Structure and properties of aluminum bronze-lead composite material

The effect of sintering regime on the structure and properties of aluminum bronze-lead composite material is studied by experiment. It is established that in order to prepare material with a uniform lead distribution and high mechanical properties the sintering duration should not exceed 5 min. More prolonged heat treatment leads to redistribution of lead with formation of a coarse-grained structure and and a drop in the material mechanical properties.
