Overview of Intermetallic Sigma ( 𝜎 ) Phase Precipitation in

Barcik [] reported on the precipitation behavior of the 𝜎 phase in Cr-Ni austenitic stainless steel.His study found that the precipitated order of the 𝜎 phase was in triple point: 𝛿-ferrite, incoherent twin boundary, and inclusion grain.Sikka pointed out that the 𝜎 phase was easy to precipitate at the 𝛿 / 𝛾 interphase boundaries [] because the 𝛿 / 𝛾 interphase was a ...
