Re: Residual stress measurement
youre work is very important, I a student of engeniering in the national institut of research nulear of mexico (INSTITUTO NACIONAL DE INVESTIGACIONES NUCLEARES)
MY WORK is development the relationship betwen barkhausen noise and the residual stress in steel ferrusmagnetic
I'd like information of the this topic

thaks

I would recommend that you check out any information that you can obtain from a vendor of equipment that uses this technology.

One such vendor is StressTech, and their website is http://www.stresstech.fi/.

Good Luck,
Norm

Re: Residual stress measurement
: : Does anyone know of any information about evaluation of
: : the residual stress on thin films (with or without substrate)
: : by using acoustic methods like acoustic microscopy?

:
: The following article is available on NDTnet.

: http://www.ndt.net/article/eschn/eschn.htm
: Nondestructive Characterization of State and Properties of Aluminium Structures
: By E. Schneider FhG IZFP

: Abstract:
: The contribution gives a short overview of IZFP investigations towards the process integrated characterization of microstructure and
: evaluation of mechanical properties. The propagation velocities of ultrasonic waves allow the evaluation of the elastic constants of the
: alloy and good correlations are found between the acousto-elastic constant of different alloys and their yield strengths. Using the
: times-of-flight of different ultrasonic waves, the residual stress states in plates and welded parts are evaluated. The texture in Al-sheets
: is determined and the earing parameter is characterized using measurements of ultrasonic times-of-flight as function of the ultrasonic
: propagation direction. Ultrasonic backscattering technique is applied to visualize the distribution of ceramic reinforcements in
: automotive pistons and conrods made of Al-based metal matrix composites. The volume content on reinforcement is evaluated from the
: ultrasonic velocities. Backscattering and time-of-flight measurements are used to visualize and to characterize the burrs in Al- hollow castings.

: Please use the NDTnet search engine and you may find other information as well.

Re: Residual stress measurement
: your work is very interesting, I am a worker of
engeniering in the Mexican Institut of Petroleum
(INSTITUTO MEXICANO DEL PETROLEO)

: My job is researching the behavior of the magnetic
materials (measurement of the residual stress), and
maybe can I use the Berhausen Noise or ultrasonic
method

: I'd like information of the this topic

: Best regards
