, a prismatic body 12 inserted in a radial arrangement within the main body 11, and upper and lower lids 13, 14, etc. provided in the form of lids at both ends of the cylindrical length of the main body 11. .
カプセル本体１１は鋼管等からなり、本実施例

１１の外周部に、角柱体１２が放射状配置で内挿
されることによつて、超合金粉末の収容空間１５
がローター８の外周形状を設定するようにされて
いる。 The capsule body 11 is made of a steel pipe or the like, and in this embodiment has a cylinder length that allows for four rotors.The prismatic bodies 12 are inserted in a radial arrangement on the outer circumference of the body 11, so that the superalloy Powder storage space 15
is used to set the outer peripheral shape of the rotor 8.
なお、角柱体１２はHIP処理するときの圧力と
熱の伝達媒体であることから、HIP温度までは溶
融したり、極端に変形したりせず、しかも、粉末
合金と有害な反応を起さず、熱伝導率が高く安価
なものであることが望ましい。 In addition, since the prismatic body 12 is a pressure and heat transfer medium during HIP processing, it will not melt or be extremely deformed up to the HIP temperature, and will not cause harmful reactions with the powder alloy. It is desirable that the material has high thermal conductivity and is inexpensive.

ンホールがないものであればよい。 Therefore, for example, a product machined from rolled steel is optimal. However, it may be a forged material of mild steel or stainless steel. In any case, any material may be used as long as it does not contain a large amount of C, has low deformation resistance, and has no cracks or pinholes on its surface.
また、実施例では、角柱体１２は横断面が台形

ているとともに環状部は角柱体１２の柱長両端の
取付け部として機能している。 Here, the wall thickness of the bulging parts 20, 21 is made thin, and the outer peripheral edge of the bulging parts 20, 21 is an annular part with a thick wall, thereby preventing deformation of the annular part. In addition to restraining and giving priority to the deformation of the bulging portions 20 and 21, the annular portion functions as a mounting portion for both ends of the column length of the prismatic body 12.
第３図は本考案の比較例であり、カプセル本体
１１が上本体１１Ａと下本体１１Ｂとからなり、
両者を溶接１１Ｃして構成したものであり、本体

圧を受けてもほとんど変形しない。一方、円筒中
心部の粉末は上下蓋１３，１４より直接圧力を受
け圧縮変形し、もし、蓋１３，１４が平面であれ
ば欠肉の原因となる。 Here, the bulges 20 and 21 were formed during the HIP process, since the prismatic body 12 is solid and hardly deforms even when subjected to external pressure. On the other hand, the powder at the center of the cylinder is compressed and deformed by direct pressure from the upper and lower lids 13 and 14, and if the lids 13 and 14 are flat, this will cause underfilling.
そこで、変形量を見込んで薄肉でかつ略円錐形

この際、角柱体１２も僅かに変形するが軸方向
には略一様で予測可能である。 At this time, the prismatic body 12 also deforms slightly, but it is approximately uniform and predictable in the axial direction.
HIP処理後に、熱処理、超音波探傷を行つた後
に、軸方向に直角に本例では５個所を切断２２す
