  • Publication number: 20100116378
    Abstract: A heat-resistant magnesium alloy according to the present invention includes Mg, a major component; a first alloying element “M1” being any one or more members that are selected from the group consisting of Al and Ni; a second alloying element “M2” being any one or more members that are selected from the group consisting of Mn, Ba, Cr and Fe; and Ca; and it has a metallic structure including: Mg crystalline grains; plate-shaped precipitated substances being precipitated within grains of the Mg crystalline grains; and grain-boundary crystallized substances being crystallized at grain boundaries between the Mg crystalline grains to form networks that are continuous microscopically. Since the plate-shaped precipitated substances exist within the Mg crystalline grains, the movements of dislocation within the Mg crystalline grains are prevented, and accordingly it becomes less likely to deform.

  • Patent number: 7097914
    Abstract: A plate-shaped composite material has a first member and a second member. The first member is an expanded metal formed of a metal plate. The coefficient of linear expansion of the metal plate is less than or equal to 8×10?6/degrees Celsius. The first member suppresses thermal expansion of the composite material. The coefficient of thermal conductivity of the second member is greater than or equal to 200 W/(m×K). The second member maintains the coefficient of thermal conductivity of the composite material. This structure provides a reliable coefficient of thermal conductivity and high strength. The structure is suitable for a cooling substrate on which electronic elements such as semiconductors are mounted.

  • Publication number: 20050153156
    Abstract: A pressure casing includes a composited cast member. The composited cast member includes an iron-based porous substance whose major component is Fe and which has a large number of pores, and a cast-wrapping member whose major component is a light metal and which cast-wraps a part of the iron-based porous substance at least. The iron-based porous substance includes a connector disposed adjacent to a boundary between the iron-based porous substance and the cast-wrapping member and exhibiting a larger porosity, and a high-strength reinforcer disposed in the iron-based porous substance free from the connector and exhibiting a smaller porosity. The connector is impregnated with the cast-wrapping member, and solidifies therewith, thereby firmly bonding the iron-based porous substance and the cast-wrapping member in the composited cast member. The pressure casing secures strength with the reinforcer, and secures adhesiveness with the connector.
