Evidence for self-sustained MoSi 2 formation during room-temperature high-energy ball milling of elemental powders

Abstract

We present evidence indicating that rapid, self-sustained, high-temperature reactions play an important role in the formation of tetragonal MoSi2 during room-temperature high-energy ball milling of elemental powders. Such reactions appear to be ignited by mechanical impact in an intimate, fine-grained, Mo-Si physical mixture formed after an initial milling… (More)
