TL;DR: In this article, three different processes have been applied to extract the natural hydroxyapatite: thermal decomposition, subcritical water and alkaline hydrothermal processes, and the results obtained by many physiochemical analyses have indicated that all the utilized methods have the ability to eliminate the organic compounds present in the bovine bones.

TL;DR: In this paper, subcritical water and alkaline hydrolysis methods are proposed methodologies for extraction of natural hydroxyapatite bioceramic from bovine bone.

TL;DR: In this article, friction stir-induced diffusion bonding is used for joining sheets of 5754 aluminum alloy to coated high strength steels (DP600 and 22MnB5) by promoting diffusion bonding in an overlap configuration.

TL;DR: In this article, the behavior of compacted graphite cast iron at elevated temperatures was examined to help facilitate its increased use in high temperature applications, and the tensile strength at elevated temperature was found to increase linearly with increasing nodularity % and pearlite %.

TL;DR: In this paper, various methods of producing compacted graphite iron (CGI) were investigated and the process parameters affecting the mechanical properties and microstructures of CGI were studied, including chemical composition, holding time, temperature and thickness of the casting.
