Hello, I'm trying to calculate the bursting pressure of a pipe cap or the end capped pipe. I need to know how much pressure will cause the cap of the pipe to burst or deform. I have the bursting pressure of the pipe, so its the cap bursting pressure I need to calculate Here is a crude...

Thank you Dav2008, At present, I am attempting to load the pipe like this ->||<- The pipe length as such does not really play much a part but the length should be at least a feet long. I am trying to overcome the buckling that occurs on the side of the pipe as it is compressed as these areas...

Hello, Does anyone know how to calculate the cross sectional compressive strength of a piece of pipe? I know as you compress or crush the pipe along the cross section of the pipe it will strain harden at which point compression will be unable to continue experimentally. I need to know what...

Hi, Could anyone please give me a definite difference between precipitates, dispersoids and intermetallics? I would appreciate any references to descriptions and definitions. Thank you so much

WC (Hard tools) are good substrates for diamond coatings. The meet all the requirements for this sort of coatings. They are coated by a CVD process and loads of research has gone into this area. Hot Filament CVD has been used. You can also look into the paper 'Interaction of hard metal...

Hello, I would like to know how one can confirm that a material is diamond apart from confirming its crystal structure. I tried the copper cooling test and it passed, are they any other tests to confirm? What acid test would be best to confirm? Thank you

Hi, It's come to my attention that one can use glass as a lubricant for hight temperature metal working operations. I'm very interested in this could anyone please give me any information about this, papers, articles and book references as well as a company I can get these glass coatings...

I'm looking into using Tungsten disulfide as a lubricant in the form of a thin metal coating. Now I've been made to understand that it can be applied by various methods i.e burnishing, impingement and pulse laser deposited. From what I gather the method of applying this solid lubricant...

Thanks Chemistree as I said early my main focus is on sintering. Mostly on abnormally large grains (grain growth) during sintering and how particle packing, size and distribution affect densification. Thanks

Thanks again. Alright could I get any papers or information with regards Abnormally large grains (grain growth) during sintering and how particle packing, size and distribution affect densification. Or a literature review article on sintering. I have a bit of information on both but...

Thanks, the paper and book have been quite useful. I did observe though that the book quotes mostly papers older than 1980. I was wondering if I could pick your brains with regards current sintering procedures and technology? If that isn't too much to ask.

Thanks ever so much. The book looks quite helpful. Would you mind if I take advantage of your deep knowledge of Ceramic processing and ask for a good paper or book that talks on sintering kinetics, densification kinetics and coarsening kinetics and grain growth control. Thanks so much

Thanks again. I've tried using the book seems rather old, published 1990. I'm looking for developments since then. The first chapter though was pretty helpful, anything moving on from there would be perfect. I'm looking for developments in fundamentals of collodial processing basically...

This is unchartted waters for me so not so sure about that but I believe the should be a difference. I am more interested in the research findings with regards fundamentals I think like powder consolidation and densification and grain growth hindering and the likes. Develepoments in such...

Ceramic Powder processing progress - urgent Hey there, Would really appreciate some urgent help here more like direction. I'm looking into the progress of colloidial ceramic powder processing and am getting a bit confused. Could anyone point me as to any good papers that could help me...
