Production of Fe-TiB2 composite using liquid phase sintering

Abstract [sv]

This thesis work focus on evaluating the metallurgical bonding between the TiB2 and iron grains in the Fe-TiB2 composite. The starting materials were commercial materials in form of Ferro-boron and Ferro-titanium that together with pure TiB2 powder formed a material with the composition seen below: FeB + FeTi + TiB2  52.3TiB2 + 45.7Fe + 2Ti During sintering an iron liquid phase is formed where the boron from the FeB diffuse to the titanium in FeTi which enables the formation of TiB2. The temperature used in the liquid phase sintering was chosen just above the three phase region, Fe-TiB2-liquid in the phase diagram, to get an adequate densification of the samples. However, the temperature could not be too high because of the internal stress and deformation the samples would have been exposed to. After sintering the material properties and microstructure were examined through Palmqvist indentations, Fargo and Transverse-Rupture-Strength tests and SEM studies including EBSD. Through these tests the hardness was measured to 1323 HV and the microstructure considered to be fine with well distributed phases. The EBSD also showed that the brittle Fe2B phase is present close to the TiB2 grains and that the porosity gives unreliable results for the Fargo and TRS-tests. The composite was impregnated with copper to show that it may be possible to achieve wetting of the TiB2 phase by casting and to perform new tests on the material with less porosity
