Deformation Induced Martensite in an AISI 301LN Stainless Steel: Characterizati...
Abreu, Hamilton Ferreira Gomes de; Carvalho, Sheyla Santana de; Lima Neto, Pedro de; Santos, Ricardo Pires dos; Freire, Válder NogueiraIn austenitic stainless steels, plastic deformation can induce martensite formation. The induced martensite is related to the austenite (γ) instability at temperatures close or below room temperature. The metastability of austenite stainless steels increases with the decreasing of stacking fault energy (SFE). In this work, the deformation induced martensite was analyzed by X ray diffraction, electron back scatt...
Effect of high temperature annealing on texture and microstructure on an AISI-4...
Abreu, Hamilton Ferreira Gomes de; Costa, Antonia Daniele Souza Bruno; Tavares, Sérgio Souto Maior; Santos, Ricardo Pires dosAISI 444 is a Mo-alloyed ferritic stainless steel which presents good naphthenic corrosion resistance, making it attractive for applications in petroleum refining plants; however, good formability is also important. To achieve good formability with this alloy the annealing process is crucial. The annealing temperature in ferritic stainless steel is usually around 850 °C, which falls in the range of sigma phase ...
