Cast iron is a very common and useful metal alloy, characterized by its high carbon content (>4%) in the allotropic state of graphite. The correct shape distribution graphite are essential for ensuring that material has right properties. present investigation examines metallurgical mechanical characterization spheroidal (nodular) cast iron, an alloy derives name excellent properties from pre...

The early Cambrian Takab iron ore deposit is situated in the northern part of Sanandaj-Sirjan zone, western Iran. It consists banded, nodular and disseminated magnetite hosted folded micaschists. Trace element Fe O isotopic experiments reveal various hydrothermal precipitation environments under reduced to slightly oxidizing conditions. Disseminated has high Ti (945–1940 ppm) positively correla...

in this research, effect of the number of nodular graphite particles, as an important characteristic of ductile cast irons, on the distribution of martensite in dual-phase ductile iron has been studied. ductile iron samples were produced by step casting and the samples were then annealed in order to achieve a fully ferritic structure. a special heat treatment was conducted to produce dual matri...

Ductile iron is one of the most important engineering materials, in view of its excellent castability, signifi cantly better mechanical properties and low cost [1, 2]. It represents the fastest growing segment of the iron market. In the medium term, it is to be expected that the market share of nodular iron will level off at 40 % to 45 % [3]. Achieving the full potential of ductile iron require...
