Method for improving the behavior of crack growth in titanium Alloys

摘要

Method for improving the behavior of crack growth in titanium Alloys.Includes: (a) build the material at a temperature between 14jc and 30jc, above the transit to BBB, to produce the recrystallization; b) Cooling the material through the transit temperature to BBB,At a Speed between 11jc (20jf) and 55jc (100jf per minute); (c) thermally treating the material at a temperature between 28 C and 8 C below the transit to BBB; (d) to cool The Alloy you have 6 to SW, 2, 4 and 6 Mo Ti ZR and 82,At a Speed greater than or equal to that produced by the air cooling and stabilize the Alloy for 2 to 10 hours at a temperature between 482jc (900jf) and 649jc (1.200jf).
