Mechanical milling or mixing, as a method of introducing the reinforcement particles, assures better distribution of the particles in the consolidated material (Lee et al, 1995). This process consists of repeated welding–fracturing–welding of a mixture of powder particles in a high-energy ball mill (Suryanarayana, 2001). The central event is that the powder particles are trapped
