Microstructure and failure mechanism of FGH96 solid-state diffusion bonding interface by YANG Jie, LIU Guang-xu, ZHANG Jing, WANG Wen-ying, WANG Xiao-feng, ZOU Jin-wen

“…Results of the electron backscattered diffraction (EBSD) show that the preferred orientation of large grains is {100}, and the grain orientation is more obvious as the closer distance to the solid diffusion interface. …”

Influence of adjustable ring modes on molten pool behavior and microstructure of Al–Si coated boron steel in fiber laser welding by Hyun-Uk Jun, Jooyong Cheon, Yeong-Do Park, Yang-Do Kim, Changwook Ji

“…The RBM and DBM effectively suppressed Al segregation into the FZ, leading to a reduction in ferrite formation and the development of a refined microstructure characterized by a uniform and high density of geometrically necessary dislocations. Electron backscattered diffraction (EBSD) analysis revealed a higher proportion of low-angle grain boundaries in the RBM and DBM, attributed to the unique thermal distribution induced by the ring beam. …”

Strength-ductility synergy through microstructural and compositional heterogeneity in directed energy deposition additive manufacturing of face-centered cubic materials by Md R.U. Ahsan, Nadim S. Hmeidat, Saiful Islam, Xuesong Fan, Jonathan D. Poplawsky, Peter K. Liaw, Yousub Lee, Brett G. Compton, Yongho Jeon, Duck Bong Kim

“…The formation of a bamboo-like alternating microstructure was confirmed through electron backscattered diffraction (EBSD) analysis. Hardness mapping showed that the columnar to equiaxed transition (CET) occurred at the region right below the fusion line. …”

Achieving strength-ductility synergy of spark plasma sintered (CoCrNi)94Al3Ti3 medium-entropy alloy via post-sintering in-situ precipitation treatment by Shifeng Luo, Nan Wang, Yan Wang, Xiang Li, Xiaogang Fang, Hongwei Zhou, Jieming Chen, Xinyu Yang, Jiuxing Zhang

“…A high tensile yield strength of 1141 MPa with an adequate elongation to fracture of 25.8% was achieved in (CoCrNi)94Al3Ti3 MEA after annealing at 700 °C for 4 h. Electron backscattered diffraction and transmission electron microscopy characterizations indicate that the superior mechanical properties mainly originate from fine grains and the coherent spherical L12 precipitates. …”

Studies on the retarded recrystallization of tungsten in CIMPLE-PSI exposed under very-high target temperature and long He+-fluence by Mizanur Rahman, Sabir Chetri, S.H.B. Teo, M. Thompson, M. Bilokur, C. Corr, S. Shekhar, G.De. Temmerman, Mayur Kakati

“…Exposed samples are characterized by field emission scanning electron microscopy (FESEM), Vickers surface micro-hardness, nano-hardness and electron backscattered diffraction (EBSD). It is observed that the sample exposed to plasma under the highest temperature (1866 K) suffered acute retarded grain growth. …”
