1. 16. Relation Between the Material in Press Hardening Dies and Fully Martensitic Transformation : Sheet properties of thick 3D-sheets in small series production

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Jesper Christensson; [2020]
   Keywords : hot stamping; press hardening; material properties;

   Abstract : This report evaluates the influence of the die material on the cooling rate and martensitic transformation of press hardened sheets. The goal was to increase the thicknesses of sheets that can form fully martensitic microstructure when press hardened. READ MORE

3. 17. INFLUENCE OF CARBON CONTENT AND COOLING CONDITIONS ON THE THERMAL CONDUCTIVITY AND TENSILE STRENGTH OF HIGH SILICON LAMELLAR GRAPHITE IRON

   University essay from Jönköping University/JTH, Material och tillverkning

   Author : Gokul Ram; Vishnu Harikrishnan; [2020]
   Keywords : Lamellar cast iron; hypereutectic; eutectic; hypoeutectic; carbon; silicon; carbon equivalent; cooling rate; dendrites; graphite flakes; specific heat capacity; thermal expansion coefficient; thermal diffusivity; thermal conductivity; tensile strength; hydraulic diameter.;

   Abstract : Much study has been carried out to determine the properties of Lamellar Graphite Iron (LGI) or grey iron and their relations to factors such as the cooling rate, the dendrite morphology, the pouring temperature, and so on. However, there hasn’t been much comprehensive study on the properties of LGI outside the generally used and accepted composition, with 1 to 3% Silicon. READ MORE

4. 18. Identifying Constraints in Available Production Capacity

   University essay from Lunds universitet/Produktionsekonomi

   Author : Kristin Egerström; Louise Landin; [2020]
   Keywords : Production planning · Production equipment limitations · Constraint management · Theory of Constraints · Single Minute Exchange of Die · Overall Equipment Effectiveness · Toolset capacity; Technology and Engineering;

   Abstract : Accurate production scheduling is an essential element to obtain high performing manufacturing facilities. By optimally allocating the available resources in a factory, improved equipment utilization, and hence production efficiency, can be reached. READ MORE

5. 19. Development of a Method to Measure Residual Stresses in Cast Components with Complex Geometries

   University essay from KTH/Materialvetenskap

   Author : Yang Yang; [2020]
   Keywords : Residual Stresses; Cast Iron; Engine Components; XRD; Ultrasonic; Cutting;

   Abstract : Cast iron, taking the advantages of the advanced castability forming components of complex geometries and favorable mechanical properties, is employed in engine components in truck industries. Compacted graphite iron (CGI) integrates both merits of lamellar graphite iron (LGI) and spheroidal graphite iron (SGI) such as good machinability and high thermal conductivity from LGI, high ultimate tensile strength (UTS), good fatigue resistance, high elastic modulus, and high ductility from SGI, thus is now becoming a competitive alternative of traditional LGI in cylinder blocks and heads.

6. 20. Influence of nitrocarburization on the thermomechanical fatigue properties of ductile iron for exhaust components : Analysis and comparisons of TMF-properties

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Karl Larsson; [2019]
   Keywords : Thermo-mechanical fatigue; low cycle fatigue; thermal strain; ductile cast iron; nitrocarburizing;

   Abstract : New stricter environmental legislation requires lower emissions and fuel consumption of automotive engines. Therefore the fuel efficiency must be increased but this leads to higher loads in the engine. As for the exhaust system it is affected by higher thermomechanical loads. READ MORE
