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

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

   Sammanfattning : 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.

   Sammanfattning : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. LÄS MER

4. 3. Implementering av 3D-scanning-teknik för kvalitetskontroll : En fallstudie hos Hitachi AB

   Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

   Författare :Hakan Taskin; Philip Sanderson; [2022]
   Nyckelord :3D-scanning; automatisering; digitalisering; FARO; Hitachi Energy; kvalitets- kontroll;

   Sammanfattning : Hitachi Energy is a world leading company in the production and installation of power transformers and the quality of their services is of the utmost importance. The majority of the company's current quality control methods are performed manually, the purpose of this study is to identify potential areas where the use of 3D-scanning technology as a method for quality control has potential, making use of interviews, literature studies and document analysis to do so.

   Sammanfattning : Ore characterization studies are of great importance to the mining industry, especially when dealing with precious metals by-products. It is a way towards increasing mining efficiency. LÄS MER

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

   Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

   Författare :Rasmus Fredheim; [2021]
   Nyckelord :;

   Sammanfattning : 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.
