Microstructural transformations and fatigue behavior of NDI-based polyurethane in response to extreme dynamic loads: A focus on hard segment content by Guangzhi Jin, Peng Li, Yuzhen Gong, Yu Wang, Runguo Wang, Fanzhu Li, Yonglai Lu

“…As the number of fatigue cycles increased, the applied load required to achieve the same strain decreased, primarily due to stress softening and plastic deformation in the CPU. Microstructural analysis revealed a reduction in hydrogen bonding degree, leading to a decrease in structural regularity and an increase in defects. …”

The Influence of Zn and Ca Addition on the Microstructure, Mechanical Properties, Cytocompatibility, and Electrochemical Behavior of WE43 Alloy Intended for Orthopedic Applications by Mircea Cătălin Ivănescu, Corneliu Munteanu, Ramona Cimpoeșu, Maria Daniela Vlad, Bogdan Istrate, Fabian Cezar Lupu, Eusebiu Viorel Șindilar, Alexandru Vlasa, Cristinel Ionel Stan, Maria Larisa Ivănescu, Georgeta Zegan

“…<i>Materials and Methods</i>: The WE43-Zn-Ca alloy system was developed by alloying standard WE43 (Mg–Y–Zr–RE) with 1.5% Zn and Ca concentrations of 0.2% (WE43_0.2Ca alloy) and 0.3% (WE43_0.3Ca alloy). Microstructural analysis was performed utilizing scanning electron microscopy (SEM) in conjunction with energy-dispersive X-ray spectroscopy (EDS), while the chemical composition was validated through optical emission spectroscopy and X-ray diffraction (XRD). …”

Effect of Cr addition on the hot deformation behavior and microstructure evolution of Cu-0.8Fe-0.2Mg alloy by Wenhao He, Ke Jing, Meng Zhou, Yi Zhang, Baohong Tian, Chunhe Chu, Jiangshan Cui, Haoyan Hu, Min Chen, Alex A. Volinsky, Bingbing Shang

“…The established constitutive equations revealed that the activation energy of the Cu-0.8Fe-0.2Mg-0.2Cr alloy was 16.84 % higher than that of the Cu-0.8Fe-0.2Mg alloy. Microstructure analysis demonstrated that the addition of Cr decreased the percentage of high-angle grain boundaries (HAGBs), which inhibited the dynamic recrystallization (DRX) of the Cu-0.8Fe-0.2Mg-0.2Cr alloy. …”

Investigation of the microstructure evolution of 7CrMn2WMo economy‑alloyed steel in a new design forging tool implementing shear deformations by S. N. Lezhnev, A. B. Naizabekov, I. E. Volokitina, E. A. Panin, D. V. Kuis, I. N. Stepankin

“…A comparative analysis of the results of the microstructure evolution when forging blanks made of 7CrMn2WMo steel according to the proposed and current technologies proves the usefulness of a new design tool instead of the currently used flat strikers, since forging in the proposed forging tool provides more intensive and uniform processing of the cast structure over the entire section of the workpiece compared to forging in the flat strikers.…”
