Material-technological conversion of nickel alloys. Part 1. The classification and application of nickel alloys

The present study was created as a result of the execution of the project entitled "Technological conversion of nickel alloys working under extreme conditions". This project, contract No.: TANGO2/340100/NCBR/2017 of 28.04.2017 is realised by the Foundry Research Institute in Kraków under TANGO2 Programme. It was created on the basis of the International Non Co-financed Project No. 721/NNICKEL/2010/0 entitled "Defining the impact of the technological process on the quality of castings of nickel superalloys for the needs of the energy, chemical and automotive industries".
In the first part of the study nickel and its alloys is characterised, in short, in historical, geological, economic and ecological aspects. However, the main issue tackled are this part of the study is to classify nickel alloys both in terms of the chemical composition (the type of main alloying additives), and the application under specific exploitation conditions. IN740 and H282 alloys were selected for the research. The results of which will be discussed in the second part of the article.
