Introduction
Embarking on a thesis project at Scania offers a unique opportunity to bridge academic knowledge with practical industry applications. This project not only provides a platform to engage in cutting-edge research but also serves as a step for future professional endeavours. Many professionals in the field have launched their careers through similar thesis projects, establishing valuable connections and gaining hands-on experience that is highly regarded in the industry.
Background
Fuel system components in common rail diesel engines suffer from fatigue due to high fuel pressures (>2000 bar) used in the fuel systems. Often used material and processes today as to increase the fatigue strength for critical components in the fuel system are clean steel and carburization. At recent years low pressure carburizing (LPC) is common alternative to gas-carburizing at atmospheric pressure, one advantage being more environmentally friendly as it produces much less carbon monoxide. In addition, the surface characteristics become different with less surface oxidation generated in LPC which means higher carburizing temperatures can be used and hence less process time.
Fatigue properties of carburized steel can vary significantly as results of variations in alloying and processing interactions that produce large variations in the carburized microstructure. In association to material, process parameters and the resulting microstructure and residual stresses developed in carburization, the fatigue properties also relate to the mechanisms behind fatigue crack initiation and fatigue crack propagation. This Master thesis work is intended to explore this topic through laboratory bending testing of carburized steel and advanced microscopy.
Objectives
• Perform bending fatigue testing on atmospheric and low-pressure carburized specimens.
•Use of both conventional and novel analysis methods such as EBSD for microstructural characterization of the two different carburizing processes. X-Ray will be used to characterize the residual stresses.
•Use of different fractographic analysis methods for characterization of the fatigue cracking mechanisms of tested specimens.
Practicalities
The prospective candidate should preferably have basic knowledge in materials technology and microstructural analysis. The project will involve experimental work and analysis using advanced characterization techniques.
Education/program/focus
The prospective candidate should be pursuing a Master’s degree in Material Science, Mechanical Engineering, Physics, or a related field.
