Abstract
For the purpose of obtaining sintered products of complicated shapes or of a shape which is lengthening in compression direction, joining of short compacts of a simple shape is studied, and in particular the feasibility of infiltration method is investigated. Torsional strength of the joined compacts are examined, and compared with that of the conventional compacts.
The results obtained are as follows:
(1) Both joining of the pre-formed compacts and strengthening of the base metal can be carried out in one process.
(2) The torsional strength of the compacts joined by the infiltration method can compete with that of compacts infiltrated by usual way. This result does not depend on whether the preforms are made of green compacts or sintered ones.
