| 英文摘要 | pyramid-like spikes in a single crystal superalloy were investigated upon irradiation with picosecond (ps) laser pulses (200 ps, 800 nm, 1 khz) under different laser fluences and pulse numbers. both sides and grooves of pyramid-like spikes were covered with ripples, which had a period of similar to 760 nm. the pyramid-like spike separation increased obviously with increasing laser fluence. microstructural investigations indicate that the pyramid-like spikes were initiated with subsequent pulses from a smooth surface with corrugations and ripples. the coexistence of capillary waves for spikes and capillary waves for ripples in the melted material can be used to explain the formation of the pyramid-like spikes. |
