A method for forming titanium alloys is described comprising first forming an ingot that includes: (a) from about 5.5 to about 6.75 weight percent aluminum (preferably from about 5.75 to about 6.5 weight percent aluminum), (b) from about 3.5 to about 4.5 weight percent vanadium (preferably from abou

A method for forming titanium alloys is described comprising first forming an ingot that includes: (a) from about 5.5 to about 6.75 weight percent aluminum (preferably from about 5.75 to about 6.5 weight percent aluminum), (b) from about 3.5 to about 4.5 weight percent vanadium (preferably from about 3.75 to about 4.25 weight percent vanadium), (c) from about 0.2 to about 0.8 weight percent iron, (d) from about 0.02 to about 0.2 weight percent chromium, (e) from about 0.04 to 0.2 weight percent nickel, (f) from is about 0.004 to about 0.1 weight percent cobalt, (g) from about 0.006 to 0.1 weight percent niobium, (h) from about 0 to about 0.20 weight percent carbon, (i) from about 0.22 to about 0.32 weight percent oxygen, (j) from about 0 to about 0.1 weight percent nitrogen, the balance being titanium and unavoidable impurities, each impurity totalling no more than about 0.2 weight percent, with the combined weight of the impurities totalling no more than about 0.5 weight percent. The ingot is then processed to provide an .alpha.-.beta. alloy. A method for forming armor plates also is described. The method comprises forming an alloy according to the general methods described. The alloy is then fashioned into armor plates.
