Metallic powder can be compressed into a solid metallic bar

Do you know, metallic powder can be compressed into a solid metallic bar or shape using a very powerful compression machine? Under high compression level metallic powder I pressed into each other create a solid structure which can then be placed into a very hot environment of around 1000°C to further howling the metallic structure without the heat treatment. Metallic structure is very fragile. It can be broken down very easily by by a small force.
