<p>A joined body of a ceramic member and a metallic member is used as tappets in internal-combustion engines, tools employing brazing etc, and is joined to each other through a layer of a brazing filler material, in which the brazing filler material has a solidus point of not higher than 700 DEG C, the metallic member comprises a metallic material of which the pearite transformation is brought about at a temperature not higher than the solidus point of the brazing filler material or is inhibited, and the metallic structure after joining comprises at least one of a suercooled structure and a martensite structure. A joining process for producing the joined body comprises the steps of heating an assembly of the ceramic member, the metallic member and the brazing filler material arranged in the position to or above the austenitic transformation point of the metallic material, and cooling the assenmbly at a predetermined cooling rate by gaseous medium cooling.</p> |
