  1. 1. Bone and Aluminium

    Author : Hans-Olov Hellström; Karl Michaëlsson; Hans Mallmin; Olle Svensson; Uppsala universitet; []
    Keywords : Surgery; Aluminium; Osteoporosis; Hip fracture; Osteoporotic fracture; Alzheimer´s dementia; Bone mineral density; Bone mineral content; Mortality risk; Biomechanics; Inductively coupled mass spectrometry; Kirurgi;

    Abstract : Osteoporosis is a major health care problem, by reason of its devastating consequences, in particular hip fractures. Worldwide it has been estimated that the incidence of hip fracture will increase to more than 6 million per year by 2050 compared to 1.7 million per year in 1990. READ MORE

  2. 2. Characteristics of cast aluminium-silicon alloys : microstructures and mechanical properties

    Author : Salem Seifeddine; Birger Karlsson; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Aluminium; Mocrostructure; Porosity; Tensile properties; Modelling; Chemical process and manufacturing engineering; Kemisk process- och produktionsteknik; Aluminium; microstructure; porosity; tensile properties; modelling.; Materials science; Teknisk materialvetenskap;

    Abstract : Applications of aluminium alloys are spreading in many industrial fields due to the excellent combination of castability, mechanical performance and lightness assured by such material. This project aims to establish a methodology in bringing the foundry process closer to the casting designer, and thereby leading to a more reliable and more optimised design. READ MORE

  5. 5. Rheocasting of aluminium alloys : Process and components characteristics

    Author : Mostafa Payandeh; Anders E. W. Jarfors; Magnus Wessén; Helen Atkinson; Högskolan i Jönköping; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rheocasting; aluminium alloy; RheoMetal TM process; microstructural characteristics; component properties and performance; robust design process;

    Abstract : Semi-Solid Metal (SSM) casting is a promising technology offering an opportunity to manufacture net-shape, complex geometry metal components in a single operation. However, the absence of foundry guidelines and limited design data for SSM casting makes it challenging to predict the performance of both process and components. READ MORE
