Özet

In this study, static strain ageing behavior of commercially available and solution heat treated duplex stainless steel was investigated and the effect of static strain ageing on the mechanical properties was also determined in detail. Some of as-received duplex stainless steel test specimens were pre-strained in tension by 5% and then aged at 100 degrees C, 200 degrees C, 300 degrees C, 400 degrees C, 500 degrees C and 600 degrees C for 30 min in furnace. Some of duplex stainless steel test specimens were solution heat treated at 1050 degrees C for 30 min, water quenched and then pre-strained for 5% in tension shortly after the solution heat treatment.
