1. 1. Investigation Of Mechanical Properties And Microstructure Of Steel-Wires

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

   Författare :Khalifa Maissara; [2021]
   Nyckelord :steel; heat treatment; quenching and partitioning; quenching and tempering; retained austenite; wear mechanisms; wear testing;

   Sammanfattning : Wear and friction are among the major problems faced in several industries such as mining industry. This creates challenges to select better materials with good wear behavior in order to improve the service life of the components. LÄS MER

3. 2. Designing a Heat Treatment to Achieve Ductile Advanced High Strength Steels

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

   Författare :Abdellatif Laarich; [2020]
   Nyckelord :Heat treatment; Quenching and Partitioning; Austempering; Quenching and Tempering; High Aluminum Steel; Strenx 700MC; Ductility; Strength;

   Sammanfattning : Heat treatment is a way to significantly change materials properties. When presented with materials that lack certain mechanical properties, it is possible to change its chemical properties and microstructures by applying heat. This can help achieve better yield strength, ductility and toughness. LÄS MER

4. 3. Wear resistance of heat-treated Advanced High Strength Steels and casting

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

   Författare :Joan Morata Royes; [2020]
   Nyckelord :;

   Sammanfattning : The necessity to improve the durability of the machinery used in the milling industry has lead to several types of research. One study is focused on the plates that are located in the stationary and moving jaws of crushers to diminish particles sizes of Gneiss and Diabase rocks. LÄS MER

5. 4. The development of scanning X-ray diffraction phase mapping techniques using automated Rietveld refinements.

   Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Författare :Johannes Brask; [2018]
   Nyckelord :Retained austenite X-ray diffraction XRD Scanning X-ray diffraction SXRD; Physics and Astronomy;

   Sammanfattning : A methodology for determining inhomogeneities in microstructural features has been established using scanning X-ray diffraction (SXRD) and automated Rietveld refinements. The method has proven successful for spatially resolved quantitative phase analysis or "phase mapping" of retained austenite on a variety of martensitic steel samples, including carbon case-hardened steel bars and quenching and partitioning (Q&P) steel sheets.
