| Abstract: | This work, focuses on the spinodal decomposition mechanism study on the duplex stainless steel duplex UNS S31803, composed by austenite (c) and ferrite (a) phases, at 425 C and 475 C temperatures by ultrasonic speed measurements. This temperature range is responsible for the transformation mechanism of ainitial phase to a phases (poor in chromium) and a0 (rich in chromium) by spinodal decomposition. The techniques to accomplish this analysis are based mainly on X-ray diffraction measures and ultrasonic speed. The obtained results show that it is possible to conclude that the use of ultrasonic speed measurements indicates a promising technique for following-up the phase transformation and spinodal decomposition on the steel studied. |
