“…27,28 However, the formation of the body-centered cubic ␥-phase (Al 4 Cu 9 -type) or of the Fe 3 formation cannot be observed with the present time resolution. Another important difference with conventional heating is the spectacular enhancement of the phasetransformation rate upon microwave irradiation.…”

The effect of rapid microwave heating has so far been evaluated mainly by comparing the state of materials before and after microwave exposure. Yet, further progress critically depends on the ability to follow the evolution of materials during ultrafast heating in real time. We describe the first in situ time-resolved monitoring of solid-state phase transitions during microwave heating of metallic powders using wide-angle synchrotron radiation diffraction. Single-phase Al-Cu-Fe quasicrystal powders were obtained by microwave heating of nanocrystalline alloy precursors at 650°C in <20 s.

“…In our recent papers we report that the combination of MA and subsequent heating of Al-Cu-Fe powder mixtures results in the formation of a single-phase icosahedral QC structure [35][36][37][38][39]. The aim of this paper is to compare the effect of various routes of MA on the QC phase formation in the Al-Cu-Fe system.…”

“…The synthesis of single-phase Al-Cu-Fe QC's by conventional casting is nevertheless difficult, due to their very narrow composition domain [6]. Recent research efforts were devoted to the mechanosynthesis of quasicrystalline Al-Cu-Fe powders by powder metallurgy (P/M) routes [7][8][9][10] and their pressure-or field-assisted consolidation [11]. The influence of external pressure onto the sequence of solid-state interdiffusion reactions leading to single-phase Al-Cu-Fe QC's was evaluated in a recent paper [12].…”
