Thanks for the post
According to wikipedia:
Titanium Sponge Plant is an Indian manufacturing plant that produces titanium sponge, a material widely used in aeronautics, light defence vehicles, and other applications. It is located at Kerala Minerals and Metals Ltd (KMML), Chavara, Kollam district of Kerala. Notably, It is the only plant in the world in India has the third-largest reserves of Titanium containing minerals, and was the sixth-largest country by Titanium production in 2013.
Using the indigenously made titanium sponge, VSSC realized the aerospace-grade alloy, having formula Ti6Al4V, at Mishra Dhatu Nigam (Midhani) in Hyderabad.
Some alloys developed by DMRL for aerospace projects:

Good effort is made. Needs to be congratulated for the data. These are very old articles, spanning back to 2012/2014 and earlier. There must have been quite a good development by now, can anyone throw light on the latest development vis a vis what is still we are lacking in producing composite materials required for the Kaveri Engine.
what composite you are talking about?
no military turbofan in the current age uses composite in even cold parts.
its very distant dream.
even 5th gen engine like f135 uses single crystal blades and metal bypass duct.
Are these single crystal blades coated with EBPVD? What colour is the uncoated surface.
Great thread on cmc materials and its use in engine technology
HAL has made their own aerospace grade metal 3D printer:
You mean 3D printing? Because that EOS M400 is from EOS Gmbh, A German Company.
There seems to be a small scale 3D printer from Wipro for Aerospace Products. Don't know what happened to that. Another thing is we need to seriously look into Indigenous Jet Engine Making machines, some of them like EBPVD lab scale machines are already used for Shakti engines. We need 100s of Engines everyyear, and I doubt we could comfortably import as much as possible. Yours truly Unkill Sam has some tricks to play here. The Germans aren't our best friends. Don't know about Japanese.
No one is friend as far as strategic capabilities concern. You need home based test facilities and indigenous programme. As you reach on sufficient maturity you will get offer for Co-development.
Is it the latest development that is being used by GE and others? This 4th generation SC blade is in 2021.
