Abstract This paper presents a comprehensive study on the strain-induced martensitic transformation and reversion of martensite in AISI 304 stainless steel using number complementary techniques such as dilatometry, calorimetry, magnetometry, in-situ X-ray diffraction, coupled with high-resolution microstructural transmission Kikuchi diffraction analysis. Tensile deformation was applied at temperatures between room temperature 213 K (−60 °C) order to obtain different volume fraction (up ~70...
The process of palladium(II) chloride complex ion adsorption on activated carbon was investigated. influence variable parameters such as the initial concentration Pd(II) (from 0.04 to 2.25 mmol·kg–1) and temperature 294 348 K) determined. Experiments were conducted in solution with pH equal 0 1. It found that Freundlich isotherm describes better than Langmuir model. observed sorption capacity high q294K = 42.4 mg·g–1 q323K 67 for at 323 K, it is increasing increase. obtained results showed...
In-situ monazite Th–U–total Pb dating and zircon LA–ICP–MS depth-profiling was applied to metasedimentary rocks from the Vaimok Lens in Seve Nappe Complex (SNC), Scandinavian Caledonides. Results of dating, coupled with major trace element mapping monazite, revealed 603 ± 16 Ma Neoproterozoic cores surrounded by rims that formed at 498 10 Ma. Monazite rim formation facilitated via dissolution–reprecipitation monazite. The record garnet growth as they are depleted Y2O3 respect cores. Rims...
In this work, we report the synthesis method of carbon quantum dots (CDs) using one-step for fast and effective metal ion determination. Ascorbic acid was used as an inexpensive environmentally friendly precursor. High-pressure high-temperature reactors were purpose. Microscopic characterization revealed size CDs in range 2–6 nm they had ordered structure. The photoluminescence properties depend on process temperature, obtained highest PL spectra 6 h hydrothermal reaction. maximum emission...
Abstract The crystal structure and transformation path from austenite to 10M martensite in Ni–Mn–Ga single are examined employing high‐energy synchrotron radiation, scanning, transmission electron microscopy. Using temperature gradient, an austenite/twinned interface is stabilized revealing the microstructure of both phases sequence across interface. Depending on distance interface, three distinct types lattice, namely simple tetragonal two monoclinic modulated ones, that is, 10M′ confirmed....
Currently, new technologies for catalyst synthesis the production of green energy are being sought. Platinum-based materials particular interest due to their unique catalytic properties. In this work, a one-step bimetallic Pt–Pd@ACF (ACF = activated carbon fibers) in microreactor system was demonstrated. For purpose, glass applied, and synthesized catalysts were analyzed using following techniques: spectrophotometry, TEM, SEM, DLS, XRD, MP-AES (microwave plasma atomic emission spectroscopy)....
Pattern matching approaches to electron backscatter diffraction (EBSD) in the scanning microscope (SEM) provide qualitatively new possibilities for microstructural analysis of chiral non-centrosymmetric phases due influence dynamical effects on formation EBSD Kikuchi patterns.

We identify characteristic intra-grain inversion domains different handedness which are well-known from classical...
We summarize a data analysis approach for electron backscatter diffraction (EBSD) which uses high-resolution Kikuchi pattern simulations to measure isochoric relative deformation gradient tensors from experimentally measured patterns of relatively low resolution. Simulation-based supersampling the theoretical test enables significant precision improvement tensor parameters obtained in best-fit determinations strains and orientations low-resolution experimental patterns. As an application, we...

Orientation determination does not necessarily require complete knowledge of the local atomic arrangement in a crystalline phase. We present method for microstructural phase discrimination and orientation analysis phases which there is only limited crystallographic information available. In this method, experimental Kikuchi diffraction patterns are utilized to generate self-consistent master reference use technique Electron Backscatter Diffraction (EBSD). The experimentally derived data...
Inconel 718 is a precipitation strengthened, nickel-based super alloy of interest for the Additive Manufacturing (AM) low volume, complex parts to reduce production time and cost compared conventional subtractive processes. The AM process involves repeated rapid melting, solidification reheating, which exposes material non-equilibrium conditions that affect elemental segregation subsequent formation phases, either beneficial or detrimental. These variations are difficult characterize due...
