主 题：X-ray KES imaging Grayscale calibration Element analysis for alloy Nondestructive imaging of elements
摘 要：Doped elements in alloys significantly impact their *** methods usually sputter the surface material of the sample,or their performance is limited to the surface of alloys owing to their poor penetration *** X-ray K-edge subtraction(KES)method exhibits great potential for the nondestructive in situ detection of element contents in ***,the signal of doped elements usually deteriorates because of the strong absorption of the principal component and scattering of crystal *** in turn prevents the extensive application of X-ray KES imaging to *** this study,methods were developed to calibrate the linearity between the grayscale of the KES image and element *** methods were aimed at the sensitive analysis of elements in ***,experiments with phantoms and alloys demonstrated that,after elaborate calibration,X-ray KES imaging is capable of nondestructive and sensitive analysis of doped elements in alloys.
