ABSTRACT:
Method for producing an elongated sintered article, characterized by the steps including filling powder material in a pipe, carrying out plastic deformation of the pipe filled with the powder material, and heating the pipe filled with the powder material to burn and/or sinter the powder material.
The method of the present invention is advantageously applicable to production of wire or rod of ceramics, particularly so called new ceramics or fine ceramics, sintered alloys or their combination, which are difficult to shape or mold by conventional process such as wire-drawing, rolling or extrusion of powder material which is difficult to mold and machine after the powder material is sintered.
