Corrosion Behaviour of High-Mn TWIP Steels with Electroless Ni-P Coating
An attempt has been taken to improve the corrosion resistance of twinning-induced plasticity (TWIP) steels (Fe-25Mn and Fe-25Mn-3Al) by electroless Ni-P coating. Corrosion resistance in 3.5% NaCl and 0.1M H2SO4 solutions was characterized by the potentiodynamic polarization curves and Tafel method calculations. It was found that Ni-P coating improved the corrosion resistance by the factor of 4 ...
متن کاملPlastic strain due to twinning in austenitic TWIP steels
Twinning induced plasticity steels are austenitic alloys in which mechanical twinning is a prominent deformation mode, and which exhibit exceptional combinations of ductility, work hardening and ultimate strength. The authors develop in the present paper a crystallographic theory to enable the quantitative investigation of the role of mechanical twinning in enhancing the properties of these all...
متن کاملInfluence of High Strain Rates on the Mechanical Behavior of High-Manganese Steels
In this work, dynamic mechanical properties of three high-manganese steels with TRIP/TWIP or fully TWIP characteristics are studied. High strain rate experiments in the range of true strain rates between ~500 and 1800 /s are conducted using a dynamic torsional testing setup. All the three steels show a positive strain rate sensitivity in the intermediate range of strain rates (up to 500 /s). Bu...
متن کاملMechanical Behavior of TWIP Steel in High Strain Rate Torsional Test
Advanced high strength steels (AHSS) have recently attracted great attention because of their superior mechanical properties. A modern group of these steels, known as twinning induced plasticity (TWIP) steels, shows a unique combination of strength and ductility even at high rates of strain. In order to examine the functionality of such steels in dynamic loading conditions, their mechanical beh...
متن کاملErratum to: Description of full-range strain hardening behavior of steels
Mathematical expression describing plastic behavior of steels allows the execution of parametric studies for many purposes. Various formulas have been developed to characterize stress strain curves of steels. However, most of those formulas failed to describe accurately the strain hardening behavior of steels in the full range which shows various distinct stages. For this purpose, a new formula...
