The present invention provides a magnesium-based composite material that can achieve excellent performance such as high tensile strength not only at ordinary temperature but also at high temperature. The magnesium-based composite material of the present invention is AlCa-containing magnesium-based composite material, wherein said composite material is obtained by a solid-phase reaction of an aluminum-containing magnesium alloy and an additive, said additive being calcium oxide, and said composite material contains AlCa formed in the solid-phase reaction. In the magnesium-based composite material, CaO, in combination with AlCa, can be dispersed.

A metallic glass laminate of the present invention is characterized in that a metallic glass layer of amorphous phase is formed on the substrate surface, and there is no continuous pore (pinhole) through the metallic glass layer. The metallic glass laminate is preferably obtained by solidification and lamination of at least part of the metallic glass powder in the molten state or in the supercooled liquid state on the substrate surface. Because of the dense metallic glass layer of homogenous amorphous phase, the functionalities of metallic glass such as corrosion resistance and wear resistance can be satisfactorily provided. A thick and a large-area metallic glass layer can be formed. The metallic glass layer can also be formed into various shapes within the supercooled liquid temperature range. In addition, a metallic glass bulk can be obtained by removing the substrate. The metallic glass laminate and the metallic glass bulk are utilized for a fuel cell separator, a hydrogen separation membrane, a hydrogen sensor, a solder-corrosion resisting member, etc.

Metallic glass laminates, production methods and applications thereof

A seal for an endless track has a cross section having a centerline parallel to an axis of the seal and a configuration symmetric with respect to the centerline of the cross section. The seal can include an elastically deformably configured portion having a cross section like alphabetical letter X, and a protrusion extending from an intersection of legs of letter X in a bushing-side direction further than a plane connecting bushing-side end portions of the legs of letter X. The protrusion has an end surface where the protrusion contacts the bushing. The seal can further include an embedding portion embedded in a space between legs of letter X, on a bushing-side of the intersection of the legs of letter X.

An endless track includes an iron link belt, a continuous pad, and a connecting device. The iron link belt includes a link unit assembly constructed of a plurality of link units connected to each other. Each link unit includes a pair of links. The iron link belt may include a plate welded to the pair of links and extending perpendicularly to a direction in which the link unit assembly extends. The continuous pad includes the same number of core metal plates as that of the link units and a single urethane rubber belt covering and being attached to a ground opposing surface of each of the core metal plates. The urethane rubber belt extends continuously over all of the core metal plates. The urethane rubber belt may include a small thickness portion positioned between two adjacent core metal plates. The connecting device connects the iron link belt and the continuous pad.
