“…When X-rays generated by synchrotron radiation pass through the sample, the contrast is produced because of the differences in X-ray attenuation of different structures. Then, the value projection image with structure information is obtained by CCD (charge-coupled device) [18][19][20]. For Mg alloys, the synchrotron radiation X-ray radiography imaging is often used to characterise the evolution of morphology of solidified structure.…”

The synchrotron radiation technology is a powerful tool for characterisation of the microstructure of alloys because of its strong penetration, high resolution and non-destructiveness. Mg alloys are widely used in engineering due to their low density, high ratio strength and good casting properties. The application of synchrotron radiation techniques in characterising the microstructure in various Mg alloys has made incremental progress. The present review introduces the basic principles of synchrotron radiation techniques, and summarises recent advances in the application of these techniques in understanding the solidification microstructure, deformation behaviour, phase transformation mechanism, hydrogen storage capacity, long-period stacking ordered structure of Mg alloys. The perspective on the development and further application of synchrotron radiation technology for alloy research is also discussed.

“…On the other hand, the diffraction signal usually contains lattice distortion information, which can be used to calculate the lattice stress or assess the dislocation density in the material. structural information is obtained from the back-projected grayscale/intensity profiles [45]. Synchrotron radiation computed tomography (SR-CT), including absorption contrast and phase contrast modes, provides rich information of the internal structure of materials non-destructively at scales from meters down to tens of nanometers [46][47][48].…”

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.

“…Comparing to other bimetal bonding processes, the solid-liquid bimetal compound casting has been extensively used in modern industry with the advantages of good interfacial bonding quality, high production e ciency and wide range of applicable alloys, etc. [4][5][6][7]. For instance, the most typical application of this process in automotive is the manufacturing of aluminum engine cylinder block with cast iron liners.…”

A practical bimetallic casting consisting of aluminum matrix and cast iron inserts was manufactured via high pressure die casting (HPDC) process. Different surface treatment methods of the cast iron inserts, including salt membrane plating and electrogalvanizing, were adopted to improve the bonding quality of bimetallic castings. Microstructure characterization on the bonding interface was conducted at different locations of bimetallic castings. Results indicate that compounds with awless and continuously metallurgical bonding interface can be successfully fabricated by the HPDC process with the zinc rack plating treatment on the surface of cast iron inserts which results in a dense zinc coating with an average thickness of 8 μm. The melt ow speed and heat transition during solidi cation of the HPDC process are two key factors in determining the bonding integrity of bimetallic castings. With the dissolution and diffusion of the very thin zinc coating during solidi cation, there is no obvious aggregation of zinc element at the metallurgical bonding interface. Instead, a reaction layer with an irregular tongue-like morphology is formed with an average thickness of approximately 1 μm while it mainly consists of intermetallic phases Al 60 Cu 30 Fe 10 and Al 2 FeSi, etc.
