The local mechanical properties of ferritic and austenitic domains in a duplex stainless steel are locally studied by nanoindentation. The elastic and plastic properties of the two phases are determined. Without any specific surface treatment (chemical or electrochemical), the austenitic and ferritic domains present in the duplex stainless steel are distinguished using magnetic force microscopy. The magnetic scans allow nanoindentation results to be assigned to the respective phase, yielding… 

Study of Micro Deformation of Austenitic-Ferrite Duplex Stainless Steel by Nanoindentation Method

Based on the technology of the nanoindentation, the basic mechanical properties and cyclic deformation behavior of the austenite phase and ferrite phase in an austenitic-ferritic duplex stainless

Novel Mechanical Characterization of Austenite and Ferrite Phases within Duplex Stainless Steel

The microstructure and micromechanical properties of the constitutive phases of a particular duplex stainless steel in various processing conditions have been characterized. Hardness (H), elastic

A Comparative Study on the Cyclic Behavior of Austenite/Ferrite Phases Characterized by the Nanoindentation

The cyclic deformation behavior of the austenite and ferrite phase in an austenite-ferrite duplex stainless steel was studied by using the load-controlled cyclic nanoindentation approach. The results

Effect of the Temperature in the Mechanical Properties of Austenite, Ferrite and Sigma Phases of Duplex Stainless Steels Using Hardness, Microhardness and Nanoindentation Techniques

The aim of this work is to study the hardness of the ferrite, austenite and sigma phases of a UNS S32760 superduplex stainless steel submitted to different thermal treatments, thus leading to

Nanoindentation Characterization of Mechanical Properties of Ferrite and Austenite in Duplex Stainless Steel

The mechanical properties of as-cast and hot-forging duplex stainless steel samples with the same compositions were characterized by nanoindentation. The effect of surface treating method and working

Influence of Microstructure on the Mechanical Properties and Localized Corrosion of a Duplex Stainless Steel

The alloy studied, U50, is a ferritic-austenitic duplex stainless steel. In addition to the two major phases (that is, ferrite and austenite), several additional phases form during low and
