摘要: High-energy mechanical alloying was utilized to study the alloy formation between Al and Mn. A modified SPEX mill designed investigate role of milling energy power on enhancing solubility Mn in Al. Despite having a large influence kinetics (an increased rate 3.25×) no further grain refinement or degree observed with increasing energy. It is hypothesized that this particular binary system takes place controlled by interfacial surface area created particles matrix. However, extensive comminution eventually likely leads an autocatalytic exothermic reaction matrix, leading equilibrium phase Al6Mn. This reduces and, turn, frustrates alloying, highlighting practical limits creating solid solutions through alloying.
