The mechanical coupling effect of laser shock and shot peening in Ti–6Al–4V dovetail joint: Residual stress, microstructure and fretting fatigue behavior by Chen Wang, Xiong Zhang, Yan Yin, Weifeng He, Yibo Shang, Liucheng Zhou

“…Fretting fatigue tests reveal load dependent improvements: at higher loads (10 kN, 12 kN), LSP + SP yields the greatest life extension (7.08 and 4.57 times), while at lower loads (8 kN), SP offers the highest enhancement (8.71 times). Microstructural analysis indicates that LSP + SP transforms multi-crack initiation into single-source fracture and deepens crack origins from 70 μm to 663 μm, consistent with the refinement zone. …”

Effects of Cu and Mg alloying and low-temperature aging on microstructure characteristics and mechanical properties of heat treatment-free cast Al–Si–Cu–Mg alloys by Xinxin Ma, Yanpeng Pan, Liwen Chen, Hua Hou, Jibo Hou, Yuhong Zhao

“…The results indicate that the as-cast Al–Si–Cu–Mg alloys exhibit multiple intermetallic phases, with their formation kinetics strongly dependent on both Cu/Mg ratios and elemental concentrations. Meanwhile, microstructural observations of T5-age alloys showed that different casting processes affect the morphology and distribution of the nano-precipitates, consequently governing the strength and plasticity of the alloys.Specifically, the Al–10Si–1Cu-0.6 Mg alloy (Cu/Mg = 1.7) demonstrated an optimal combination of strength and ductility, attributed to the refined size and content of its precipitates.…”

Effects of Different Y₂O₃ Contents on the Microstructure of Ni-Based WC Ceramic Composite Coating by Laser Cladding by JIN Lijun, LIU Zhenzhen

“…To study the effect of different rare earth Y2O3 contents on the microstructure of laser-cladded Ni-based WC ceramic composite coatings， the Ni-based WC ceramic composite coatings were melted on the surface of 9SiCr using 900W YAG solid laser.The effects of Y2O3 on the structure of the composite coatings were systematically investigated by means of scanning electron microscope (SEM) and X-ray diffraction(XRD).Results showed that the addition of Y2O3 could cause alterations in the relative phase composition ratios within the coating，and Y elements were mainly concentrated at the grain boundary edges.Adding a suitable amount of Y2O3 effectively reduced the coating defects during the cladding process， improved coating densification， promoted more homogeneous microstructural distribution， and significantly refined grain size.When the amount of Y2O3 was 1.5%， the microstructure uniformity of the as-prepared coating was the highest.…”
