The part of the phrase "alloies" is not correct in written English.
It appears to be a misspelling or incorrect form of a word, possibly intended to be "alloys."
Example: "The jeweler explained the different types of alloys used in making jewelry."
Alternatives: "compositions" or "mixtures."
"What do you drive back home, a hatchback?" Actually, it was a hatchback: a souped-up Seat Ibiza complete with spoiler, alloys and boy-racer bucket seats.
In 1913 he had the job of making better steel alloys for gun barrels.
The first climbers used uncomfortable hammocks but portaledges – folding alloy frames with nylon floors that are clipped to the wall – allow a flysheet to be pitched against bad weather and a comfortable platform for sleeping and hanging out.
He was working in one of Sheffield's metallurgy labs and trying different alloying elements to improve the hardness of steel.
In the unlikely event that a modern-day footballer would ride a bike to work, you'd imagine it would have its own stereo system, jacuzzi and alloy spokey dokeys.
In other words, if domestic mining of the five gateway metals were curtailed for economic or environmental reasons, the knock-on effect would disrupt the supply of strategic materials needed for clean energy, super-alloys, catalysts, semiconductors, health-care products and flat-panel displays.
A shortage of these could stifle the development of better catalysts for biofuels, lightweight alloys for cars and planes, and synthetic membranes that replicate photosynthesis.This diversity of demand inevitably means some materials have to come from abroad.
With stronger, lighter fan blades, made from Hyfil instead of aluminium alloy or titanium, in a fan-jet's first compressor stage, Rolls-Royce's latest aircraft engine at the time, the RB211, would have had a significant weight-saving advantage and thus better fuel economy over rivals from General Electric and Pratt & Whitney.
The pellets of nuclear fuel are encased in hard alloys based on zirconium (which lets neutrons pass freely through), to make fuel rods.
He and his colleagues have discovered that the conditions change if a photovoltaic cell is placed a few hundred nanometres (billionths of a metre) from a hot surface made of silicon carbide alloy.
Complicating matters further, the burning fuel cannot be allowed to get too volatile for fear of cracking the microscopic engine's casing, which is made of silicon instead of high-temperature alloy.Earlier this year, Dr Epstein demonstrated that a prototype of his microscale jet engine could achieve rotor speeds of 1.3m revolutions per minute enough, in theory, to generate 17 watts of power.
