Superelastic NiTi (51.0 at.% Ni) specimens reinforced with 0, 10 and 20 vol.% TiC particles were deformed under uniaxial compression while neutron diffraction spectra were collected. The experiments yielded in-situ measurements of the thermoelastic stress-induced transformation. The evolution of austenite/martensite phase fractions and of elastic strains in the reinforcing TiC particles and the...

The liquid metal embrittlement sensitivity of a low nickel 316 L austenitic steel has been studied with eutectic gallium indium alloy. case is firmly established this and by X-Ray fractography EBSD. Brittle to ductile recoveries were observed via dedicated parametric study (varying cross-head speed temperature). return ductility temperature strongly correlated significant reduction in plastical...

The trade-off between transformation-induced plasticity (TRIP) strengthening and the intrinsically brittle nature of deformation-induced ??-martensite (DIM) has been a long-standing dilemma in optimizing strength–toughness synergy austenitic steels. This limited their potential use, particularly energy absorption applications. Here, we propose new strategy to minimize negative effect without li...

Abstract Deformation mechanisms activated during tensile deformation of nanocrystalline NiTi wire in martensite state were investigated by combination two experimental methods: (i) analysis the evolution martensite-variant microstructures grains deformed TEM and (ii) texture situ synchrotron X-ray diffraction. The obtained results are linked to activity various twinning processes martensite. It...

The fatigue life of metals manufactured via laser-based powder bed fusion (L-PBF) highly depends on process-induced defects. In this context, not only the size and geometry defect, but also properties microstructure surrounding material volume must be considered. presented work, microstructural changes in vicinity a crack-initiating defect specimen produced L-PBF made AISI 316L were analyzed de...
