This report describes the results of our experiments on Fe-Cu-B based materials with regard to the dimensional change both during and after sintering, and the analysis of each phase of sintered compacts.
With the addition of no less than 0.03% of boron, Fe-Cu based materials show a shrinkage after sintering, and the maximum shrinkage with the addition of about 0.15% of boron. The dimension of sintered compacts contracts with an increase in copper content and rising in sintering temperature.
This is because the boron addition prevents the diffusion of copper into iron lattice and causes the occurrence of a liquid phase of Cu-B during sintering.
