A bonding member that includes a resin body defining an airtight interior, and a bonding material enclosed in the interior of the resin body. The bonding material is a mixed powder that includes a plurality of particles of a first metal powder and a plurality of particles of a second metal powder. The second metal powder reacts with the first metal powder when melted to thereby produce an intermetallic compound. The resin body has a melting point higher than a softening point of the mixed powder.

A radiant heater adapted to fit on the head of a hookah. The heater uses one or more resistance ribbons to generate heat which is transferred to shisha in the hookah. The heater includes a chimney which surrounds the resistance ribbon and provides a chimney siphoning to remove heat when the heater is not in use and a heat transfer plate which includes one or more projections to vent excess heat. Air is drawn through the top of the chimney and is heated by the resistance ribbon. The heated air mixes with cool air drawn through a ventilation space below the chimney and the mixed air drawn through one or more vents in a heat plate. The heat transfer plate and hot air vaporize the shisha.

A method for producing a metal structure comprising a porous inter-dendritic matrix defining a network of dendritic channels, the method comprising the steps of: preparing an alloy melt comprising a metal element and at least one alloying element, cooling the alloy melt to a solid alloy, wherein the cooling promotes formation of a network of dendrites rich in the at least one alloying element within an inter-dendritic matrix rich in the metal, dealloying the solid alloy to remove alloying element from the dendrites and the inter-dendritic matrix to obtain the metal structure.

The present invention provides a highly fracture resistant, fatigue resistant copper-based alloy material and the like for which, for example, even when the material is subjected to repeated deformation consisting of loading of stress for applying a shape-memory alloy-specific strain and unloading of same followed return to the original shape, the alloy material is not susceptible to persistence of such strain. This copper-based alloy material has a multiphase structure in which a B2-type crystal structure precipitated phase is dispersed in a β-phase-comprising matrix.

A method of casting an article includes forming a melt comprising copper, introducing manganese into the melt to produce a copper-manganese alloy, and casting the copper-manganese alloy in a mold to form the article. The carbon and oxygen contents of the copper-manganese alloy are controlled in order to control the formation of graphite, manganese carbide, and/or manganese oxide particles within the article. Copper-manganese alloys containing carbon are also provided, as well as articles made therefrom in cast or wrought form.
