EFFECT OF HEAT TREATING MEDIA ON MECHANICAL PROPERTIES
Abstract
One-half in. diam Ti 6Al-4V and Ti 155A bar stock was heat treated in an air furnace and in salt bath furnaces containing Park Chemical Co., No. K-33 and E. F. Houghton Co., No. 235 heat treating salts. The Ti 6Al-4V was solution heat treated at 1650 F in the v-ous media for periods ranging 1 to 90 min; the Ti 155A was similarly heat treated at 1450 F. All specimens were machined subsequent to aging at 900 F for 6 hours; heat treat scale contamination thus was eliminated as a test variable. The test results indicated that 10 min salt bath and 20 min air furnace solution heat treatments could be used to produce acceptable mechanical properties; these times were in contrast with the generally recommended one hour solution heat treating time, and showed that the solution reactions in the titanium alloys tested were not extremely sluggish.
