Weldability of spheroidal graphite cast iron

Welding International, 2000
The weldability of a spheroidal graphite cast iron of a established chemical composition is analysed. Metal Are Welding (MAW) and Oxyacetylene Welding (OAW) have been used on casting samples of 300 x 900 x 10mm, with a groove angle of 60°. It is also analysed the influence on the weldability of the chemical composition of the different electrodes used,

Elimination of Chunky Graphite in Castings with Large Thermal Points

Archives of Foundry Engineering, 2016
The presence of the chunky graphite is unwanted in the cast iron with the spheroidal graphite for this significantly lowers the properties of the ductile iron.

A 2-D nucleation-growth model of spheroidal graphite [PDF]

, 2017
Analysis of recent experimental investigations, in particular by transmission electron microscopy, suggests spheroidal graphite grows by 2-D nucleation of new graphite layers at the outer surface of the nodules. These layers spread over the surface along

Effects of Manganese and Heat Treatment on Mechanical Properties in Spheroidal Graphite Cast Iron

International Journal of Metals
It is well known that the mechanical properties of spheroidal graphite cast iron deeply depend on the volume of pearlite matrix microstructures. Therefore, the theoretical criterion of pearlite matrix nucleation is considered important in this graphite ...

Experimental and FEM Studies of Continuous Drive Friction Welding of Ferritic Spheroidal Graphite Cast Iron

Processes
Experimental and FEM studies of the friction welding process of spheroidal graphite cast iron (SGCI) are presented. A coupled thermal and mechanical 2.5 D FEM model was used to simulate the continuous drive friction welding (CDFW) process.
