Mechanical properties of materials and associated engineered components are controlled
by the material structure at various lengths and time scales. As materials are being further …

Modern aero and stationary gas turbine engines have been designed with much higher
compressor-pressure ratios and thrust-weight ratios than earlier models, and these ratios …

This study aims to develop an abradable coating suitable for silicon carbide-based ceramic
matrix composites (SiC-CMCs) and further clarify the coating performance. BSAS-polyester …

This work develops a two-scales macro-micro approach to address the challenge in
calibrating crystal plasticity microstructural models when samples undergo necking prior to …

Gas turbine engines experience “rub” when the rotating blades come in contact with a static
abradable coating. This results in extreme strain rates and dynamics inside a high …

The main solution to the challenge of maintaining maximum sealing in the compressor
section of each gas turbine is the use of abradable coatings. These coatings have a double …

The precipitation-strengthened Nickel-based alloy Inconel® 740H®(IN740H) exhibits
increased ductility at higher applied strain rates during quasi-static tensile tests at an …

Abradable systems are used in the aeronautical industry to improve the efficiency of gas
turbine. Those materials are exposed in service to temperature up to 450° C. The increase in …

Abradable coatings enable small tip clearances within gas turbine engines to be achieved.
These coatings allow blades to cut their ideal paths during engine running-in and act as a …

In this study, a double-layered CuAl/PHB-NiAl seal coating was prepared on a GH4169
substrate by atmospheric plasma spraying. The evolution of the microstructure and …
