Influence of hydrogen on deformation and fracture mechanisms in austenitic steel types

چکیده
In the present work, hydrogen/material interaction with two austenitic steel types, created via a completely different alloying strategy, is investigated. The steels include 304L stainless (ASS) and 18Mn-0.6C twinning-induced plasticity (TWIP) steel. Constant extension rate tensile tests are performed to evaluate influence of hydrogen on deformation fracture mechanisms. A reference condition without compared seven days electrochemically precharged condition. ASS shows transformation α’-martensite hydrogen, while increases fraction additionally enables ε-martensite. surface has transgranular, quasi-cleavage appearance. TWIP twinning abundant ε-martensite observed in presence hydrogen. type intergranular due high cracking sensitivity grain boundaries.

متن کاملPlastic Deformation Influence on Intrinsic Magnetic Field of Austenitic Biomaterials
This article deals with non-destructive evaluation of austenitic stainless steels, which are used as the biomaterials in medical practice. Intrinsic magnetic field is investigated using the fluxgate sensor, after the applied plastic deformation. The three austenitic steel types are studied under the same conditions, while several values of the deformation are applied, respectively. The obtained...

In this study, the hot deformation processing map of AISI 304 austenitic stainless steel in two initial grain sizes of 15 and 40 μm was investigated. For this purpose, cylindrical samples were used in the hot compression test at the temperature range of 950-1100 °C and the strain rate of 0.005-0.5% s-1. At first, the relationship between the peak stress and Zener-Hollomon parameter w...
