Summary: The compressive residual stress (CRS) introduced by ultrasonic surface rolling process has been proven to be effective in improving the fretting fatigue (FF) life of materials, particularly in extending the crack propagation life. However, it has less contribution in prolonging the crack initiation life. Additionally, for Ti-6Al-4V titanium alloy, FF crack initiation is characterized by multiple sources and easy nucleation.

Summary: Ultrasonic rolling is an advanced non-cutting surface strengthening method that combines traditional rolling with ultrasonic vibration. In this research, the surface integrity refactoring changes and mechanism of Ti-17 titanium alloy during the milling-ultrasonic rolling composite process were studied and analyzed. The results showed significant improvements in surface integrity indicators after ultrasonic rolling. The reduction effect of surface roughness by ultrasonic rolling process is inversely proportional to the initial surface roughness value. The improvement effect of ultrasonic rolling on surface compressive residual stress and microhardness decreases with the increase of initial milled surface roughness and surface compressive residual stress.

Summary: Carburizing combined with ultrasonic surface rolling (USR) was used to reduce the wear rate and coefficient of friction (COF) of a new type gear steel. The microstructure, microhardness, surface morphology, and tribological behavior were studied. The results showed that the combined treatment generated an average surface particle size of 6.67 μm, a microhardness of 918 HV0.2, and a maximum surface compressive residual stress of -468 MPa. The wear rates of carburized specimens and specimens treated with the combined process were 3.16 x 10-15 m3/Nm and 2.98 x 10-15 m3/Nm, respectively. Furthermore, the wear mechanisms differed, with carburized specimens exhibiting three-body wear and specimens treated with the combined process mainly showing adhesive and oxidative wear.

Summary: In this study, a novel class of two-dimensional trimetallic MOF nanosheets with abundant active sites and facilitated mass and electron transfer channels was developed as efficient electrocatalysts for boosting oxygen evolution reaction (OER). The unique 2D nanosheet structure enlarged the active area, and the organic ligand in the MOF served as a pillar to enlarge the interplanar space for ion and electron transportation. The synergistic effect between multi-metal active sites effectively promoted the electrocatalytic activity. After an electrochemical activation process, the optimized NiFeZn MOF nanosheets showed outstanding OER performance with low overpotential and small Tafel slope. This method is also universal for the synthesis of the NiFe-MOF family.

Summary: Studying the mechanical property of nanomaterials is challenging due to the difficulty in handling them and applying force. However, a convenient alternative method using electrospun fibers has been demonstrated to align silver nanowires and study their stretching behavior. The results show that the necking phenomenon in stretched nanowires is dependent on the wire diameter rather than the degree of stretching, indicating a unique limiting state achieved by the nanomaterials. Advanced microscopy and molecular dynamics simulation reveal that dislocations and stacking faults contribute to trapping the necks at these limiting states.
