Introduction Joining is critical to the fabrication of structures and devices for use in aerospace, biomedical, chemical, electronic, mining, and other applications.
Joining also has the potential to allow repair of damaged structures through the replacement of defective components, thereby extending assembly lifetimes, and permitting the reuse of costly nonrecyclable components, e.g., fiber-reinforced materials.
Components can be temperature-sensitive due to extremely fine-scale structures (e.g., dispersionhardened alloys and other nanoscale microstructures) that degrade or coarsen during high temperature exposure, or due to components that decompose or degrade above specific threshold temperatures (e.g., glassy metals and polycrystalline diamond coatings).
Diffusion of the cladding material into the core layer and counterdiffusion of alloying elements in the core layer will eventually homogenize the interlayer, and can bring to the interlayer/ceramic interface elements that affect the interfacial chemistry and adhesion.

Introduction Among the various types of lithium-ion batteries (LIBs), lithium iron phosphate (LiFePO4 or LFP) is poised to become one of the most widely used cell chemistry types in electric vehicles (EVs) due to its thermal stability, reliability, low cost, safety, and long cycle life [1–3].
Hence, the key to effectively regenerate LFP is to dose Li ions into the crystal structure and reduce Fe3+ to Fe2+.
The bands at 471 and 500 cm-1 can be attributed to the translational vibrations of Li ions near neighboring oxygen atoms in the olivine LiFePO4 structure [20].
Furthermore, in the XRD patterns of re-lithiated LFP at 180 °C for 5 h, the peaks corresponding to the plane reflections of the olivine structure were observed, without any impurity peaks.
Structural and compositional analyses, including XRD, FTIR, SEM, EDS, and ICP-OES, confirmed the effective restoration of the LFP crystal structure and lithium content.

It was show that compact substrate and weak interface enhance the strength, and porous structure improvesthe dielectric performance of the composite.
The polyborosilazane (PBSZ) and polyborazine (both from Institution of Chemistry Chinese Academy of Science) are used as the precursor of ceramic matrix and coating, respectively.
It can be seen from Fig. 8(c) that the composite has porous structure with an apparent porosity of 20% (by Archimedes law) and a density of 1.97.
Compact substrate (Fig. 8(d)) enhances strength and porous structure improves dielectric performance of the composite.

It can be seen from them that the surface of particles in roasted products is rough and the structure of particles is loose.
It indicates that under alkali conditions, with increasing temperature, the intact structure of minerals in the shale is broken down gradually.
NaOH can react with the minerals such as quartz, potassium feldspar and muscovite in the sample by roasting to make crystalline structure in them broken down to a certain extent.
Qi et al. (2004) believes that when the silicate and aluminosilicate are roasted with alkali, with increasing temperature, solid phase reaction is faster and the skeletal structure of Si and Al is broken down.

Coating structure was investigated using XRD.
By applying heat treatment, structure of the coating changes from amorphous structure to crystalline.
But unfortunately up to date, only limited investigations have been conducted on the effects of heat treatment and nanocrystallined structure on corrosion properties of Ni-B-W coatings.
At this temperature, the phase transformation from amorphous to a crystalline structure is detected.
