The elimination of the FexAly type phases was considered the solution to low ductility presented in aluminum-steel welded joints. Recently, the researches do not seek the suppression but the control of the thickness of these compounds. In this work, Al-Fe joints were manufactured by solid state and fusion welding, looking for controlling the formation of intermetallic comp...
In this article, the influence of various vacancy defects on the Young’s modulus of carbon nanotube (CNT) - reinforcement polymer composite in the axial direction is investigated via a structural model in ANSYS software. Their high strength can be affected by the presence of defects in the nanotubes used as reinforcements in practical nanocomposites. Molecular structural mechanics (MSM)/finite ...
Abstract: titanium sheets in pure molten aluminum at 750 and X-Ray Diffraction Analysis results, TiAlintermetallic layer thickness increases slowly at primary stages. After that an enhanced growth rate occurs due to layercracking and disruption. Presumably, reaction starts with solving titanium into the molten aluminum causing intitanium super saturation and TiAlintermetallic layer which conseq...
Background and aims: Hospital personnel are exposed to various occupational hazards because of their job circumstances. The aim of this study is to investigate the ergonomic problems of hospital from the perspective of human-system interface technology and to recommend the strategies for improvement. Methods: In this qualitative study, the conceptual framework of hospital ergonomic problems ...
