6. Aspects of creep-fatigue in gas turbine hot parts
Sammanfattning : The goal is reliable creep-fatigue lifing methodology for industrial gas turbines.A literature study on high temperature materials used in gas turbines reveals that:• Most testing/modelling work has focused on characterisation and modelling of material response in isothermal standard tests, i.e. creep, tensile and LCF tests.

7. Microanalysis of a ferritic steel intended for high temperature applications
Sammanfattning : .... LÄS MER
8. Creep aspects of softwood from the cell-wall level to structures
Sammanfattning : This thesis addresses the intricate mechanical behaviour of natural materials, with a particular focus on wood. Despite millennia of use, understanding the mechanical behaviour of wood materials remains challenging due to their complex microstructures. LÄS MER
9. Influence of Segregants on Creep Fracture in Powder Metallurgical Martensitic Stainless Steel
Sammanfattning : This thesis deals with the behaviour of segregants in Powder Metallurgical (PM) 10%Cr steel and their impact on creep fracture. Particular interest is taken in determining the reaction products involved in creep cavitation and how these are connected to the powder surface reactions during the gas atomisation and consolidation (hot isostatic pressing).

10. Mechano-sorptive Creep in Wood - Experimental Studies of the Influence of Material Properties
Sammanfattning : Mechano-sorptive creep deformations appear when wood is loaded under varying moisture conditions. These creep deformations are known to be larger than the creep deformations under constant humidity conditions. The present thesis deals with mechano-sorptive creep in Norway spruce wood. LÄS MER
