This paper describes the influence of two-steps sintering regime temperatures concerning the final properties of titanium hydride based alloy obtaining by Two-Steps Sintering (TTS) route, which is a method that is part of the Powder Metallurgy (PM) technology. The initial titanium hydride powder has been mixed with some metallic powders as: Alumix, Mn, Zr, Sn and graphite was added in different proportions for improving the final mechanical properties. The Two-Steps Sintering (TTS) route have been applied for obtaining a low-cost Ti- alloy. The effect of the sintering regime temperatures on the height and diameter shrinkages and density for these alloys based on titanium hydride powder was studied
The paper presents the results of our research in the elaboration and characterization of composites type epoxy - textile fiber and vibration behaviour. These were made by pressing, and the textile fibers we tested were cotton, flax, hemp and wool. Starting from the dynamic response of composite beam with damping (which is in free vibration), there is established a way to determine the damping factor. There has been experimentally determined the damping factors for some samples: sample 1 – built from cotton; sample 2 – built from hemp; sample 3 – built from flax; sample 4 – built from whool.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
