Yttrium aluminate glass microspheres with the eutectic composition 76.8 mol. % Al2O3 and 23.2 mol. % Y2O3 were prepared by combining the sol-gel Pechini method with flame synthesis. The sol-gel method was applied to achieve the desired composition homogeneity of the prepared glass and hence, improve the microstructure homogeneity and mechanical pro...
Novel high temperature-resistant thermal barrier coatings are urgently required as the stringent operating environment. High temperature property studies of zirconia matrix thermal barrier coatings doped with Cr3+, Mg2+, Si4+, and Mn4+ ions prepared by solid phase reaction method are reported. The results of X-ray diffraction measurements prove the...

Face-centered cubic (fcc)-phase high-entropy alloys (HEAs) have attracted much academic interest, with the stacking fault energy (SFE) playing an important role in regulating their mechanical behaviors. Here, we revealed the principles for regulating both the elastic and plastic behaviors by composition modification and Mo addition in an fcc-phase ...
The current printable materials are mainly limited to Fe, Ti, Co, and Ni-based alloys because they have good laser absorptivity. However, a number of Al alloys that are highly reflective to a laser are incompatible with selective laser melting. We demonstrate here that the coating with a small amount of high laser-absorbing Ni on Al powder reduces ...

Achieving good electrical properties and ductility of polymer semiconductors has always been challenging. In this work, a series of isoindigo derivative-based conjugated polymers was studied in an effort to gain a better understanding of the influence of polymer main and side chain structures on their electrical and mechanical properties. The resul...
High quality TiN coated 316L stainless steel can hardly be fabricated by the traditional chemical vapor deposition (CVD) methods because of the formation of HCl (g) corrosive byproduct and phase transformation at high deposition temperature. To address the problem, herein, for the first time a novel TiCl2 precursor is proposed to fabricate TiN coat...

Austenitic high-Mn steels present a dominant deformation mechanism of TWinning Induced Plasticity (TWIP) or TRansformation Induced Plasticity (TRIP), which effectively enables be used for various cryogenic applications. This mechanism affects significantly tensile or impact properties, and can be carefully tuned by adjusting alloying compositions; ...
