Thin Wall Ductile Iron Castings as Substitutes for Aluminium Alloy Castings

Undercooling and nodule count in thin walled ductile iron castings

Effect of Melting Techniques on Ductile Iron Castings Properties

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...

The filtration of large grey and ductile iron castings

Filtration of mass produced automobile castings is widely and successful applied, less common and more difficult is the filtration of large castings heavier than 1.000 kg. The paper deals with the special problems of applying filtration to such castings including; filter selection, description of three special filtration gating system concepts, along with ten case studies are given.

Experimental validation of error in temperature measurements in thin walled ductile iron castings

Porosity Prediction in Aluminum A356 Alloy Castings

A comprehensive methodology that takes into account alloy solidification, shrinkage-driven interdendritic fluid flow, hydrogen precipitation, and porosity evolution has been developed for the prediction of microporosity fraction in aluminum A356 alloy castings. The mathematical models presented are implemented in a computational framework consistent with those of commercial casting codes, allow...
