Review of Elementary Crystallographic Cells of Important Intermediate Phases in Golden Alloys
Journal Title: American journal of Engineering Research - Year 2018, Vol 7, Issue 2
Abstract
Pure gold is rarely used, mainly from its low mechanical properties, first of all the strength and hardness, but the toughness is however on a high level. For improving the strength and hardness the gold shold be alloyed with different metals, while some metalloids (as aluminium and silicon) have shown detrimental effect (dramatically reduced the toughness)Golden alloys have found a wide application in jewel making but also in other fields, as for coins, in stomatology, etc. Depending from the kind of usage, those alloys are produced but before they should be alloyed with proper metal(s). Many casting and/or mechanical properties of golden alloys are known, but their crystallographic characteristics still are not well known, even to metallurgists and specialists in production of those alloys. Further, after applying a kind of heat treatment (either the hardness is increased or not), some changes in crystallographic structure of golden alloys are subjected to change. Here will be presented the elementary cells of different crystallographic structures in most known gold binary alloys, which are important for usage.
