6. Microstructural development in laser-based powder bed fusion - from ferritic stainless steel to medium entropy alloys
Abstract : Ever since the advent of additive manufacturing (AM), the interest in AM technologies has skyrocketed due to its intrinsic ability to produce near net shaped components. Laser-based powder bed fusion (LB-PBF), being one of the most widely adapted AM technologies, has been especially a game changer due to its ability to produce components of complex geometries with improved designs and to reduce not only the final weight of the products but also the amount of the waste produced.

7. Microstructure engineering of additively manufactured materials by powder bed fusion-laser beam: Cases for ferritic stainless steels and medium entropy alloys
Abstract : Powder bed fusion laser beam (PBF-LB) is a powder bed fusion additive manufacturing process that is one of the most established and widely used techniques for manufacturing near net shape components. The unique characteristics of PBF-LB, such as the high cooling rates and local directional heat transfer, lead to the formation of unique microstructures. READ MORE

8. Multiscale modeling of atomic transport phenomena in ferritic steels
Abstract : Defect-driven transport of impurities plays a key role in the microstructure evolution of alloys, and has a great impact on the mechanical properties at the macroscopic scale. This phenomenon is greatly enhanced in irradiated materials because of the large amount of radiation-induced crystal defects (vacancies and interstitials). READ MORE

9. Deposit Induced Corrosion in Biofuel Combustion
Abstract : Deposit induced corrosion is one of the main mechanisms for attack on heat exchangers in biofuel boilers. This severe corrosion decreases the obtainable steam temperature in boilers, thereby the efficiency in production of electricity is reduced. Deposit formation from the gas on superheater tubes are is generally referred to as fouling. READ MORE
