Talk:Shape-memory alloy

The data in this page has been transferred from the Memory metal article (apologies if this was the wrong way to move them). The original author info is still stored under the memory metal history. Average Earthman 11:05, 9 Dec 2004 (UTC)

Nanowires?

I went to a fascinating talk recently by Min Zhou of Georgia Tech who is researching unexpected memory behavior in nanowires of regular materials such as copper. I'm not sure if this disserves mention in the article yet, but it should be kept in mind. Basically the small scale (~5×5 atoms) allows dislocations to not interfere and so the crystal orientation of a nanowire can be switched back and forth under axial strain and temperature changes. —BenFrantzDale 01:44, 21 October 2005 (UTC)

Plot...

I believe the plot of the martensite/austenite ratio dependence on temperature is wrong. I agree that a similar plot can be obtained by plotting deformation versus temperature, when an SMA actuator work against eg. a constant load. In that case the backslash can easily be explained by the deformation treshold. I make this claim, because I made several measurement of resitance and radiation heat, and data suggust that the relation is semidefinit.

Manufacture and Uses

Where have the sections gone, there appear just to be 3 titles but with nothign underneath them. has the page been vanadalized or something similar?

Are Raychem the pioneers in this field

In an interview with Paul Cook (Harvard business review March-April 1990) Paul Cook of Raychem claimed that the Naval Ordinance Lab had begun the research and that Raychem developed the heat shrinkable plastics. Back in 1970. Page 105 HBR March - April 1990.

PS. Raychem was acquired by Tyco

Can somebody fix the first line of this article please, I can't seem to do it, but you know what I'm talking about.

I think this page needs to be cleaned up a bit in terms of understandable language. Its first paragraph is confusing in its language. 66.16.162.134 14:48, 18 December 2006 (UTC)

Manufacture section?

Doesn't make sense, particularly the part about 500 degrees for more than 5 minutes, which seems to contradict the previous line. Very bare paragraph that doesnt seem necessary. Also I think the medical applications could be talked up a bit more seeing as thats where most of the revenue will come from. Clot filters, stents, guidewires, and why they are suited to these applications. I would do it, but I just don't have the time, and when I do, I won't have the internet :( Howboutpete 02:18, 30 May 2007 (UTC)
