1. 1. Machine learning for the prediction of duplex stainless steel mechanical properties : Hardness evolution under low temperature aging

   University essay from KTH/Materialvetenskap

   Author : Baptiste Giard; Sofia Karlsson; [2021]
   Keywords : Duplex Stainless Steel DSS; Machine Learning; Phase Separation; Me- chanical Properties; Alloying; Duplexa rostfria stål; Maskininlärning; Fasseparation; Mekaniska Egenskaper; Legering;

   Abstract : Duplex stainless steels, DSS are stainless steels that consist of the two phases austenite and ferrite.  The DSS have superb properties and are widely used in industries such as nuclear power and in pressure vessels, pipes and in pipelines.  The use of DSS are limited due to embrittlement which occurs at temperatures from 250 to 550 oC.
