Alloy characterized

Owing to their numerous actual and potential applications, several ternary and complex systems of these metals, especially of aluminium, have been investigated a few examples of the systematics of Al-Me-X alloys are presented in 5.18 and in Fig. 5.41. Recent contributions to this subject have been given with the study of the systems R-Al-Cu (Riani et al. 2005, and references there in). These rare earth alloys, characterized by the formation of several intermediate phases, are interesting also as raw materials for the preparation of amorphous alloys. Regularities in the trends of their properties have been underlined. The experimental and calculated data relevant to the binary systems Al-Fe, Al-Ni and Fe-Ni have been examined and discussed in a paper concerning the assessment of the ternary Al-Fe-Ni system (Eleno et al. 2006).

The term invar alloys is used for some groups of alloys characterized by having temperature-invariant properties, either temperature-independent volume (invar) or temperature-independent elastic properties (elinvar) in a limited temperature range. A comprehensive survey of the physics and applications of invar alloys is given in [3.17].

The effect of electrolyte on surface roughness, H, was studied by Y. Sugie (1978) for five different iron alloys (characterized in Table 9.3) and is shown in Fig. 9.3. The roughness depends on electrolyte and alloy. 

Beta foiging techniques are, however, used to develop microstructures in a, a + P, and near P-alloys characterized by Widmanstatten or acicular primary a morphology in a transformed P matrix. This foiging process is typically used to enhance fi actiue-related properties, such as firacture tou mess and fatigue crack propagation resistance, and to enhance the creep resistance of a and a-P alloys. In fact, some a alloys (such as Ti-1100) are designed to be P foiged to develop the desired final mechanical properties.

Lead alloys characterized by the addition of selenium exhibit a fine grain structure even at very low antimony contents (<2%). This structure yields acceptable quality of the castings as indicated by mechanical strength, natural hardness, age-hardening and total hardness, and also yields acceptable castability characteristics. The hardness necessary for handling the battery plates is achieved by age-hardening due to finely dispersed antimony.
