Description
Surface layers of icosahedral Al84Mn16 have been formed for the first time by ion-beam mixing of deposited Al/Mn layers on Al substrates at approx.80 0C and by either of two rapid electron-beam heat treatments of such layers. The well-defined temperature histories allow us to place limits on the melting point (6600C < T/sub m / < 9300C) and the time needed for nucleation of the icosahedral phase from the melt at 6600C (tau/sub n / < 900 ns). The microstructures observed place restrictions on a proposed microtwinning structural model
