AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
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 ...
Single crystals of ferromagnetic shape memory alloys (MSMA) exhibit magnetic field and stress induced strains via energy dissipating twinning. Embedding single crystalline MSMA particles into a polymer matrix could thus produce composites with enhanced ene ...
The crystallography of martensite formed in 0.2C-2.0Mn-1.5Si-0.6Cr steel was studied using the electron backscattered diffraction (EBSD) technique. The results showed that the observed orientation relationship (OR) was closer to that of Nishiyama-Wasserman ...
Structural components used in civil engineering applications are often subjected to compressive loads. Unlike the tensile strength of fiber-reinforced polymer (FRP) materials, their compressive strength is resin-dominated, exhibiting lower values and more ...
A 'one-step' theory based on Pitsch distortion is proposed to explain the continuity between the orientations of the Kurdjumov-Sachs (KS), Nishiyama-Wassermann (NW) and Pitsch variants observed on the electron backscatter diffraction pole figures of marten ...
The crystallography of martensite formed in 0.2C-2.0Mn-1.5Si-0.6Cr steel was studied using the EBSD technique. The results showed that the observed orientation relationship was closer to the Nishiyama- Wassermann (N-W) than to the Kurdjumov-Sachs (K-S) ori ...
In this work, mechanical spectroscopy (internal friction) is used for a qualitative evaluation of interstitial carbon content in martensite and of the dislocation density in bulk samples of quenched and tempered steel. On one hand, the decrease of the ampl ...
We investigate continuous axial rotation as a mechanism for extending the reach of an elastic rod injected into a horizontal cylindrical constraint, prior to the onset of helical buckling. Our approach focuses on the development of precision desktop experi ...
Bhadeshia recently claimed that the two-step theory of martensitic transformation was mathematically incorrect and incapable of making predictions about the observed pole figures. The present paper argues that his comments are not justified and that his al ...
