16. High-Temperature Corrosion Chemistry in Oxy-Fuel Combustion
Sammanfattning : Drastic cuts in global CO2 emissions are needed to mitigate the global warming if limiting global warming to 2ºC. The power generation sector is largely based on fossil fuels and produces a significant share of the global CO2 emissions. LÄS MER
17. Microstructure and mechanical properties of low-temperature hot isostatic pressed Ti-6Al-4V manufactured by electron beam melting
Sammanfattning : Ti-6Al-4V manufactured by electron beam melting Keywords: Additive manufacturing, high-temperature tensile properties, low cycle fatigue, neutron diffraction, fatigue crack growth ISBN: 978-91-89325-27-2 (Printed) 978-91-89325-26-5 (Electronic) Ti-6Al-4V is the most widely used α+β titanium alloy in aerospace engine applications due to its high specific strength. Typically, the alloy is manufactured as castings or forgings and then machined to final geometry. LÄS MER
18. Entropy-stabilized transition metal diborides for high-temperature applications
Sammanfattning : Ultra-high temperature ceramics (UHTCs) are on the cutting edge as structural or protective materials that can withstand extreme environments such as hypersonic vehicles, nuclear reactors, and advanced turbine engines. These materials stand out for their melting temperatures above 2500 °C, high chemical stability, and retained mechanical resistance at temperatures higher than 1650 °C. LÄS MER
19. Thermal post-treatment of Alloy 718 produced by electron beam melting
Sammanfattning : Additive manufacturing (AM) has emerged as a disruptive technology and it is a vital part in the present era of fourth industrial revolution, Industry 4.0. LÄS MER
20. Synthesis of Transition Metal Aluminides from Elemental Powder Mixtures
Sammanfattning : Structural components such as those used in gas turbines for energy conversion applications, are subjected to high loads at elevated temperatures. In order to ensure that the components survive under these conditions for a sufficiently long time, it is imperative to select materials with good high temperature properties like strength and corrosion resistance.
