Finally, another limitation of this study was the use of a Ti-13Zr binary alloy
in an animal model, which differs from the Ti-15Zr characterised and used in the finite element analysis.
It is shown clearly that the cell volume V expands for either martensite or austenite with Nd addition to Ni-Ti binary alloy
from 0 at.% to 20 at.%.
Figure 1 shows the XRD patterns of Pd-Si binary alloys
. The diameter of the spherical [Pd.sub.81][Si.sub.19] sample is about 10 mm while the diameter of the [Pd.sub.80][Si.sub.20] glassy ball is around 8 mm.
In a typical Al-Zn binary alloy
microstructure rich in Al that solidifies under normal cooling rates, primary Al dendrites containing dissolved zinc are surrounded by interdendritic regions containing zinc solid solution.

Taking into consideration the whole temperature range between the melting temperature of the pure reference element (Si or Al) and the corresponding eutectic temperature of an observed binary alloy
(Al-Si or Mg-Al), the following relationship can be established between [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] and the concentration of the alloying element [X.sub.i]:

 also carried out similar investigations on Pb-Si binary alloy
; it is shown that hardness increases with decreasing the cooling rate.
Some are binary alloys
in which no lead or alloying elements are added.
Among copper alloys, many binary alloys
, such as Cu-Ag [2, 3], Cu-Zr [4, 5], Cu-Sn [6, 7], Cu-Mg [8, 9], and Cu-Cr [10-12] have been widely investigated and utilized in a variety of electrical and electronic applications, including electrical energy transmission.
Muller and Galvele  studied the role of alloying elements in pitting corrosion of Al-Zn, Al-Cu, and Al-Mg binary alloys
in 1 M NaCl.
There seems to be little basic difference between the mechanism of precipitation in simple binary alloys
and in those containing a third addition.
