Microstructural and Mechanical Investigation of WC-TiC-Co
WC-Co cemented carbide is one of the widely hard materials used for cutting in machining industry due to its microstructural and mechanical stability even at high temperature. However diffusion wear is the most serious problem that WC-Co suffers from. One of the most applied approaches to improve the WC–Co cemented carbide performances is the addition of transition metal carbides such as

Influence of Gelatin Hydrogel Porosity on the
We investigated the influence of the porosity of the growth medium on the crystallization of calcium carbonate in hydrogels with different gelatin solid contents (2.5 5 and 10 wt ). In all experiments the precipitate consisted of calcite with occasional occurrences of some vaterite and aragonite. The calcite grew as compact radial intergrowths of crystals that show rhombohedral external
