Crystallization of nodular cast iron with carbides
Theory of crystallization TDA method Nodular cast iron with carbides
2011/3/17
In this paper a crystallization process of nodular cast iron with carbides having a different chemical composition have been presented. It have been found, that an increase of molybdenum above 0,30% c...
The sort of carburization and the quality of obtained cast iron
Theoretical bases of foundry processes Cast iron Carburization Carburizers
2011/3/17
In the production of cast iron, the pig iron’s amount in charge material is more and more often limited, and replaced by steel scrap. That extorts the necessity of know-how the carburization and one i...

Effective inoculation of low-sulphur cast iron
Inoculation Cast iron Dendrites Structure Mechanical properties
2011/3/17
The study proves that by introducing the disintegrated steel scrap to low-sulphur cast iron still before the inoculation carried out with a conventional graphitising inoculant, the mechanical properti...
Purpose: Thixoability of the ASTM A536 nodular cast iron is analyzed, it meaning its ability to hold a thixotropic semi-solid state and to be formed as such. Thixoability can be characterized by the s...
Influence of copper on effects of precipitation hardening of ductile cast iron
Copper ductile cast iron Precipitation hardening
2011/3/15
Ductile cast iron with different copper content was precipitation hardened. Cast iron with 0.48 % Cu content was ferritized. That operation was ended with rapid quenching, and then aged. Cast iron wit...
