Morphological and Crystallographic Characteristics of alpha Structure in a Low-Carbon Iron-Nickel Alloy

Roland Logé, Cyril Cayron, Gaojun Mao, Rui Cao

The features of a (body-centered cubic) structures were investigated in a low-carbon multicomponent alloy from morphological and crystallographic perspectives. In addition to apparent features of granular bainite and lamellar martensite, a morphological si ...

Microstructural evolution and mechanical property development with nickel addition in low-carbon weld butt joints

Roland Logé, Cyril Cayron, Gaojun Mao, Rui Cao

Four metal powder flux-cored wires with added nickel (Ni) were designed to systematically investigate how Ni influences the microstructure and toughness in low-carbon bainitic weld metals (WMs). The microstructure was safely predicted by utilizing reasonab ...

The relationship between low-temperature toughness and secondary crack in low-carbon bainitic weld metals

Roland Logé, Cyril Cayron, Gaojun Mao, Rui Cao

This paper aims to reveal the relationship among low-temperature toughness, microstructure and secondary crack from both microstructural and crystallographic perspectives. Instrumented Charpy tests were carried out in the upper platform, transition tempera ...

Thermal activation parameters of plastic flow reveal deformation mechanisms in the CrMnFeCoNi high-entropy alloy

William Curtin, Céline Varvenne, Joël Bonneville

To reveal the operating mechanisms of plastic deformation in an FCC high-entropy alloy, the activation volumes in CrMnFeCoNi have been measured as a function of plastic strain and temperature between 77 K and 423 K using repeated load relaxation experiment ...

Variant selection in surface martensite

Roland Logé, Cyril Cayron, Annick Pauline Baur

A significant variant selection is reported in isothermal martensite formed on the surface of an Fe-30% Ni sample. The selection phenomenon is modelled using different descriptions of the martensitic phase transformation. In particular, matrices based on t ...

Characterization of the deformation and phase transformation behavior of VC-free and VC-containing FeMnSi-based shape memory alloys by in situ neutron diffraction

Helena Van Swygenhoven, Steven Van Petegem, Christian Leinenbach

The stress-induced fcc-austenite to hcp-martensite transformation in the iron based shape memory alloy (SMA) Fe-17Mn-5Si-10Cr-4Ni with and without VC precipitates is investigated by in-situ neutron diffraction measurements upon uniaxial loading and unloadi ...

In Situ Synchrotron X-Ray Diffraction and Small Angle X-Ray Scattering Studies on Rapidly Heated and Cooled Ti-Al and Al-Cu-Mg Alloys Using Laser-Based Heating

Helena Van Swygenhoven, Steven Van Petegem, Christian Leinenbach, Patrick Schloth

Beam-based additive manufacturing (AM) typically involves high cooling rates in a range of 10(3)-10(4) K/s. Therefore, new techniques are required to understand the non-equilibrium evolution of materials at appropriate time scales. Most technical alloys ha ...
