Title:
ENGINE PARTS FOR AIRCRAFT
Document Type and Number:
Japanese Patent JP2784162
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To produce lightweight engine parts for aircraft whose strength is increased and having high temp. heat resistance and oxidation resistance by subjecting the one obtd. by interposing SiC fiber layers between Ti-Al base alloy foils, furthermore arraying the fibers in a specified direction and laminating the same to HIP working and diffusedly joining the same.
SOLUTION: Annular SiC fiber layers 2 in which SiC fibers 1 having about 140μm fiber diameter are finely arrayed in the circumferential direction and SiC fiber layers 2' finely arrayed in the radiate direction are laminated in such a manner that they are interposed between Ti-Al-Cr alloy sheets 4. This laminate is sealed into a can, which is applied with loads, and HIP diffused joining is executed. This is subjected to finish working to obtain engine parts for aircraft. This parts are subjected to fine crystallizing treatment to form into a Sic fiber reinforced composite material using Ti-Al-Cr alloys as a matrix and having about 2% indoor ductility as the forged material, by which it is excellent in high temp. heat resistance and oxidation resistance. The content Vf of the fibers is regulated to about 25 to 30% and the density to about 3.6g/m3, and it is remarkably lightweight.
