A New, Super Heat Resistant Alloy That Has Improved Fuel Efficiency in Airplanes!

This video "World-Record Super Heat-Resistant Alloy That Has Improved the Fuel Efficiency of Aircrafts!" (ジェット機の燃費向上を実現した世界記録の超耐熱合金), created by "nimspr," introduces the amazing processing technology of a Japanese research institution.

Burning at higher temperatures reduces fuel consumption. To combat this, aircrafts, jets, and automobile makers are required to develop special material.
NIMS, introduced in the video, has developed a super heat resistant alloy that can resist extremely high temperatures and currently holds the world record for super heat-resistant alloys.

How Is the Superalloy Used?

NIMS’ superalloy is used in the latest Boeing 787, shown at 0:21 in the video.

As you can see from 0:45 in the video, ordinary metals are poly-crystalline when made in a mold, but the superalloy shown in the video is mono-crystalline with no grains, making it resistant to heat.
This super heat-resistant alloy is used in turbine blades- the hottest part on all aircraft parts.

By using the superalloy, it's possible to save 100 million yen per year, per aircraft.
The heat resistant titanium alloy by NIMS is also highly resistant to rust.
On top of that, it is incredibly light, making it a highly valued material.

In addition to titanium, which is shown in the video, there are other kinds of materials, such as iron, cobalt, nickel, aluminum, tantalum, chromium, molybdenum and tungsten.
Research institutions across japan have spent a long time researching how to combine these materials to create the perfect metal.

The experimental data collected by NIMS over several decades was used to create superalloys.

NIMS Materials Strength Standard and Technology Group conducts research on high fatigue tests which check creep properties and fatigue characteristics for superalloys.

They also focus on the recycling of materials, the design of end mills for cutting superalloys, as well as promoting low-cost, high-performance development through the establishment of material design methods. This can be seen at 1:53 in the video.
It'll be exciting to see what Japan's research institutes will come up with in the future!
