A series of creep age forming FLASH LIFT BONDER INSIDE experiments were carried out on 7075 aluminum alloy with different prebending radii at 443 K for 10 h.The hardness, tensile properties and high cycle fatigue performance of the alloy after creep age forming were obtained.In addition, the microstructure and fatigue fracture of the alloy were obs
Background: Elderly patients have a high incidence of falls and injuries in hospitals due to various reasons.The aims of this study were to explore the characteristics and factors associated with fall injuries among elderly Haarspülung patients.Methods: A retrospective survey study was conducted.Data were retrieved from the patient safety reportin
One of the factors that can affect to the quality of lubricantion is metal particle content due to friction of engine parts.Metal particle in lubricanting oil could damage the engine parts, so it is neccessary to reduce the metal particle content which mingled in lubricant oil.The experiment was conducted in laboratory scale using power magnetic ty
Emerging high-entropy alloy (HEA) films achieve high strength but generally show ineludible brittle fractures, strongly restricting their micro/nano-mechanical and functional applications.Nanolayered (NL) CoCrFeNi/graphene composites are elaborately fabricated via magnetron sputtering and the transfer process.It is uncovered that NL CoCrFeNi/graphe
