1. Machinability study on GCI brake discs - Effects of material variations and process behavior on tool life
Uppsats för yrkesexamina på grundnivå, Lunds universitet/Industriell ProduktionSammanfattning : Grey cast iron is one of the most used materials in the automotive industry. The material has a range of properties that makes it suitable for machining applications, but manufacturers still experience machinability problems. LÄS MER
2. Influence of matrix and alloying on the high cycle fatigue properties of compacted graphite iron for cylinder heads
Master-uppsats, KTH/HållfasthetsläraSammanfattning : Continued improvements in combustion processes, introduction of biofuels, decreasing fuel consumption and increasing specific power will inevitably lead to an increase of the combustion pressure, which can be accompanied with a temperature increase. This will increase the loading on many components and drives the development of materials more resistant to the harsh conditions close to the engine. LÄS MER
3. INFLUENCE OF CARBON CONTENT AND COOLING CONDITIONS ON THE THERMAL CONDUCTIVITY AND TENSILE STRENGTH OF HIGH SILICON LAMELLAR GRAPHITE IRON
Master-uppsats, Jönköping University/JTH, Material och tillverkningSammanfattning : 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. LÄS MER
4. Development of a Method to Measure Residual Stresses in Cast Components with Complex Geometries
Master-uppsats, KTH/MaterialvetenskapSammanfattning : 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.

5. The Effect of Solidification time and Cooling rate on the Ultimate tensile Strength of Grey Cast Iron.
Master-uppsats, KTH/MaterialteknologiSammanfattning : Tensile strength modelling is usually done to predict the mechanical properties of lamellargraphite iron considering microstructural features. This work attempts to create a simplifiedmodel incorporating cooling rate and solidification time without considering themicrostructural features. LÄS MER
