1. Plastic Deformation of Duplex Stainless Steel
Sammanfattning : Duplex austenitic/ferritic stainless steels are increasingly used as an alternative to conventional austenitic grades. Main advantages of the duplex grades are good resistance to corrosion cracking and corrosion fatigue in environments that contain chloride. LÄS MER
2. Deformation Behaviour of Near Fully Pearlitic Railway Steels During Monotonic and Cyclic Loading
Sammanfattning : The main conclusions that could be drawn from the present work are that the deformation behaviour of fully and near fully pearlitic steels is very similar and that a combination of low temperature, prestraining and high deformation rates is critical for the performance. This was shown from microscopy studies, tensile, impact and low cycle fatigue (LCF) testing. LÄS MER
3. Microstresses and anisotropic mechanical behaviour of duplex stainless steels
Sammanfattning : The evolution of deformation during monotonic and cyclic loading of a two-phase material like duplex stainless steel is more complex than in a single-phase material. One reason for this is the microstresses formed due to differences in thermal and mechanical properties between the two phases. LÄS MER
