<P>PROBLEM TO BE SOLVED: To provide a shock pressurization/heat treatment method of porous material and an apparatus therefor which makes it possible to apply the shock of a longer shock time than that in the conventional technique or a plurality of times to a body to be treated, enhances the transformation rate in phase transformation treatment, permits the manufacture of a defect-free sintered body in sintering treatment and, at the same time, makes the recovery of porous treated material secure and easy. <P>SOLUTION: In the treating method, porous material is put in a metallic sealed vessel, an explosive located on the outer periphery of the vessel is exploded, a shock pressure generated thereupon is applied on the porous material and the porous material is shock-pressurized. Therein, a subject of metallic hollow shape is located on a center of the porous material beforehand, the porous material and the subject are allowed to contract by the shock pressure, thereupon, the inner wall surface of the subject is allowed to collide with the opposed wall surface or another metallic subject located in the subject, thereby, a shock wave is generated and, in addition to the shock pressure due to the explosion of the explosive, the shock wave is applied to the porous subject. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
