ANALYSIS OF SHEAR WAVE ACOUSTIC VELOCITY IN 2205 DUPLEX STAINLESS STEEL

We report on the ultrasonic measurements of crystallographic texture in a solution treated 2205 duplex stainless steel aged isothermally at 700 deg C and 900 deg C for different time intervals. Texture measurements were performed by shear wave birefringence. Evidence is found of changes in the veloc...

Zusammenfassung:We report on the ultrasonic measurements of crystallographic texture in a solution treated 2205 duplex stainless steel aged isothermally at 700 deg C and 900 deg C for different time intervals. Texture measurements were performed by shear wave birefringence. Evidence is found of changes in the velocity of the fast mode of shear wave as aging time increases while the velocity of the slow mode of shear wave remains unaffected. The corresponding microstructure of aged specimens was observed and impact toughness was measured. Comparison is made with measurements of ferrite content for the two temperatures and different aging times.
