“…This is critical when examining delicate samples that cannot be easily sectioned or those ought not to be damaged (e.g., structural integrity check of engineering components before deployment, such as a turbine blade). The non-destructive aspect also opens up the possibility of in situ monitoring of microstructural evolution, leading to a wide range of applications for the SR-CT technique in terms of static/dynamic 3D characterizations of dendrites morphology [55][56][57], intermetallic compounds [58][59][60], precipitates [61][62][63], the spatial distribution of voids [64][65][66][67][68] and inclusions [69,70], crack initiation [71][72][73][74][75][76][77][78], propagation [39,[79][80][81][82][83][84][85][86], and fracture [87][88][89][90][91][92][93]. Later, chapters will be discussing material preparation and mechanical performance in terms of different imaging techniques, namely, 2D imaging, 3D imaging, and in situ imaging.…”

Characterizing the microstructure and deformation mechanism associated with the performances and properties of metallic materials is of great importance in understanding the microstructure-property relationship. The past few decades have witnessed the rapid development of characterization techniques from optical microscopy to electron microscopy, although these conventional methods are generally limited to the sample surface because of the intrinsic opaque nature of metallic materials. Advanced synchrotron radiation (SR) facilities can produce X-rays with strong penetrability and high spatiotemporal resolution, and thereby enabling the non-destructive visualization of full-field structural information in three dimensions. Tremendous endeavors were devoted to the 3rd generation SR over the past three decades, in which X-ray beams have been focused down to 100 nm. In this paper, recent progresses on SR-related characterization technologies were reviewed, with particular emphases on the fundamentals of synchrotron X-ray imaging and synchrotron X-ray diffraction, as well as their applications in the in situ observations of material preparation (e.g., in situ dendrite growth during solidification) and service under extreme environment (e.g., in situ mechanics). Future innovations toward next-generation SR and newly emerging SRbased technologies such as dark-field X-ray microscopy and Bragg coherent X-ray diffraction imaging were also advocated.

“…Another phenomenon that requires the analysis of three-dimensional microstructures is, investigating the continuity of a second phase in metallic alloys. Reviews by Kostenko et al [4] have shown that the cementite carbide phase has to network continuity in low carbon steels and heat treatments such as spherodization also affect the morphology and continuity of them. In recent years, many researches have been done in the field of three-dimensional metallography for studying the microstructure of steels [4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”

We developed a three-dimensional microstructure analysis system based on the manual serial sectioning method to evaluate the heat treatment effects on chromium carbide size and morphology in AISI D2 tool steel. Two heat treatment factors, austenitizing and tempering temperature were investigated. The results show that increasing in austenitizing temperature leads to further carbide precipitation after the tempering process and increasing in the tempering temperature causes precipitate smaller secondary carbides even more than the primary carbides.

“…X-ray PCI found applications in materials science, ranging from investigating the microstructure of carbon-based materials [1,2] to in-situ measurements of dynamic processes taking place in metal alloys and semiconductors [3][4][5]. X-ray PCI is also entering the field of pre-clinical biomedical research, namely, small animal imaging and various ex-vivo/in-vitro studies [6][7][8][9][10][11].…”

State-of-the-art techniques for phase retrieval in propagation based X-ray phase-contrast imaging are aiming to solve an underdetermined linear system of equations. They commonly employ Tikhonov regularization − an L2-norm regularized deconvolution scheme − despite some of its limitations. We present a novel approach to phase retrieval based on Total Variation (TV) minimization. We incorporated TV minimization for deconvolution in phase retrieval using a variety of the most common linear phase-contrast models. The results of our TV minimization was compared with Tikhonov regularized deconvolution on simulated as well as experimental data. The presented method was shown to deliver improved accuracy in reconstructions based on a single distance as well as multiple distance phase-contrast images corrupted by noise and hampered by errors due to nonlinear imaging effects.
