1. Influence of matrix and alloying on the high cycle fatigue properties of compacted graphite iron for cylinder heads
University essay from KTH/HållfasthetsläraAbstract : 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. READ MORE

2. Utvärdering av Sennebogen 830E och Svetruck TMF 12/9 vid rundvirkesterminal : en analys mellan två maskinsystem
University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)Abstract : Syftet med arbetet var att jämföra timmerhanteringsmaskinerna Svetruck TMF 12/9 och Sennebogen 830E. De studerades under de förutsättningar som fanns inom en rundvirkesterminal, där timmerhanteringsmaskinerna analyserades som två olika maskinsystem. READ MORE

3. 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)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

4. Material parameter study for aheavy-vehicle exhaust manifoldusing the finite element method : to increase component lifetime and decrease its environmental impact
University essay from Linköpings universitet/KonstruktionsmaterialAbstract : The thesis originates from a need to meet stricter environmental regulations for Scania, to reduce fuel consumption and emission from heavy-vehicles. Scania aims to fulfil these requirements by increasing combustion pressure and temperature. These conditions are tougher for the engine components and they shorten their lifetime. READ MORE

5. Effect of dwell time on stress intensity factor of ferritic steel for steam turbine applications
University essay from Linköpings universitet/Mekanik och hållfasthetsläraAbstract : In the transition from conventional to green energy production resources, steam turbines are used to satisfy the lack of energy during peaks in the demand times and the limited access of renewable resources. This type of usage for steam turbines makes them operate on a flexible schedule, which leads to unpredictable issues related to shorter component life and faster crack propagation. READ MORE
