Does anybody know how to detect small non metalic inclusion ( 0,010 mm to 0,020 mm ) into steel ( X51CrMo3 or X51CrMoV5-1 ). Steel thickness 0,5 mm Détection on the surface and in the volume.

A radiographic linear array system should be able to detect these indications. Lixi Inc. has some experience with these systems. Their website is www.lixi.com

You can also investigate the possibility of a laser ultrasonic system. Expensive but able to detect high frequency ultrasound. (www.tecnar.com) With Ghz ultrasound, I was able to measured thickness foil down to 10um. regards, Francois

Re: Detection of small nonmetallic inclusion Envision's high resolution digital X-ray panels and linear arrays along with a micro-focus source will image your inclusions in the 10 to 20 micron range. http://cmosxray.com

Magnetic Leakage Flux method can be one of the possible candidates, which is good since it is a noncontact method, and no couplant is needed. I have done a similar research, which is very easy to apply. The detectivity of the nonmetallic inclusion can be down to 1x10^(-4) mm^(3), or better than that in some cases. There can be some limitations.
1. Surface condition 2. Uniformity of the inner material structure
The thickness of 0.5 mm can be a problem. But you can access from both sides (top and bottom).
If you have any question, then we can discuss further.
