WebApr 19, 2024 · When the scanning speed is too low, it is easy to make the local liquid phase too much, resulting in nodules and decreased relative density [17,18]. Concurrently, when V is too small, due to the strong Marangoni effect, defects such as spheroidisation and pores are easily formed in the molten pool, so the overall relative density value is not high.
