Abstract Synthesis, characterization and density functional theory calculations have been combined to examine the formation of the Zr3(Al1–xSix)C2 quaternary MAX phases and the intrinsic defect processes in Zr3AlC2 and Zr3SiC2. The MAX phase family is extended by demonstrating that Zr3(Al1–xS...

(C re d it: C re d it: R ad ov ic a nd B en ite z; T A M U .) T he term “MAX phases” was coined in the late 1990s and applies to a family of 60+ ternary carbides and nitrides that share a layered structure as illustrated in Figures 1 and 2. They are so called because of their chemical formula: Mn+1AXn —where n = 1, 2, or 3, where M is an early transition metal, A is an A-group element (specific...

Thanks to their refractoriness, carbides are sensed as fuel coating for the IV generation of reactors. Among those studied, the Ti3SiC2 ternary compound can be distinguished for its noteworthy mechanical properties: the nanolamellar structure imparts to this material some softness as well as better toughness than other classical carbides such as SiC or TiC. However, under irradiation, its behav...

AZ91D magnesium composites reinforced by Ti3SiC2 MAX phase were fabricated the stir casting technique. Tensile tests reveal that effects of and Ti2AlC on Mg matrix are different. Unlike Ti2AlC-AZ91D composite for which delamination happens during fracture, Ti3SiC2-AZ91D fractures interfacial debonding mechanisms. Transmission electron microscopy characterization shows few nanometric grains form...

To enhance the absorption performance of silicon carbide fiber (SiCf), hybrid fibers with a double shell structure (Ti3SiC2 and carbon nanotubes (CNTs)) on SiCf ([email protected]3SiC2@SiCf) were successfully synthesized by combination molten salt method floating catalytic chemical vapor deposition. A series 10% weight fraction reinforced paraffin samples was prepared to study coating influence...

Ti3SiC2-SiC multilayer film coatings synthesis was investigated with the high temperature reactive chemical vapor deposition technique. The method consists of a reaction between SiC (as substrate and interlayers) H2-TiClx gaseous mixture. Cross-section morphologies phases were studies by scanning electron microscopy (SEM), X-ray diffraction (XRD) automated crystal orientation mapping in transmi...
