1. 1. The Effect Of Sub Tx Heat Treatments On The Magnetic Properties Of An Fe-based Bulk Metallic Glass

   University essay from Uppsala universitet/Materialfysik

   Author : Grunditz Jakob; [2022]
   Keywords : Bulk metallic glass; annealing; heat treatment; MOKE; Magnetic; Fe-based; Coercivity; Magnetic properties; Magnetic saturation; coercivity; saturation; magnetic coercivity; sub crystallization; sub Tx; Relaxation;

   Abstract : Metallic glasses produced with Selective Laser Melting (SLM) often contain internal mechanic stress. This internal stress can have an impact on the magnetic properties of the material due to its connection to the magnetic anisotropy of the material. READ MORE

3. 2. Effect of post-treatment of cemented carbide : Microstructural investigation and evaluation of mechanical properties of cemented carbide inserts for rock tool applications

   University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

   Author : Jessica Jacobs; [2021]
   Keywords : ;

   Abstract : Cemented carbides are used in rock tool applications by reason of their beneficial mechanical properties, i.e. a combination of high toughness, wear resistance and hardness. The cemented carbides commonly receive their hardness from tungsten carbides (WC) whereas cobalt (Co) is the dominating binder material. READ MORE

4. 3. FE based method for simulation of rock-loading on a truck

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Tamim Kohestani; Ali Zeaiter; [2019]
   Keywords : FEM; Rock loading; Nastran; LS-DYNA; ANSA; META; Contact; Linear; non-linear; Explicit; Implicit.;

   Abstract : Volvos trucks are used to carry boulders of varying sizes from different mining sites or construction sites. These boulders are loaded onto the dumper of the truck by a wheel-loader which drops the boulders from various heights causing an impulse like force which distributes throughout the frame and to the rest of the truck.

5. 4. Development of a modern catalytic system for the production of C3+ aliphatic alcohols by the Fischer-Tropsch method

   University essay from KTH/Energiteknik

   Author : Aravind Ganesan; [2019]
   Keywords : syngas; Cobalt; Fischer-Tropsch; alcohols; hydrocarbons; syngas; kobolt; Fischer-Tropsch; alkoholer; kolväten;

   Abstract : This thesis deals with converting a mixture of H2 and CO, also referred to as syngas or producer gas, to higher or mixed alcohols and other fuels through a process called Fischer Tropsch Synthesis (FTS). It is a beneficial pathway that minimizes the dependence on oil and similar fossil fuels which contribute to rapid climate change by releasing harmful greenhouse gases. READ MORE

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

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

   Abstract : 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. READ MORE
