21. Solid metal induced embrittlement of titanium alloys
Sammanfattning : Titanium alloys were for a time believed to be highly resistant to environmentally assisted cracking because of their ability to form a protective oxide film on the surface. Their resistance can still be considered to be high, but when cracking resistance was originally defined to ensure reliable functionality of fracture-critical components, certain conditions that promote cracking were discovered.

22. Al-Si Cast Alloys - Microstructure and Mechanical Properties at Ambient and Elevated Temperatures
Sammanfattning : Swedish industry is a global leader in development and manufacture of automotive and aviation components where the usage of aluminium products is remarkable. In addition to manufacturing aluminium components, casting enables low-cost and low-emission production of complex geometry components with a range of sizes. LÄS MER
23. Investigations of the corrosion resistances of magnetron sputtered multicomponent materials : A study on high entropy alloys, high entropy sublattice ceramics, and metallic glasses
Sammanfattning : The corrosion resistances of sputter deposited AlCrNbYZrN, CrNbTiTaWC and TaNiSiC alloys were assessed in acidic and alkaline environments. Compositionally complex alloying strategies, and whether they produced coatings with superior corrosion resistances, were explored. LÄS MER
24. Microstructure and mechanical properties of Ti-6Al-4V welds produced with different processes
Sammanfattning : Titanium alloys are widely used for components in the fan and compressor sections of aeroengines mainly because of their superior strength-to-weight ratio. Large static compressor components can be manufactured by welding together smaller subcomponents, which has potential to provide benefits such as higher buy-to-fly ratio and improved performance of the components.

25. Effect of high-pressure cooling on the residual stress in Ti-alloys during machining
Sammanfattning : Titanium alloys are widely used in aerospace industry but also in other industry sectors. Details for compressors used for generation and petrochemical plants and medical devices can be mentioned as a few examples. Plastic deformation during forming of the metals introduces residual stresses. LÄS MER
