1. Experimental and Numerical Investigation of the Quenching Process on Rotary Hollow Cylinder by Multiple Impinging Jets
Sammanfattning : The worldwide competitive market on metal products with higher quality in industry has increased the need to implement more advanced and controllable quenching techniques in the hardening stage of the heat treatment process. Moreover, sustainability and energy efficiency are key factors to consider in the development of advanced quenching techniques. LÄS MER
Sammanfattning : Medium Mn steels (~ 3–10 mass % Mn), a new category of advanced high strength steels, attracted worldwide research interests recent years due to their excellent mechanical properties and low cost. These steels have fine microstructures and contain large fraction of metastable retained austenite (~ 30 volume %), therefore exhibit excellent strength and elongation. LÄS MER
3. Effects of manufacturing chain on mechanical performance : Study on heat treatment of powertrain components
Sammanfattning : The increasing demands for lightweight designs with high strength call for improved manufacturing processes regarding heat treatment of steel. The manufacturing process has considerable potential to improve the mechanical performance and to obtain more reliable results with less variation. LÄS MER
4. Water mist fire protection systems : The development of testing procedures for marine and heritage applications
Sammanfattning : Modern, commercial water mist fire protection system technology evolved at the beginning of the 1990s due a need to replace halon fire-extinguishing systems and improve fire safety on passenger ships. This thesis documents the unknown water mist system development work by two Swedish companies during the 1970s and 1980s. LÄS MER
