The present invention addresses the problem of providing a joining method that enables metal members to be joined together in a preferred manner. The present invention is characterized by comprising a friction stirring step for joining a first metal member (1), a second metal member (2), and an auxiliary member (10) together by inserting, in an inner corner section, a tip end-side pin (F3) that is rotatable, and causing a rotation tool (F) to relatively move along the inner corner section in the state where the outer circumferential surface of a base end-side pin (F2) is pressed against the auxiliary member (10) while the tip end-side pin (F3) is brought into contact with the first metal member (1), the second metal member (2), and the auxiliary member (10).

The present invention is characterized by including a bonding step in which: a rotating rotary tool (F) is inserted from only a surface (10a) side of an auxiliary member (10); and in a state where only a stirring pin (F2) is brought into contact with the auxiliary member (10), the base end side of the stirring pin (F2) is left exposed, and the outer peripheral surface of the stirring pin (F2) is brought into slight contact with a first metal member (1) and a second metal member (2), the rotary tool (F) is moved relatively along butted parts (J1, J2) to bond the first metal member (1) and the second metal member (2) together via the auxiliary member (10). The present invention is also characterized in that: the auxiliary member (10) comprises, on at least one side surface thereof, an inclined surface that tapers going away from the surface (10a); and the first metal member (1) and/or the second metal member (2) comprises an inclined surface (end surface 1a, 2a) which inclines from the front surface to the rear surface in accordance with the inclined surface of the auxiliary member (10).

ALUMINUM ALLOY AND ALUMINUM ALLOY DIE CASTING MATERIAL
Provided is a non-heat-treated aluminum alloy which has excellent casting properties and is high in both strength and toughness. Also provided is an aluminum alloy die casting material which is high in both strength and toughness, and which, in addition to having minimal difference in characteristics between regions thereof, is not prone to be affected by aging. The present invention provides an aluminum alloy characterized by containing 5.0-12.0 mass% Si, 0.3-1.9 mass% Mn, 0.01-1.0 mass% Cr, and 0.001-0.05 mass% Ca, the remainder comprising Al and unavoidable impurities, the content of Mg in the unavoidable impurities being less than 0.3 mass%.
A method of manufacturing a liquid-cooled jacket, configured by a jacket body (2) having a bottom part and a peripheral wall portion (11) rising from a peripheral edge of the bottom part and a sealing body (3) that seals an opening part of the jacket body (2) and obtained by joining the jacket body (2) and the sealing body (3) through friction stirring, is characterized in that in the present joining step, after a rotating tip side pin (F3) is inserted into a start position (SP1) set on the surface (3a) side of the sealing body (3) further from a set movement route (L1), the tip side pin (F3) is gradually inserted until reaching a predetermined depth while a rotation center axis (Z) of a rotary tool (F) moves to a position overlapping the set movement route (L1).
