Structural Examination of Cold Rolled M316 Austenitic Stainless Steel.

摘要

The structures of solution treated and cold worked M316 austenitic steel have been investigated using magnetic measurements, optical and transmission electron microscopy and electron, X-ray and neutron diffraction. The results show that the steel is resistant to both eta and alpha'-martensite formation during ambient temperature rolling to deformations of up to 50% and this is attributed to its relatively high stacking fault energy. The banded structures observed in the cold worked steel have been positively identified by electron diffraction and high resolution dark field techniques as deformation twins. (Author)
