effect of temperature on AE

I need information about the effect of temperature on acoustic emission ( velocity, attenuation). i have found only one article from Mr ONO.
have anyone idea about this subject and where can i find information.

thanks,

Also I want to know that this method can be used for materials in furnaces at high temperatures
Regards.

Re: effect of temperature on AE
Hi,
with increasing temperature velocity usually goes down and attenuation increases.
For measurements in a furnace you either need high-temp sensors (e.g. up to 500°C) or so-called waveguides (e.g. a strong wire) which are acoustically coupled to your sample and transfer the waves out of the furnace that you can pick them up with standard sensors at room temperature.
regards
Jens
