1. Microstructural evolution during hot compression of a Ni-base superalloy: Dynamic and post-dynamic recrystallization below the secondary carbide solvus temperature
Abstract : With an increased demand to lower emissions, the eciency of aircraft engines have to be improved. One way to achieve this is to increase the operation temperature. However, due to the extremely challenging environments in the hot sections of these engines, the current alloys are at their limits. READ MORE

2. Structure and properties of thick plate and near surface properties after high speed machining af AA7010
Abstract : Using thick plates instead of forgings in the aircraft industry for integral construction of load carrying components is becoming more and more practice. The reasons are shorter lead-times from design of a modified or totally new component to introduction in an aircraft and smaller variations in properties for plate compared to forging. READ MORE

3. Microstructure and Fatigue Analysis of PM-HIPed Alloys : A Focus on Inconel 625 and High-Nitrogen Tool Steel
Abstract : Nickel-based superalloys and tool steels are well-known high-performance alloys due to their extensive use in many different industries. Nickel-based superalloys have found their way into aircraft, aerospace, marine, chemical, and petrochemical industries owing to their excellent high-temperature corrosion and oxidation resistance.

5. Microstructural characterization of Haynes 282 after heat treatment and forging
Abstract : Over the past 75 years, solid-solution strengthened superalloys have been one among the most widely used materials for long term applications at elevated temperatures. The combination of properties such as high temperature strength, resistance to oxidation and corrosion, fabricability, and creep strength make them an unusual class of materials, attracting researchers and scientists to explore its full potential.
