3. 2. Long term aging and creep exposure for advanced heat resistant alloys : A phase analysis

   University essay from Uppsala universitet/Institutionen för materialvetenskap; Uppsala universitet/Institutionen för kemi - Ångström

   Author : Daniel Lundberg; Filip Wilson; Hjalmar Gunnarsson; Leo Sjörén; Robin Xu; Erik Djurberg; [2021]
   Keywords : Austenitic stainless steel; ferritic steels; nickel based alloys; creep; ageing; XRD; SEM EDS; LOM;

   Abstract : This project was ordered by Sandvik Materials Technology and was performed by a group of students at Uppsala university. The purpose of the project was to study precipitation behavior and structure stability in six advanced heat resistant alloys. Each sample were subjected to a creep rupture test in 600 or 700°C depending on the alloy type. READ MORE

4. 3. LCA of Low-temperature District Heating Network Components

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Nils Olsson; [2021]
   Keywords : District Heating; LCA; Life Cycle Assessment; Pipes; Environment; Technology and Engineering;

   Abstract : Following the development of new materials and the continuous technical progress made in the construction and energy industries, district heating as a concept finds itself on the brink of a generational shift. One of the pioneering projects leading the way is the creation of Brunnshög, an modern and sustainable district under construction in the north-eastern end of the city of Lund, Sweden. READ MORE

5. 4. Researching and Developing Universal Gas Purging Solutions

   University essay from KTH/Maskinkonstruktion (Avd.)

   Author : Ludvig Briheim; Dennis Ståhl; [2020]
   Keywords : Gas Purging Plug; Pipe Purging; Root Shielding; Shielding Gas; Pipe Welding; Rotgasplugg; Rotgasskydd; Skyddsgas; Rörsvetsning; Rörrengöring;

   Abstract : In the welding of more sensitive metals such as stainless steel, titanium and some specific nickel alloys, the presence and application of a protective gas is essential. Without the use of a nonreactive shielding gas, defects occur in or adjacent to the weld joint, which vary from light discoloration of the weld bead to the direct onset and propagation of cracks.
