Study on diffusion behavior and microstructural evolution of Al/Cu bimetal interface by synchrotron X-ray radiography

Effect of traveling magnetic field on solute distribution and dendritic growth in unidirectionally solidifying Sn–50 wt%Pb alloy: An in situ observation

“…Though experiments of transparent organic alloys [9,[15][16][17] delivered valuable information for verification of solidification theories, these experiments do not really represent the situation in a solidifying metal alloys due to the differences in the thermophysical parameters. Now, synchrotron X-ray radiography with satisfying spatial and temporal resolution has become an important diagnostic tool for in situ and real time observation of solidification process in opaque metal alloys [18][19][20][21][22][23]. Only a few studies have been reported to study the effect of electromagnetically driven melt convection on the concentration profiles and the dendrite morphologies using X-ray radiography (synchrotron or laboratory source).…”

Effect of Annealing on the Interface and Mechanical Properties of Cu-Al-Cu Laminated Composite Prepared with Cold Rolling

“…As shown in Figure 4a, the thicknesses of the layers follow the sequence of Al 2 Cu > Al 4 Cu 9 > AlCu. As the diffusion of Cu in Al is faster than that of Al in Cu [3,20], Al 2 Cu is presumed to be formed more quickly than the phase of Al 4 Cu 9 . Therefore, the layer of Al 2 Cu is thicker than Al 4 Cu 9 .…”

3D Visualized Characterization of Fracture Behavior of Structural Metals Using Synchrotron Radiation Computed Microtomography

“…When the X-rays penetrate an object with multiple constituents, I(x) of the X-rays changes with the variable absorption coefficients of the constituents. Accordingly, absorption-contrast is obtained and the inner constituents of the object can be distinguished from each other, which is the imaging principle of CT [8][9][10]. Figure 1 shows the schematic diagram of the CT imaging principle in detail.…”
