Influence of La Addition on the Properties of Pre-alloyed Fe-based Matrix Material
Abstract:Under some fixed sintering temperatures,the effects on the sintering properties and microstructures of Re(La) content in Fe-based matrix were studied. The optimum mechanical properties of Fe-based matrix were attained at the La content of 0.1%. The distribution of matrix and the retention of diamond in matrix were also improved with proper La addition.
