HEAT TREATMENT OF Mn-V-Mo AGE-HARDENING AUSTENITIC STEEL
Technical Report
·
OSTI ID:4184284
The age-hardening characteristics of Mn--V--Mo austenitic steels were determined as a function of the temperature of the solution treatment. The optimum condition for developing the full age-hardening pctential of an alloy is 1/2 hour at 2100 tained F followed by a water quench. Subsequent aging treatments required for maximum-hardness levels are: 1 hour at 1400 tained F, 6 hours at 1300 tained F, or 16 hours at 1200 tained F. An aging temperature between 1200 and 1300 tained F is optimum for controlling the balance between yield strength and ductility. The yield strength of metals in the fully-aged condition is directly proportional to Brinell hardness, at 80,000 to 150,000 psi for the compositions investigated. (auth)
