Influences of in-situ ZrB2 and TiB2 particles on Portevin-Le Chatelier effect for AlSi9Cu1 alloy

In this paper, the plastic instability phenomenon Portevin-Le Chatelier effect (PLC) was investigated in AlSi9Cu1 alloy and the in-situ (ZrB2+TiB2)/AlSi9Cu1 composites fabricated from the Al-K2TiF6-K2ZrF6-KBF4 system. Microstructure observation and X-ray diffraction testing revealed that the ZrB2 an...
