Method For Manufacturing A Metal Based Component And A Single-Piece, Metal Based Component

A method for manufacturing a solid, non-hollow metal based component comprising the steps of:

• providing a plurality of metal based sheets;
• arranging said plurality of metal based sheets in a stack, wherein said stack comprises a first metal based sheet, a last metal based sheet and at least one intermediate metal based sheet;
• perimetrically sealing each sheet of the plurality of metal based sheets to at least another sheet of the plurality of metal based sheets, forming at least one cavity inside of said stack;
• removing gas from said at least one cavity;
• subjecting said stack to a hot isostatic pressing process for a predetermined time at a predetermined pressure and a predetermined temperature, thereby closing the at least one cavity so that the plurality of metal based sheets of said stack bond metallurgically to each other to form a solid, non-hollow metal based component.

A solid single-piece, non-hollow metal based component comprising a body formed by at least three metal based sheets arranged in stack wherein said metal based sheets in the stack have been perimetrically sealed to each other, wherein:

• each metal based sheet in the stack has been metallurgically bonded to at least another sheet in the stack during the process of a hot isostatic pressing to form a solid single-piece, non-hollow metal based component;
• said metal based component comprises traces of former interfaces between adjacent metal based sheets;
• and
• said traces are formed by crystallographic mismatch.
