1. 1. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

   Master-uppsats, Jönköping University/JTH, Material och tillverkning

   Författare :Anton Rolseth; [2023]
   Nyckelord :Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

   Sammanfattning : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. LÄS MER

3. 2. High temperature tribological evaluation of a self-lubricating laser cladding with and without external solid lubricant

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Cecilia Nemeth; [2020]
   Nyckelord :high temperature tribology; hot metal forming of aluminium; self-lubricating laser cladding; external solid lubricant;

   Sammanfattning : The purpose of the project work was to build knowledge of the tribological behaviour of self-lubricating laser cladding, with and without external solid lubricant during conditions relevant for hot metal forming of aluminium. The materials used during the project were plates coated with a Ni-based self-lubricating clad and a reference sample of work tool steel. LÄS MER

4. 3. Material Transfer Mechanisms during Interaction of Aluminium Alloy and Tool Steel at Elevated Temperatures

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Gabriel Macêdo; [2020]
   Nyckelord :material transfer mechanisms; high temperature tribology; hot metal forming tribology; hot-stamping of aluminium alloys; aluminium alloys;

   Sammanfattning : Hot stamping of aluminium alloys allows for increased formability, decreased springback and the possibility of integrating age-hardening heat treatments into the process. However, it can be challenging due to the occurrence of material transfer of aluminium onto the tool, as aluminium is prone to adhesion even at low temperatures. LÄS MER

5. 4. Self-Lubricating Properties of Laser Claddings for High Temperature Forming Processes

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Tugce Caykara; [2018]
   Nyckelord :self-lubricating; steel; aluminium; friction; wear; high temperature; hot forming;

   Sammanfattning : This thesis summarizes the work done on tribological characterization of multifunctional hardfacing coatings with self-lubricating properties, intended for use in mechanical components operating in high temperature applications for which conventional lubricants are no longer effective. Deposition techniques like laser cladding have a great potential in reworking/repair of high value industrial components in order to extend their lifetime. LÄS MER
