1. 6. 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. 7. Self Lubricating Components

   University essay from Uppsala universitet/Institutionen för teknikvetenskaper

   Author : Simon Tidén; Niklas Levin Bjärnlid; Tim Melin; Daniéla Quist; Filip Selenius Larsson; [2017]
   Keywords : self lubricating; solid lubricant; high speed steel; powder metallurgy; friction; wear; molybdenum disulfide; tungsten disulfide; hexagonal boron nitride; soft metals; copper;

   Abstract : The tribological and mechanical properties are of great importance for a material’s lifetime, since it is highly dependent on these two factors. The purpose of this report was to examine suitable solid lubricants for Erasteel, a company that manufactures hot isostatic pressed high speed steels, that will enhance the tribological properties of their steels without worsening the mechanical properties.

5. 9. CFD Analysis of Cold Stage Centrifugal Pump for Cooling of Hot IsostaticPress with Validation Case Study

   University essay from KTH/Mekanik

   Author : Shane Hereford; [2017]
   Keywords : CFD; HIP; Quintus Technologies; Centrifugal pump; pump curve;

   Abstract : Hot isostatic pressing (HIPing) has been a growing material treatment process for performance part manufacturingfor over 50 years. This process of using an inert gas at high temperature and pressure to densifymaterials leads to vastly improved material properties by removing pores and other micro- aws. READ MORE

6. 10. Gradient formation in cemented carbides with 85Ni:15Fe-binder phase

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Niklas Larsson; [2015]
   Keywords : cemented carbide; alternative binderphase; sintering; gradient; hard metal;

   Abstract : In today’s inserts used for metal cutting the binder phase consists of cobalt (Co).However, EU’s REACH programme and the U.S’s National Toxicity Programme(NTP) classified Co as toxic/carcinogenic. Therefore, there is a strong need toinvestigate alternative binder phases. READ MORE
