there are only three countries in the world capable of manufacturing this: the US, UK, and Japan.
>>217182181what is this?
>>217182210Probably powder metallurgy.
>>217182181explain what it is
jet engines. only a few countries can mass produce the critical components of top tier (commercially and militarily competitive) jet engines in the world. that's the hot section turbine blade.
there are some zoomers in turdgay trying to produce these geg
>>217182210metals aren't perfectly uniform, they're made out of a lot of microscopic "grains"but each of those boundaries between grains is a weak point, and the things in the OP are turbine blades, which get very hot and there's a lot of weird forces pulling and pushing on them, so metallurgists have spent decades trying to produce metals with fewer boundaries, preferably one massive, uniform, continuous crystal would be best, and as far as I know only american aerospace companies, rolls royce, and some japanese conglomerates can produce this stuff right now
>>217182406>>217182225thanks fir the explanation
>>217182210its a jet engine turbine blade, he probably watched the most recent video posted by youtube channel Veritasium in which they recorded a tour of UK's Rolls-Royce jet engine manufacturing facitility where the process of growing a single mono-crystal of Nickel-Iron alloy is shown and OP decided it affords him bragging rights on South-east Asian betelnut chewing forum.
>>217182181The m88 built for the Rafael has single crystal, so I guess add France to that list.
>>217182406though perfect cleavage would be detrimental for many applications of metal. i expect this sort of thing is for very specific applications.
