Experience of Developing and Introduction in Industry New Primary and Secondary Al-Alloys with Given Properties for Shape Casting

There was created data base which includes phase diagrams, results of structure and properties investigation of thousands Al-alloys, mathematical models of composition and structure influence on mechanical and casting properties. There was developed the methodology of developing casting alloys which consists from the next steps: development of alloying principles and selection of perspective alloying systems to allow the complex of given properties by using our data base; thermodynamic calculations of phase diagrams perspective alloying systems; experimental structure investigations of perspective alloys; mathematical modeling of composition and structure influence on mechanical and casting properties; experimental investigation of all properties complex and choice the best alloys; optimization of composition and technological regimes of production best alloys for receiving needing properties, final choice the best alloy. By using that methodology there were developed tens new alloys with different complex of properties. Some of new alloys will be present in the paper.
