1. 1. Microstructure-corrosion interrelations in new low-lead and lead-free brass alloys

   Master-uppsats, KTH/Materialvetenskap

   Författare :Emil Stålnacke; [2017]
   Nyckelord :Brass; dezincification; annealing; detrimental phases; heat treatment; microstructure;

   Sammanfattning : In new low-lead and lead-free brass alloys, it is not understood how the corrosion properties,such as dezincification, are related to material composition as well as annealing temperatureand duration. This study aims to fill this knowledge gap by mapping sixteen annealingconditions and three different brass alloy compositions to their respective microstructure anddezincification performance.

3. 2. Parameter study of a muffle furnace performance on powder heating using numerical multiphysics simulation with COMSOL

   Kandidat-uppsats, KTH/Materialvetenskap

   Författare :Emil Stålnacke; [2015]
   Nyckelord :muffle furnace; syngas; biomass; natural gas; parameter study; comsol; powder metallurgy; heat transfer;

   Sammanfattning : The muffle furnace main purpose is to anneal the rough sponge iron powder transported through it, which is done by burning natural gas. Heat is absorbed by the muffle and is transferred to the bed of sponge iron powder. LÄS MER
