Abstract [en]

The main objective of this master’s thesis,” Development of an improved method to steer powder properties“, is to analyze data and explain statistically how two magnetic parameters Hc and Com deviate from their expectation after sintering and pressing. Recently it has been noticed that it is difficult to maintain product tolerances after sintering. The reason is that the properties of the final product can deviate by quite a lot. The deviance can depend upon a number of factors such as sintering furnace, position in furnace, furnace load, etc. All this makes powder production hard to control. A multivariate analysis has been performed on Hc and Com measurements mode during powder manufacture in order to understand how they are affected by different factors. Multivariate analysis results proved that some factors have a considerable effect on Hc and Com so that the properties of a manufactured product can be undesirable. Final Developed models were consistent and probably can be used to control powder production. However, testing of acquired models accuracies are suggested.
