Abstract Zr--Ti--based alloys were designed according to the electron concentration
($e/a$) and average atomic size rules. All the compositions satisfy the same
electron concentration $e/a$=1.5 and average atomic radius 0.1496 nm as those
of the Zr$_{60}$Al$_{20}$Ni$_{20}$ bulk metallic glasses (BMG). A new technique,
laser--induced combustion synthesis (LCS) technique,
was applied to fabricate these
alloys. The LCS products mainly consist of intermetallic phases, but in
Zr$_{55}$Ti$_{10.8}$Al$_{17.1}$Ni$_{17.1}$ and
Zr$_{50}$Ti$_{21.6}$Al$_{14.2}$Ni$_{14.2}$ the amorphous phases are found.
The hardness and tribology characters are closely related to the phase content.
In general, the more the amorphous phase, the lower the hardness and the higher
the average friction coefficient.
