... testing, fatigue life testing, fractographic analysis and CT analysis, followed by microhardness measurements, providing a detailed assessment of internal defects and their impact on fatigue performance. Findings The fatigue test results showed better fatigue life for samples printed with Y...

... near-surface pores and improving the microhardness of the samples compared to the CB process. Furthermore, the fatigue life of the as-built sample, initially at 66,000 cycles, experienced a slight improvement after CB treatment, reaching 347,000 cycles. However, the UAB process significantly enhanced...

... with a pulse width of 10 ns using laser spot diameter of 3 mm. Post to the LSP treatment, the surface roughness, fatigue life assessment and microstructural evolution analysis is performed. For this, different advanced characterisation techniques are used, such as scanning electron microscopy attached...
