The aim of this book is to acquaint the reader with what the authors regard as the most basic
characteristics of quasicrystals--structure, formation and stability, and properties--in …

In order to investigate friction and fretting on quasicrystals at room temperature in a reliable
manner, we have subjected sintered samples to tests in a vacuum chamber evacuated to a …

This study presents research works about the effects of heat treatment on recrystallized
equiaxed grain size, precipitation, room temperature (RT) toughness and ductile to brittle …

We review scanning tunnelling microscopy (STM) studies of the surfaces of periodic Tsai‐
type approximants. Although they are useful analogues to the Tsai‐type quasicrystals, the …

Quasi-periodic materials hold unique properties, but mass-producing bulk materials with
such structures remains challenging. The rational approximant phase belongs to the Bravais …

We have studied the optical conductivity of several intermetallic compounds of the Al-Cr-Fe
system in a broad range of frequencies. Depending on composition, the crystallographic …

Based on transmission and scanning electron microscopy, x-ray diffraction, electron
microprobe and differential thermal analyses, the solidus surface of the ternary Al–Cr–Fe …

Phase equilibria in the Al-rich region of the Al–Mn–Ni alloy system were studied at 1000,
950, 850, 750, 700, 645 and 620° C. Three ternary thermodynamically stable intermetallics …

Two new orthorhombic approximants of the decagonal phase as well as a γ-brass type
phase are pointed out in the Al–Cr–Fe system. Analysis of diffraction data shows that they …

Ternary phases in the Al-rich region of the Al–Mn–Ni alloy system were studied at 950, 850
and 750° C. Two new ternary intermetallic compounds were revealed: the φ-phase (Al5Co2 …
