1. 6. The Effect of Solidification time and Cooling rate on the Ultimate tensile Strength of Grey Cast Iron.

   University essay from KTH/Materialteknologi

   Author : Dinesh Sundaram; [2018]
   Keywords : Lamellar graphite iron; tensile properties; pearlitic properties; cooling rate; solidification time; Magmasoft.;

   Abstract : 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. READ MORE

3. 7. Experimental Study of Metallic Surfaces Exposed to Cavitation

   University essay from KTH/Materialvetenskap

   Author : Marcio Freitas De Abreu; [2018]
   Keywords : cavitation; cylinder liner; lamellar gray cast iron; erosion pitting; graphite class; cavitation;

   Abstract : Cylinder liners in heavy-duty truck engines are subjected to intense vibrations and may sustain damage from the cavitation of bubbles in the coolant liquid, with some risks of leakage and engine breakdown. An ultrasonic oscillating probe was used to simulate the pitting rates and behavior of samples extracted from cylinder liners, which are made of grey cast iron, with differences in surface roughness, glycol and inhibitor content in coolant, coolant temperature and graphite flake class; bainitic microstructures were also tested.

4. 8. Tribological evaluation of the contact between upper compression ring and cylinder liner with different surface coatings

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

   Author : Pär Wassborg; [2016]
   Keywords : piston ring; cylinder liner; wear; friction; grey cast iron; titanium oxide; chromium oxide;

   Abstract : The constant pursuit in the automotive industry to increase the engines performance, new solutions are always developed and tested to reduce the friction and increase the efficiency in the engine. One component that contributes to friction losses is the piston ring pack where the top compression stands for up to 40 %. READ MORE

5. 9. AUTOMATIC BRAKING DISC ANALYSIS SYSTEM

   University essay from Mälardalens högskola/Akademin för innovation, design och teknik

   Author : Joakim Gustafsson; [2015]
   Keywords : automatic; braking disc; analysis; eddy current; non destructive testing; NDT; truck;

   Abstract : Volvo Group Truck Technology has the ambition to automate parts of their routine service. Therefore a project was launched to investigate which parts of the routine that could be automated. The idea of this project is to lower the time spent on the service and also improve the working environment for the personnel. READ MORE

6. 10. Relations between the performance of a coated cutting tool and the composition and properties of the wear resistant coating : A study including first principles modeling, mechanical properties and technological testing

   University essay from Materialteori; Institutionen för kemi - Ångström

   Author : Maria Bryngelsson; [2013]
   Keywords : Thin film; coating; wear; density functional theory; first principles; ab initio; turning;

   Abstract : This thesis work was performed at AB Sandvik Coromant and aimed to enhance the knowledge about the relationships between the performance of TiN and TiAlN-coated cutting tools in metal turning and their mechanical and chemical properties. Measurements of coating material properties and turning wear tests in annealed tool steel Sverker 21, stainless steel 316L, grey cast iron V314 and nodular cast iron SS0727 were performed. READ MORE
