6. On constitutive modelling in metal plasticity
Sammanfattning : .... LÄS MER
7. 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
8. Monotonic and Cyclic Plastic Deformation of High-Strength Aluminium Alloys
Sammanfattning : Dynamic strain ageing (DSA) and dynamic precipitation (DP) are two, closely interrelated, phenomena arising from the dynamic interaction between mobile solute atoms and dislocations. The occurrence of DSA and DP is confined to specific ranges of strain rate and temperature, and aluminium alloys are generally prone to experience DSA and DP already at ambient temperatures and conventional strainrates.

9. Modeling and experimental characterization of large biaxial strains and induced anisotropy in pearlitic rail steel
Sammanfattning : Large shear strains accumulate in the near-surface region under the running band of railway rails. In this region, rolling contact fatigue cracks often initiate, causing major problems for the railway industry. LÄS MER
10. 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
