1. Alloy Design for Refractory High Entropy Alloys with Better Balanced Mechanical Properties at Both Room Temperature and Elevated Temperatures
Sammanfattning : Motivated by the desire to improve the energy efficiency of gas turbines by operating them at higher temperatures (HT), which will contribute to a more energy efficient and carbonless society, the quest for novel ultrahigh-temperature materials can never be overwhelming. High entropy alloys, the recently emerged multi-component alloys with equiatomic or close-to-equiatomic compositions, are considered highly promising as next-generation ultrahigh-temperature materials.

2. Alloy Design and Optimization of Mechanical Properties of High-Entropy Alloys
Sammanfattning : High-entropy alloys (HEAs) are described as alloys containing multi-principal elements in equal or close to equal atomic percentage. HEAs are considered as potential structural materials for high-temperature applications; where alloy design and optimization of mechanical properties is extremely critical. LÄS MER
3. Al-Si Cast Alloys - Microstructure and Mechanical Properties at Ambient and Elevated Temperature
Sammanfattning : Aluminium alloys with Si as the major alloying element form a class of material providing the most significant part of all casting manufactured materials. These alloys have a wide range of applications in the automotive and aerospace industries due to an excellent combination of castability and mechanical properties, as well as good corrosion resistance and wear resistivity.

5. Microstructure Evolution and Mechanical Properties of Haynes 282
Sammanfattning : Precipitation-hardened nickel-based superalloys find wide applications in aero engines and land-based gas turbines due to a combination of properties such as high temperature strength, resistance to oxidation and corrosion, fabricability, and creep strength. Structural engine components are traditionally cast to achieve higher degree of geometrical design freedom. LÄS MER
