Definition[edit]

Sintering of powdered metals requires an organic "forming" compound to be mixed with the steel alloy which is pressed in a form, usually in a vacum furnace, at very high heat 2000deg or so, this may vary. The high heat burns out the forming material. Sintered metals then require a traditional heat treating process, since the high heat makes the grain structure do some crazy things.

Mergeable information[edit]

From the article "sinter":

Sinter is a material charged to the Blast Furnace in the Ironmaking Process.
It consists of fine iron ore fused at high temperature with fluxes to form a porus clinker, which is later charged to the blast furnace.
Sintering takes place in a Sinter Plant, sinter plants are also used to recycle waste material generated elsewhere in the steelmaking process.

This material should be checked out and merged in by someone with more expertise in the field than I. -- 71.48.151.56 01:23, 11 June 2006 (UTC)

Copyvio[edit]

I removed the whole section on microwave sintering, as it seems to be a copyright violation. See the original. --Slashme 13:27, 26 September 2007 (UTC)

Frit[edit]

What's the difference between fritting and sintering? --Ayacop (talk) 06:36, 29 July 2008 (UTC)

That equation[edit]

I don't believe it. It implies that maximally dense iron (D = d) has tensile strength equal to its elastic modulus, which is ridiculous. What's the source for it? -- 99.140.63.214 (talk) 10:37, 3 August 2008 (UTC)

... materials with high melting points such as Teflon and tungsten[edit]

Tungsten melts at 3695 K. Teflon has a melting point at around 600 K. Can we really write that Teflon has a high melting point and even compare it to tungsten. I did not edit the sentence myself, because maybe Teflon's melting point can be considered high for the purpose of sintering. Can anyone clarify this matter? --193.40.245.26 (talk) 10:01, 2 February 2009 (UTC)

I see where you are coming from, the sentence is poorly worded. However, the point is correct, with the point being that tungsten and teflon cannot be easily manufactured using "standard" processes that are common for either of them. I.e. teflon has a high melting temperature for plastics and tungsten has a high melting point for metals. But again, it really needs to be reworded to remove the ambiguity.

There, I tried to reword it in a less ambiguous way. Let me know what you think. Wizard191 (talk) 16:53, 5 February 2009 (UTC)

Proposed merge from pressureless sintering[edit]

Pressureless sintering is a stub that I don't foresee growing too much bigger, so I think it makes sense to merge it into this parent article. Wizard191 (talk) 19:06, 10 September 2009 (UTC)

I agree. --John (talk) 22:01, 10 September 2009 (UTC)

General Sintering[edit]

I changed (p0)2/3 and (p0)1/3 to (p0)2/3 and (p0)2/3, because I assumed that was meant to be a subscript 0, indicating the initial state; p0 evaluates to 1 and is a meaningless statement. Note that I'm still not sure exactly what quantity p0 is supposed to represent, though. The source cited immediately after is a book, so I can't readily check. 131.151.66.22 (talk) 03:47, 18 November 2010 (UTC)

Snow sintering[edit]

Sintering is the mechanism that allows powder snow to be packed. Compressing snow and waiting for it to sinter is part of building a quinzhee. Source. I didn't see a good place to put this, but it should be covered here. Jokestress (talk) 09:06, 9 January 2013 (UTC)
