TL;DR: In this article, the microstructures and elemental distributions of the joint cross-section as well as the reaction products at the ceramic/filler interface were analyzed using SEM, EDS, XRD and XPS.

TL;DR: In this paper, a sol-gel process was proposed for the preparation of continuous fibers by adding polyols containing 3-6 carbon atoms into anhydrous ethanol, adding aluminum powder and a catalyst after the mixture is evenly mixed and ensuring the mixture to react under the conditions of continuous stirring and reflux condensation under certain temperature to obtain transparent aluminum alkoxide solution.

TL;DR: In this paper, the authors proposed a connecting method for tungsten, copper and alloy thereof, which comprises the following steps: first, processing the surface of tengsten metal and performing surface treatment; plating nickel to the tungststen metal, processing and cleaning the copper alloy; and finally, overlapping and assembling the tengststen and the copper to form weldment, and connecting the weldments in a vacuum chamber through pressure diffusion welding to form a connecting piece.

TL;DR: In this article, the deformation behavior of a 20Cr-25Ni superaustenitic stainless steel (SASS) with initial microstructure of columnar dendrites was investigated using the hot compression method at temperatures of 1000-1200°C and strain rates of 0·01-10 s−1.

TL;DR: In this article, a method for the preparation of compact silicon carbide ceramics is described, which is characterized in that the compact accumulation among silicon carbides crystalline particles is realized so as to obtain a polycrystalline block ceramic with high compactness.
