Consequently, auxiliary deformation mechanisms, such as twinning, are activated to accommodate and promote plastic deformation.

Due to its extremely low coefficient of thermal expansion along the fiber axis, the uniformly distributed felt significantly reduced the cooling shrinkage deformation of the brazed seam. As a result, finite element simulations predict that the simulated equivalent plastic strain at the brazed seam is reduced by 26.4%, and the simulated maximum principal residual stress at the G/brazed seam interface is reduced by 25%.

Although metal doping has been widely employed to improve structural stability, the quantitative relationship between dopant-induced phase evolution, reaction kinetics, and long-term durability remains unclear. Here, seven metal dopants (Zr, Mn, Ce, Ni, Fe, Cr, and Co) were incorporated into CaO to systematically evaluate their influence on multiscale reaction behavior. Among them, Zr-modified CaO exhibits superior cyclic stability, retaining more than twice the CO<sub>2</sub> uptake of pristine CaO after 40 cycles. Structural analyses (XRD, BET, SEM) reveal that Zr promotes the formation of a thermally stable CaZrO<sub>3</sub> phase that acts as a refractory skeletal/spacer phase to mitigate morphological densification and preserve pore connectivity. Isoconversional and pressure-corrected kinetic analyses show that Zr stabilizes the apparent activation energy across the full conversion range and maintains a consistent phase-boundary-controlled mechanism, thereby delaying diffusion limitations during cycling.
