Surface layer inoculation of a sand cast hypoeutectic …
2015/6/1· The surface layer metallurgy was applied to achieve a cost-effective in-mold inoculation of a hypoeutectic gray cast iron melt (CE = 3.7%) with low silicon and sulfur contents: In all cases, the suspensions lead to complete inoculation of the gray iron melt resulting in a homogeneous microstructure devoid of cementite and fulfilling the hardness requirements of the gray iron standard …
Metallurgical Process Control for Compacted Graphite Irons
Technical Introduction / Metallurgical Process Control for Compacted Graphite Irons General Introduction Compacted (Vermicular) graphite irons (CGI) have been produced since the inception of spheroidal graphite (nodular or ductile) irons in the late 1940''s. Invariably
From Metallurgy to Optimized Casting Properties - …
The quality and profitability of iron castings are driven by the metallurgy of the melt, the design of the pattern, the productivity of the process, reproducible manufacturing conditions and the resulting properties of the cast iron material after casting and heat treatment.

In addition, inoculation and fading effects were considered in the experimental outcome. Accordingly, the graphite nucleation coefficients, N s , b, the eutectic cell growth coefficient, μ, and the critical cooling rate, Q cr , for the development of eutectic cementite (chill) were all determined as a function of the cast iron chemistry and time after inoculation.
Inoculation is an established process not only for preventing carbide formation, but also for the control of graphite flake size and form in grey cast iron. After a brief consideration of the various theories advanced regarding inoculation, this paper reviews some of the developments that have taken place in inoculants and inoculating procedures for flake graphite cast iron.
