1. 1. Microstructure and Mechanical Investigation ofCarbides Particles Reinforced High AusteniticManganese Steel

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Abderrahim Ait ouakrim; [2023]
   Keywords : Metal Matrix Composites MMCs ; Manganese steel; Carbides particles; Wear resistance;

   Abstract : The objective of this study was to produce a metal matrix composite (MMC). This compositematerial proves highly suitable for scenarios involving abrasive wear, owing to the exceptionalhardness of carbide particles, in conjunction with the remarkable ductility and capacity for workhardening found in Hadfield steel.

5. 4. Infrared Curing of Glass Fiber Composite Tube : Optimization of the curing cycle

   University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

   Author : Rasmus Fredheim; [2021]
   Keywords : ;

   Abstract : This thesis has investigated the possibility of optimizing curing time by changing the energy source from a conventional oven to infrared radiation (IR) and if it is possible to achieve similar results as the company's current production of glass fiber composite tubes.   Many different parameters (time, temperature, heating rate, and rotation speed) might influence a cured composite tube's properties.

6. 5. A Geometallurgical Approach Towards the Correlation Between Rock Type Mineralogy and Grindability: A case study in Aitik mine, Sweden

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Raoul Schmitt; [2021]
   Keywords : Geometallurgy; autogenous grinding; process mineralogy; grindability test; abrasion breakage; automated mineralogy;

   Abstract : Aitik is a large copper porphyry type deposit located in northern Sweden, currently exploited at an annual rate of approximately 45Mt. The ore's exceptionally low head grade of 0.22 % Cu and varying degrees of hardness across the entire deposit pose challenges to the two fully autogenous grinding lines, each of which comprises a 22.
