1. 1. In-situ Reduction by Incorporating H2 Filled Hollow Glass Microspheres in PM HIP Capsules

   University essay from KTH/Materialvetenskap

   Author : Emil Strand; [2018]
   Keywords : Hot isostatic pressing; hollow glass microspheres; powder metallurgy; oxide reduction; surface oxides; hydrogen;

   Abstract : 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).

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

   University essay from Institutionen för kemi - Ångström

   Author : Olof Sandin; [2013]
   Keywords : ;

   Abstract : 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®. READ MORE
