Sidorov V.V., Rigin V.Y., Kablov D.Y. Organization of Cast Barstock Production from Modern Highly Heat-Resistant Cast Nickel Alloys
There have been developed super heat-resistant alloys for promising gas-turbine engines (GTE) of the 5th and 6th generation,and technologies of making such alloys. Techniques are indicated that allow, during melting, to considerably reduce harmful impurities contents, narrow the alloying intervals, considerably increase the yield, and, in terms of quality, reach the world standard levels. On the basis of the investigations conducted, there has been developed a technology of recycling 100% of foundry waste of engine producing plants and GTE blades after operation on engines. It is shown that the waste recycling by the developed technology makes it possible to produce cast barstock from heat-resistant alloys that by its quality is not inferior to metal made of new charge materials.

Petzschmann U., Wolf G., Stets W. Evaluation of the influence of different carbide forming elements on the microstructure and the properties of the ferritic ductile iron The paper presents the results of a research project. The subject of the activities wasto investigate and evaluate the cumulative effects of carbide stabilising elements on the microstructure and the properties of thick-walled castings in ferritic cast irons like EN-GJS-400-15. The project was inspired by the increasing occurrence of tramp and trace elements in the cast iron materials by the use of steel scrap and its influence on the microstructure and the properties of ferritic cast irons. The objective of the project was the development of quantitative rules to predict the level of carbide in the microstructure and its consequences for the mechanical properties.
