Sintering is a physical-metallurgy process, during which powder particles coalesce to form a connected solid mass without the melting of the particles. The phase field model (PFM) is an ideal technique for simulating materials science problems involving moving boundaries and has been applied to study the sintering phenomena. However, in typical PFM sintering simulations, each powder particle requires one order parameter, which leads to high computer memories to store multiple order parameter fields. We developed a method to dramatically reduce the memory demands, in which particles not in direct contact are assigned to the same order parameter. Furthermore, an additional label is assigned to the region occupied by each individual particle. Thus, the motion of each particle can still be explicitly tracked. This innovative method is implemented to simulate 3D nickel particle sintering during metal brazing processes.
