... be taken in the field. A common tool for PMI of alloys in the field is a portable XRF analyzer. This handheld device can provide information in minutes and use databases to match the spectra to an alloy ( Fig. 1 ). This method is nondestructive to the part, but usually requires safety precautions because...

.... Safety precautions were taken to avoid the inhalation of mercury fumes during removal of the samples. Intergranular cracking was the preferred mode of failure in the weldment and was also reflected in the exfoliation type of attack that ran parallel to the pipe walls. This type of behavior is similar...

Another example of a difficult plating removal process would be a copper/nickel/chromium plating on a zinc die casting. Since the zinc is more soluble in acid than any of the plating layers, another approach is obviously...
