In order to evaluate the progress of sintering in powder steel compacts, two experiments were performed. First, the electrical resistivity of a die pressed compact was continuously measured during a sintering cycle up to 1130 °C inside an adapted dilatometer. The main changes occur at intermediate temperatures, since the resistivity falls by a factor of about 100 between room temperature and 800 °C and is almost constant afterwards. In the second set of experiments, partially sintered specimens are submitted to a tensile test until failure and their fracture surfaces are analysed in terms of welded area fraction of interparticle contacts...Read less <
