Nickel-based superalloys are used in load-bearing structures requiring the highest homologous temperature of any common alloy system (Tm = 0.9, or 90% of their melting point). Among the most demanding applications for a structural material are those in the hot sections of turbine engines (e.g. turbine blade). They comprise over 50% of the ...
He used as his inspiration the old Breton flag (a centred black cross on a white background), called Kroaz Du (Black cross), and the flags of the United States and Greece as these two countries were seen at that time as the respective symbols of liberty and democracy. The nine horizontal stripes represent the traditional dioceses of Brittany ...
Most countries in Europe, the United States, and other parts of the world lagged behind in the development of HEAs. Significant research interest from other countries did not develop until after 2004 when Yeh and his team of scientists built the world's first high-entropy alloys to withstand extremely high temperatures and pressures.

Inconel 718 is commonly used for cryogenic storage tanks, downhole shafts, wellhead parts, [44] and in the aerospace industry -- where it has become a prime candidate material for constructing heat resistant turbines.
The 2024 Paris Olympic Games have showcased quite a bit of the red, white and blue colors that many of the national flags have. Skip to main content. 24/7 Help. For premium support please call: ...
For example, alloy 020 is designed to be resistant to sulfuric acid, and the DS Incoloy is to be used in heat-treating furnaces with reactive atmospheres and many heat cycles. Incoloy 020 "exhibits excellent corrosion resistance in chemical environments that contain sulfuric acid, chlorides, phosphoric acid and nitric acid."
