"' Solid solution strengthening "'is a type of alloying that can be used to improve the precipitation of intermetallic compounds ).
32.
They can be further classified as homogeneous ( consisting of a single phase ), or heterogeneous ( consisting of two or more phases ) or intermetallic.
33.
Some intermetallic materials e . g . do exhibit metal clusters, reminiscent of molecules and these compounds are more a topic of chemistry than of metallurgy.
34.
Two processes play a role in a solder joint formation : interaction between the substrate and molten solder, and solid-state growth of intermetallic compounds.
35.
This leads to formation of layers of several intermetallic compounds with different compositions, from gold-rich to aluminium-rich, with different growth rates.
36.
All-aluminum systems in semiconductor fabrication eliminate the " purple plague " ( brittle gold-aluminum intermetallic compound ) sometimes associated with pure gold bonding wire.
37.
The process of the growth of the intermetallic layers causes reduction in volume, and hence creates cavities in the metal near the interface between gold and aluminium.
38.
The process of the atomic vibrations is important for materials of different classes : for metallic, covalent, ionic crystals, semiconductors, intermetallic compounds, interstitial phases.
39.
These interactions include formation of Cu-In-Ga intermetallic alloys, formation of intermediate metal-selenide binary compounds and phase separation of various stoichiometric CIGS compounds.
40.
Metallurgy is a domain of materials science that studies the physical and chemical behavior of metallic elements, their intermetallic compounds, and their mixtures, which are called alloys.
