Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
An alloy capable of withstanding high temperatures, high stresses, and often highly oxidizing atmospheres.
- ‘The majority of the nickel-base superalloys utilize the combined strengthening of a solution-hardened austenite matrix with’ precipitation.’
- ‘Investment cast structural components are produced in a wide range of air-melted steels, cobalt alloys and vacuum cast nickel-based superalloys.’
- ‘While others in the market readily acknowledged that demand from the stainless steel sector is slack, order books for nickel-bearing engineering steel and superalloys are strong, they said.’
- ‘About 65% of the cobalt used in the United States is used to make alloys, primarily superalloys.’
- ‘Cr compounds are used industrially as catalysts, corrosion inhibitors and as an alloying metal in making stainless steel and various superalloys.’
- ‘About three-quarters of all rhenium consumed in the United States is used in the manufacture of superalloys - alloys containing iron, cobalt, or nickel.’
- ‘The effect on microstructure is not nearly so clear in other cases where a well defined substructure is produced, e.g. Al-Mg alloys, ferritic Fe-Si, Fe-Cr and Fe-Ni alloys, austenitic stainless steels, and nickel superalloys.’
- ‘The backlash could be harsh if that happens, some warned, because, despite the market's current weakness, underlying demand - particularly in the superalloys sector - is firm.’
- ‘The barrier coating can be disposed between a metal substrate (e.g., a superalloy) and an oxidation-resistant coating, preventing the substantial diffusion of various elements at elevated service temperatures.’
- ‘Another 20 to 25% is used as alloy additions in nickel-base superalloys and heat-resisting steels.’
- ‘Advanced materials (ceramics, superalloys, etc.) provide greater strength and temperature resistance.’
- ‘Nickel is also used to make superalloys, alloys made primarily of iron, cobalt, or nickel.’
- ‘Look at detector materials - the first medical X-ray tube - or superalloys or advanced ceramics or thermal barrier coatings that make it possible to run aircraft engines and power systems at higher temperatures and higher efficiencies.’
- ‘A distinction is usually made between those alloys that are primarily used for high-temperature strength, commonly referred to as superalloys, and those that are primarily used for corrosion resistance.’
- ‘It uses neural network modelling to predict the impact very expensive additives such as rhenium and platinum might have on the heat resistance of superalloys.’
