  1. 1. Heat treatment of Al-Si-Cu-Mg casting alloys

    University dissertation from Göteborg : Chalmers Reproservice

    Author : Emma Sjölander; Högskolan i Jönköping.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast aluminium alloys; Heat treatment; Solution treatment; Artificial ageing; Tensile properties; Plastic deformation; Microstructure; Modelling; Plastic Deformation; Tensile Properties; Heat Treatment; Solution Treatment; Artificial Ageing;

    Abstract : Environmental savings can be made by increasing the use of aluminium alloys in the automotive industry as the vehicles can be made lighter. Increasing the knowledge about the heat treatment process is one task in the direction towards this goal. The aim of this work is to investigate and model the heat treatment process for Al-Si casting alloys. READ MORE

    Abstract : Modern IC-engines produce more power per displaced volume and operate at higher combustion pressures and temperatures. In addition, engine structure materials such as aluminium and magnesium alloys, which are more sensitive to thermal loads, are more commonly used. READ MORE

  5. 5. Heat treatment of solid wood effects on absorption, strength and colour

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Dennis Johansson; Luleå tekniska universitet.; [2008]

    Abstract : Wood is a useful construction material, but it has less desirable properties such as poor durability and poor dimensional stability. These problems can be reduced by using various chemical treatments. Increased environmental awareness has raised the demand for more environmentally friendly methods. READ MORE
