Numerical modelling and in-situ radiographic study of …

11/6/2015· In a previous work [1], we have proposed a new grain size prediction model applicable for solidifiion of castings without recalescence. In the present work, an in-situ X-ray radiographic study on the grain nucleation and grain growth of inoculated Al-Cu alloys during isothermal melt solidifiion has been carried out, where the effect of melt convection is minimized.

FerroSilicon Market: Global Industry Trend Analysis 2012 …

Rising demand for ferrosilicon as a deoxidizer and inoculant across the various end-use industry is expected to have significant impact on the market growth over the near future. Electrical steel is also termed as silicon steel, and it utilizes significant amount of silicon and ferrosilicon, in order to improve the electrical properties of steel such as resistivity, etc.

Common Metallurgical Defects in Grey Cast Irons - …

Adding inoculant with the nodularising agent or during the reaction will significantly reduce the effectiveness of the inoculant and may result in increased carbides in the castings. In cases where it is necessary to add nodulariser and inoculant in the same ladle, the tap should be halted when about 2/3 of the iron has been poured onto the nodulariser.

1. Introduction

Though Sb is not a common additive in windmill DI castings, it is recommended in heavy section ductile iron castings because of its positive effect on graphite degeneration problem [8]. Therefore, another alloy D (double step, 0.5% inoculants) was cast where 0.02% of Sb was added intentionally to know the influence of Sb as a graphite antidegenerating element on the applicability of a DI alloy
