Powder-bed metal additive manufacturing frequently suffers from high porosity issues arising from gas entrapment and keyhole instability. This study presents, for the first time, a breakthrough methodology: in-situ molten pool modulation via low-pulse-energy coaxial laser shock. By coupling an addit…
With growing interest in Laser Additive Manufacturing (LAM) of High-entropy alloys (HEAs) during most recent years, the design of compositional elements and process strategies are primary methods to overcome undesirable microstructures and defects. Here we propose a new approach, a novel real-time L…
In the field of electronic packaging, lead-free solders are primarily binary or ternary Sn-based eutectic or near-eutectic alloys, with the Sn-rich phase constituting the matrix phase. To characterize the mechanical properties and stress-strain relationship of the Sn-rich phase, nanoindentation test…
In recent years, digital twins have attracted extensive attention and are becoming increasingly complex. Current digital twin implementations are predominantly confined to specific scenarios, and there remains a lack of methods for constructing complex digital twins in the face of multi-level and mu…
‘The spectral leakage (SL) from windowing and the picket fence effect (PEF) from discretization’ have been among the standard contents in textbooks for many decades. The SL and PEF would cause the distortions in amplitude, frequency, and phase of signals, which have always been of concern, and attem…
