Patent ID: 8512630

Claim:
A composite metallic material comprising: a first metallic alloy (a1), having a body-centred cubic crystal structure, comprising titanium, vanadium, and another metal M selected from the group consisting of chromium, manganese, and any mixtures thereof; and a second metallic alloy (a2), comprising: from 38 to 42 mole % of a first metal M 1 selected from the group consisting of zirconium, niobium, molybdenum, hafnium, tantalum, tungsten, and any mixtures thereof; and from 56 to 60 mole % of a second metal M 2 , selected from the group consisting of nickel, copper, and any mixtures thereof; and with a ratio by mass (a2)/(a1+a2) ranging from 0.1% to 20% by mass, said composite metallic material comprising: a majority phase comprising titanium, vanadium and chromium and/or manganese, dispersed as grains, said majority phase having a body-centred cubic crystal structure; and at least one intergranular phase comprising at least one first metal selected from the group consisting of zirconium, niobium, molybdenum, hafnium, tantalum, tungsten, and any mixtures thereof; and at least one second metal selected from the group consisting of nickel and copper.
