Electronic structure investigation of MAX- phases by soft x-ray emission spectroscopy
The electronic structure of nanolaminate Ti2AlC and Ti2AlN thin films, so-called MAX-phases, were investigated by soft X-ray emission spectroscopy. These nanolaminated carbide and nitride compounds represent a class of layered materials with a combination of properties from both metals and ceramics. The bulk-sensitive soft X-ray emission technique is particularly useful for detecting detailed e...
متن کاملSynthesis and Characterization of New MAX Phase Alloys
This Thesis explores synthesis and characterization of new MAX phase alloys (M = early transition metal, A = A-group element, and X = C or N), based on incorporation of M and X elements previously not considered. My primary focus is on M = Mn for attaining magnetic properties, and on X = O for potential tuning of the transport properties. A recent theoretical study predicted (Cr1-xMnx)2AlC MAX ...
متن کاملInvestigation of Ti2AlC and TiC by soft x-ray emission spectroscopy
The electronic structure of the MAX-phase Ti2AlC was investigated by soft x-ray emission spectroscopy. This nanolaminated carbide compound represents a class of layered materials with a combination of properties from both metals and ceramics. The bulk-sensitive soft x-ray emission technique is shown to be particularly useful for detecting detailed electronic structure information about internal...
متن کاملStructure of a new bulk Ti5Al2C3 MAX phase produced by the topotactic transformation of Ti2AlC
Upon annealing cold-pressed Ti2AlC, -325 mesh powders, at 1500 °C for 8 h in argon, the resulting partially sintered sample contained 43(±2) wt.% of the layered ternary carbide Ti5Al2C3. Herein, the X-ray powder diffraction pattern of Ti5Al2C3 is reported for the first time. Its structure and stoichiometry are confirmed through high-resolution transmission electron microscopy. This phase has a ...
متن کاملEFFECT OF FABRICATION PARAMETERS ON SYNTHESIS OF Ti2AlC AND Ti3AlC2MAX PHASES BY MASHS
Mechanically Activated Self-propagating High temperature Synthesis (MASHS) is the method which is used to promote self-propagating synthesis by increasing activity of reactants and increase the purity of products. In this study Ti 2 AlC and Ti3AlC2 max phases were synthesized by using mechanically activated self-propagating high temperature synthesis (MASHS) and samples reactivity and phase str...
