摘要： PROBLEM TO BE SOLVED: To manufacture a blank of an exterior primary part which introduces much lower cost of manufacturing than the cost encountered in traditional technology. SOLUTION: As a method of manufacturing a hollow blade for turbo machinery, a blade is made from a preform obtained from the exterior primary part. Then each of the primary parts provided with a base part is formed by planarizing the blank 42 cut away from a ring 30, which is provided with a bump 32, having a large diameter d to reduce costs.

摘要： PROBLEM TO BE SOLVED: To apply upsetting to a columnar powder metallurgical slug having high slenderness ratio without causing buckling and oxidation. SOLUTION: The upsetting method in this invention is as the followings. The slug 1 is placed at lengthwise in a sleeve whose internal wall leaves a space to the lateral surface of the slug 1 and the slug 1 and sleeve assembly is placed in an upsetting container 10 and the upsetting force is exerted on the slug 1 on at least one of this traverse surfaces until a determined slenderness ratio is obtained, and the slug 1 is separated from the sleeve. By this invention, the slug is continuously upset but only the slug is upset and this is permitted because of the space formed by the internal wall of the sleeve. For example, the sleeve material made of the steel is not welded or seized to the slag which means that it is unnecessary to be machined in order to separate the two after operation.

摘要翻译：要解决的问题：将镦锻应用于具有高细长比的柱状粉末冶金块，而不会引起翘曲和氧化。解决方案：本发明的镦锻方法如下。芯块1纵向放置在套管中，其内壁留在块1的侧表面上的空间，并且块1和套筒组件放置在镦锻容器10中，并且镦锻力施加在块1上至少一个该横向表面，直到获得确定的细长比，并且将块1与套筒分离。通过本发明，塞子连续地不舒服，但仅仅是塞子不舒服，并且这是由于由套筒的内壁形成的空间而允许的。例如，由钢制成的套筒材料没有被焊接或者被抓到炉渣，这意味着为了分离两个操作而不需要加工。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To reduce the thickness of a thermal-insulating means for hot-die type forging press.
SOLUTION: Regarding the hot-die type forging press with an operating temperature above a temperature T, this forging press comprises two dies 7, 8 between two die supporting elements 4, 5 and the thermal-insulating means 6, 6' are placed between each die 7, 8 and the respective supporting element 4, 5. In the press, the above thermal-insulating means 6, 6' comprise at least two superposed layers A, B, and a first layer A contains a first material having mechanical and thermal properties suitable for operating at a temperature exceeding the temperature T, and a second layer B contains a second material having mechanical and thermal properties suitable for operating at a temperature below the temperature T, and the thermal conductivity of the second material is lower than the thermal conductivity of the first material and also, is almost equaled to 0.2 W/(m×K) with a tolerance of 10%. Thus, the thermal insulating means having thin thickness can be effectively obtained.

摘要： The cylindrical billet (1), based e.g. on nickel and cobalt produced by powder metallurgy, is inserted in a jacket with a gap between it and the billet's lateral surface, and the assembly is placed in a ramming pot (10) so a force can be applied to it to produce a slenderness ratio of more than 2.8 : 1. The base of the jacket has a recess (5) shaped to receive the end of the billet, and its upper end is closed by a welded cover (6) with a recess (7) to hold the billet in position, with the weld being broken during the ramming process.
