A production method of an extrusion billet includes a step of preparing a plate or lump starting material comprising a magnesium alloy, a step of performing a plastic deformation process at a rolling reduction of 70% or more to the starting material at a temperature of 250&#xb0; C. or lower to introduce a strain without generating dynamic recrystallization, a step of producing powder by granulating the material after the plastic deformation process, and a step of producing a powder billet by compressing the powder.

Production method of extrusion billet and production method of magnesium alloy material

A method and apparatus for producing a hydrogen adsorption alloy, the apparatus comprising a high speed ball mill in the form of a planetary ball mill mounted to a rotatable main shaft, wherein the planetary ball mill includes a plurality of mill pots each mounted for rotation on its own axis, a planetary gear disposed on the periphery of each mill pot, a fixed sun gear meshing with the planetary gears, and an atmosphere adjusting device connected to each mill pot. A drive rotates the main shaft causing each mill pot to revolve around the main shaft which results in the planetary gears traveling around the sun gear to rotate each mill pot on its own axis, the rotation of each mill pot being in the same direction as the rotation of the main shaft.

Apparatus for producing hydrogen adsorption alloy

There is provide an improved pulverulent body processing apparatus that is substantially free from abrasion and cleavage of the pulverizing medium to allow prolonged continuous operation and also free from small pieces of the slit member and the pulverizing medium that can be produced as a result of such abrasion and cleavage and mixed with the material being pulverized and hence can efficiently operate to produce an evenly pulverized product. Such a pulverulent body processing apparatus comprises a vertically arranged cylindrical housing, a slit member having one or more than one slits sized to prevent unit members of a pulverizing medium from passing therethrough and arranged at the bottom of the cylindrical housing, a rotary shaft arranged along the axis of the cylindrical housing and a plurality of bladed stirring members arranged vertically and secured to the rotary shaft and is characterized in that said slit or each of said slits is arranged in a flat disc and has a radial width sized to prevent unit members of the pulverizing medium from passing therethrough and a peripheral width greater than the radial width.

This present invention intends to provide a continuous type vertical planetary ball mill performing with high efficiency. In this ball mill, a mill pot is provided with an entrance and an exit which are vertically open. The entrance communicates with a charging port of a charging case which rotates together with a revolving rotary body, and the exit communicates with a discharging case fixed to a bed so as to allow only fine particles to pass through. Compressed air is supplied to bearings interposed between an airtight chamber and a fixed shaft, between the airtight chamber and a rotary shaft, and between the airtight chamber and a mill casing. As a result, this continuous type vertical planetary ball mill is stable in construction as compared with the conventional vertical type of ball mill and enables a high speed operation. Crushing performance and material quality reforming performance are improved. As a wide range of choice in production means is assured as compared with the knwon batch system, this ball mill contributes to development and production of new functional materials.
