1. Modelling mechanical properties by analysing datasets of commercial alloys
Sammanfattning : Commercial alloys are continuously developed to improve their performance. Therefore it is important to develop new optimisation software, which could be used in development of new materials or in materials selection. In this study the mechanical properties which are important in materials selection in mechanical design are investigated. LÄS MER
2. Hardening Distortions of Serial Produced Gears
Sammanfattning : Hardening distortions are unwanted changes in shape and dimension that arise during hardening of steel components. Uncontrolled distortions induce random errors to the manufacturing process, and have a strong negative impact on manufacturing costs. LÄS MER
3. Secondary hardening in some low-chromium hot-work tool steels
Sammanfattning : Low-chromium hot-work tool steels combine good heat conductivity with excellent tempering resistance. This property combination has made these steels ideal for die casting and extrusion. LÄS MER
4. Wear in cone crusher chambers
Sammanfattning : Cone crushers are widely used in the mining and aggregates industries to reduce the size of blasted rock. A cone crusher consists of a fixed conic liner called concave and inside it a smaller moving liner called mantle. The mantle is suspended on an eccentrically rotating shaft. LÄS MER
5. 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
