invar การใช้

• Note the related particular Fe Ni alloy Invar which exhibits minimum thermal expansion.
• The backplane assembly is made of graphite composite, invar, and titanium.
• An Invar piston can be cast and machined, just like an aluminum piston.
• The same electronic structure transition is believed to be a causal factor in Invar behaviour.
• *An Invar piston is an economical choice to avoid steam leaks and cylinder wear.
• The Invar alloy is not intrinsically expensive; only low demand makes the price high.
• Guillaume is known for his discovery of nickel-steel alloys he named invar and elinvar.
• The Invar enables the tank to hit targets at twice the range of the 125mm shells.
• Instrument screw shafts are generally made of Invar, to prevent temperature from changing tolerances too much.
• In 1896 Charles 蒬ouard Guillaume discovered the nickel based alloy "'Invar " '.
• High-precision sextants have an invar ( a special low-expansion steel ) frame and arc.
• Invar and Elinvar are able to resist magnetic fields, allowing the watch to continue to keep accurate time.
• In those used in IMAX projectors, the electrode bodies are made from solid Invar and tipped with thoriated tungsten.
• A seismograph is also sensitive to changes in temperature so many instruments are constructed from low expansion materials such as nonmagnetic invar.
• The Type 99 can fire tandem shaped charged ATGMs similar to the Russian Invar with a range of up to 5 kilometres.
• For use as the compensation balance he developed a slight variation of the invar alloy which had a negative quadratic coefficient of expansion.
• The bimetallic temperature-compensated balance wheel was made obsolete by the discovery of low-thermal-coefficient alloys invar and elinvar.
• Scale materials include chrome on glass, metal ( stainless steel, gold plated steel, Invar ), ceramics ( Zerodur ) and plastics.
• Where can I find data on the thermal conductivity of Invar over a range of temperatures, say from 300 K to the melting point?
• A solid Invar balance with a spring of Elinvar was largely unaffected by temperature, so it replaced the difficult-to-adjust bimetallic balance.
