1. Toughness Enhancement in Hard Single-Crystal Transition-Metal Nitrides : V-Mo-N and V-W-N Alloys
Abstract : Transition-metal nitrides are known for their high hardness, good wear resistance, high-temperature stability, and chemical inertness. Because of these properties, they are extensively used in many industrial applications, notably as protective wear, erosion, and scratch resistant coatings, which are often subjected to high thermo-mechanical stresses.

3. 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

5. Theoretical understanding of stability of alloys for hard-coating applications and design
Abstract : The performance of modern hard coating materials puts high demands on properties such as hardness, thermal stability and oxidation resistance. These properties not only depend on the chemical composition, but also on the structure of the material on a nanoscale. READ MORE
