Contribution of ultrasonic surface rolling process to the fatigue properties of TB8 alloy with body-centered cubic structure

Dan Liu et al.

Summary: The ultrasonic surface rolling process (USRP) was found to significantly enhance the fatigue strength of TB8 alloys by creating gradient structure surface layers through multiple passes. However, the improvement in fatigue strength compared to other titanium alloys was limited due to notable surface residual stresses relaxation. Fatigue crack initiation was observed in larger grains on the surface, with subsequent propagation in a mixed transgranular and intergranular mode. Grain growth and reduction in geometrically necessary dislocations value were identified in post-fatigued USRP-treated TB8 samples.

Investigation of Two-Dimensional Ultrasonic Surface Burnishing Process on 7075-T6 Aluminum

Zhenyu Zhou et al.

Summary: A novel two-dimensional ultrasonic surface burnishing process (2D-USBP) is proposed for processing 7075-T6 aluminum samples, with parameter optimization determining the best processing strategy. The study establishes active control models for surface quality and conducts dry wear tests, showing that the machining quality of 2D-USBP is best under specific parameters. Wear mechanisms are analyzed under different loads, with the 2D-USBP treated sample demonstrating improved wear-resistance and surface hardness compared to the original sample.

Effects of ultrasonic rolling on the surface integrity of in-situ TiB2/2024Al composite

Yugang Li et al.

Summary: In this study, the in-situ 6 wt% TiB2/2024Al composite was surface-modified by ultrasonic rolling, which significantly improved the surface finish and introduced high-level compressive residual stress and strain hardening, enhancing the comprehensive mechanical properties of the composite. The observed discretization mechanism of TiB2 clusters indicates the feasibility of modifying the distribution of reinforcements, providing a new and cost-effective method for enhancing the surface properties of PRAMCs.

Numerical Simulation and Experimental Validation of Surface Roughness by the Smoothing Small Ball-Burnishing Process

Quoc-Nguyen Banh et al.

Summary: In this study, a simulation procedure is proposed to predict the surface roughness of a burnished workpiece under varying burnishing forces. The roughness of the workpiece surface was approximated by parabolic functions, and the burnishing process was numerically simulated through elastic-plastic indentation and sliding movement. The results were verified through small ball-burnishing experiments on different materials.
