  • Tool for friction stir welding, method of welding with the same, and processed object obtained by the same
    Patent number: 7743961
    Abstract: It is an object of the invention to reduce mixing of an impurity from a friction stir welding tool, reduce abrasion of the tool, and prevent the tool from being easily broken even though an object to be worked formed by a metal or an alloy having a high melting point of 1350° C. or more is friction-stir-welded. The friction stir welding tool according to the invention can friction-stir-weld a metal or alloy having a high melting point of 1350° C. or more as an object to be worked. At least a portion brought into contact with the object to be worked has a composition containing iridium, containing rhenium, ruthenium, molybdenum, tungsten, niobium, tantalum, rhodium, or two or more of them, and containing zirconium, hafnium, lanthanum, cerium, samarium, gadolinium, scandium, yttrium, or two or more of them, and has a Micro Vickers Hardness of 300 Hv or more.
