    Sammanfattning : For many metal components the presence of hard, non-metallic inclusions such as oxides lowers the impact toughness by acting as fracture initiation points and easing crack propagation. In components produced by powder metallurgy hot isostatic pressing (PM HIP), oxides often form a continuous network of small, spherical inclusions after consolidation at the prior particle boundaries (PPB).

  2. 2. Optical and Mechanical Properties of Cool Roof Paint Containing Hollow Thermoplastic Microspheres

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för kemi - Ångström

    Författare :Olof Sandin; [2013]
    Nyckelord :;

    Sammanfattning : This master thesis examines the effect of hollow thermoplastic microspheres in coolroof paints. These types of paints are characterized by their high reflectivity forwavelengths up to 2.5 micrometers and high absorptivity in the IR region. Thethermoplastic microspheres were produced by Expancel®, a unit withinAkzoNobel®. LÄS MER
