The defining feature of high-entropy alloys (HEAs) is their unprecedented degree compositional inhomogeneity which influences dislocation movements. We demonstrate differences between a HEA (Fe 40 Mn Co 10 Cr ) and conventional solution alloy (316L stainless steel) using acoustic emission (AE) spectroscopy. AE measurements under tension show the coexistence two avalanche processes in Fe HEA, wh...

316L stainless steel is a commonly used material in range of industries, including the automotive and aerospace due to its advantageous mechanical properties, such as high yield strength outstanding corrosion resistance. In recent years, use metal additive manufacturing technologies for fabricating has become more common, it permits creation intricate geometries that are difficult achieve throu...

Type 316L stainless steel particles were pseudo-sensitized by being heated at 700 degrees C for 100 h under a reduced pressure of 1.3 x 10(-3) Pa. Pseudo-sensitization treatment resulted in the formation of chromium-rich precipitates at the outermost surfaces of the stainless steel particles. The curve for the apparent surface charge density (sigma app) of the pseudo-sensitized particles showed...

In this investigation, Ti/TiN nanolayer and TiN single layer coatings were coated on substrate of AISI 316L stainless steel by applying physical vapor deposition (PVD) using the type of cathodic arc evaporation (CAE). The evaluation of microstructure were carried out using x-ray diffraction (XRD), nanoindentation, atomic force microscopy (AFM) as well as scanning electron microscopy (SEM). Pola...

A coupled phase field and crystal plasticity model is established to analyze formation of dislocation structures residual stresses during rapid solidification additively manufactured 316L stainless steel. The work focuses on investigating the role microsegregation related intra-grain cellular microstructure 316L. Effect shrinkage considered along with mediated plastic flow material solidificati...

Palladium-based membranes are attractive for their nearly perfect permselectivity to hydrogen. Membrane modules, consisting of a membrane foil, porous stainless steel substrate, test frame and flange were assembled and tested in an electrically heated vessel. Instantaneous hydrogen permeation flux was measured. Influences of operation conditions on the membrane performance were examined. Micros...

The stress corrosion cracking (SCC) of 316L stainless steel manufactured by laser powder bed fusion (LPBF) was investigated slow strain rate tests in 6 wt% FeCl3. effects build orientation and surface roughness on the SCC LPBF were also investigated. LBPF revealed higher uniform elongation compared to wrought 316L. Specimens tested perpendicular direction showed a greater susceptibility SCC, wi...

Compositionally graded cylinders comprising FeCo-2V, a soft magnetic alloy, and 316L stainless steel, were produced by directed energy deposition incorporating two different gradient lengths. Five distinct regions in the microstructure observed both as-printed annealed gradients. When normalized for length, gradients showed similar grain size microhardness profiles. In tensile tests, samples fa...
