 
     
     
         3 . The alloy composition of  claim 1  characterized by a calculated density of about 6.2 g/cm 3 . 
     
     
         4 . The alloy composition of  claim 1  characterized by an ultimate strength of at least about 1,413 MPa. 
     
     
         5 . The alloy composition of  claim 4  further characterized by yield strength of at least about 650 MPa. 
     
     
         6 . The alloy composition of  claim 1  characterized by an ultimate strength of at least about 1,680 MPa. 
     
     
         7 . The alloy composition of  claim 6  further characterized by yield strength of at least about 840 MPa. 
     
     
         8 . The alloy composition of  claim 1  characterized by a compressive ductility of at least 20 percent. 
     
     
         9 . The alloy composition of  claim 1  characterized by a compressive ductility of at least 25 percent. 
     
     
         10 . The alloy composition of  claim 1  characterized by a compressive ductility of at least 30 percent. 
     
     
         11 . The alloy composition of  claim 1  wherein said aluminum is present at about 1 to about 9 atomic percent. 
     
     
         12 . The alloy composition of  claim 1  wherein said titanium is present at about 25 to about 33 atomic percent. 
     
     
         13 . The alloy composition of  claim 1  wherein said vanadium is present at about 10 to about 33 atomic percent. 
     
     
         14 . The alloy composition of  claim 1  wherein said zirconium is present at about 5 to about 10 atomic percent. 
     
     
         15 . The alloy composition of  claim 1  wherein said niobium is present at about 25 to about 33 atomic percent. 
     
     
         16 . An article formed from the alloy composition of  claim 1 . 
     
     
         17 . An alloy composition comprising aluminum, titanium, vanadium, zirconium, and niobium, wherein a dominant phase of said alloy composition has a body-centered cubic crystal structure, and wherein said alloy composition is characterized by an ultimate strength of at least about 1,413 MPa. 
     
     
         18 . The alloy composition of  claim 17  consisting essentially of said aluminum, said titanium, said vanadium, said zirconium, and said niobium. 
     
     
         19 . The alloy composition of  claim 17  further characterized by a compressive ductility of at least 25 percent. 
     
     
         20 . An article formed from the alloy composition of  claim 17 .
