Grey Iron 1

[littleangel]

Just wondering if anyone can help. I need to do a university project on Grey Iron BS EN 1561:1997 just wondering if anyone can give me any tips on where to go about getting information. Kinda struggling a bit searching the web.

Thanx

You probably need to get a copy of the standard to review - should be available through your local library, or they can get a copy for you through an inter-library loan.

Try this web site

http://www.ironcasting.org/Gray Iron - A Unique Material.htm

Also check you libery for information form the "Grey and Ductile Iron Founders' Society"

They had a book called the Grey Iron Casters Handbook. This was na excellant book.

Hi,
Do you intend – a review paper, experimental research toward a degree..?
Do you have foundry and analytical facilities? Research money?

The following description is from British Standards Online (

http://bsonline.techindex.co.uk/):

BS EN 1561:1997 Founding. Grey cast irons
22 pages, £54.00 (non-member price).
“Descriptors: Foundry engineering, Production metallurgy, Castings, Grey cast-iron, Unalloyed cast-iron, Cast-iron, Thickness, Tensile strength, Hardness, Tensile testing, Test specimens, Dimensions, Proof stress, Elongation, Compressive strength, Yield strength, Strength of materials, Modulus of elasticity, Poisson ratio, Specific heat, Thermal expansion, Density, Thermal conductivity, Electrical resistivity, Coercivity, Permeability, Brinell hardness measurement, Symbols, Grades (quality).”

Seems like you have a wide selection of variables.

Casting Industry Trade Organization (looks like U.S. only) links, see

http://www.afsinc.org/AFSIS.htm

Online articles (

http://www.moderncasting.com/):

click on Modern Castings Archives, then Website Articles Archives. Several papers on gray iron.

Unfortunately, the Gray and Ductile Iron Founders' Society seems to have gone out of business. The Ductile Iron Society and Iron Casting Research Institute (links in above list) may be continuations of sorts.

The most recent editions of the book mentioned by unclesyd:
IRON CASTINGS HANDBOOK Covering Data on Gray, Malleable, Ductile, White, Alloy and Compacted Graphite Irons -- Walton, Charles F. , ed. (1981). 831 pages

GRAY AND DUCTILE IRON CASTINGS HANDBOOK: Including Data on Gray, Ductile, White and High Alloy Irons-- Walton, Charles F. , ed. (1971). 679 pages.

I have the 1971 edition. An excellent book, but it doesn’t mention non-US standards.

For an Internet search (277 journal articles):

Hope this helps. Also search with the ‘grey’ spelling, 336 journal articles!

P.S. Thanks to either TVP or TEV for first recommending the

search engine.

Ken,

Actually it was CoryPad that first mentioned Scirus. Quite the search engine, eh? Elsevier certainly has some incredible resources.

 

[JimMetalsCeramics]

Search under "Meanite".

The spelling on that is 'meehanite.'

Meehanite Metal (US)

http://www.meehanitemetal.com/

INTERNATIONAL MEEHANITE METAL COMPANY LTD(UK)

http://www.meehanite.co.uk/indexe.html

They make and license a full line of cast irons. Re Grey:

"The Metallurgy of MEEHANITE Flake (Grey/Lamellar) Iron

In the production of Meehanite flake graphite castings, the composition of the iron, whilst important, is only a part of the process for achieving a definite metal structure. The more important factor is mass, ie wall section thickness, and its effect on cooling rates. For normal cast iron, slow cooling (as in thick sections) produces a coarse open-grained, low strength structure, whereas fast cooling (as in thin sections) results in a hard, brittle, unmachinable structure. Thus in Meehanite practice, the structure of the metal and properties required are related to the section thickness of the casting."

"For more information on this subject why not email us and ask for a copy of the brochure: "MEEHANITE Flake Graphite Irons for General Engineering Applications""

If mehanite iron is your study subject,look at old issues of BCIRA a lot of references can be obtained. Also meehanite iron is essentialy a flake graphite iron having TypeA graphite in a pearlitic matrix. This is achieved by balancing the chemistry to get a pearlitic iron and using CaSi + FeSi as inoculants which ensure TypeA graphite morphology and its distribution in the matrix. section thickness of the casting also influences the mocrostructurewhich needs to be considered.
