1. Co-firing complex biomass in a CFB boiler : ash transformation, corrosion control and materials selection
Abstract : The effects of greenhouse gas net emissions on global warming, stricter legislation on waste handling, and the pursuit of ever cheaper heat- and power production are all important factors driving the introduction of complex fuels in incineration plants. However - without fundamental knowledge regarding ash transformation, corrosion control, and materials selection – this introduction of potentially economically and environmentally beneficial fuels, might instead cause economic loss and environmentally adverse effects.

2. Alloy Design and Optimization of Mechanical Properties of High-Entropy Alloys
Abstract : 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. READ MORE

3. Aluminium alloy development for Additive Manufacturing
Abstract : Powder Bed Fusion (PBF Additive Manufacturing AM have emerged as a promising manufacturing process possessing a powerful combination of characteristics. Most noticeable are the near-net-shape, short lead time and flexibility, both with regard in design freedom and in part-to-part variation. READ MORE

4. Alloy Design and Characterization of γ′ Strengthened Nickel-based Superalloys for Additive Manufacturing
Abstract : Nickel-based superalloys, an alloy system bases on nickel as the matrix element with the addition of up to 10 more alloying elements including chromium, aluminum, cobalt, tungsten, molybdenum, titanium, and so on. Through the development and improvement of nickel-based superalloys in the past century, they are well proved to show excellent performance at the elevated service temperature. READ MORE

5. Numerical simulation of weldment creep response
Abstract : In-service inspections of high temperature pressureequipment show that weldments are prone to creep and fatiguedamage. It is not uncommon that severely damaged weldments arefound even before the design life of the component has beenreached. READ MORE
