Microstructure and Plastic Instability of (ZrB2
2.1 .Fabrication of in-Situ Composites. In this experiment, the melt reaction method was used to prepare in-situ Al 3 Zr-ZrB 2 /AA6016 particle-reinforced Al matrix composites (PRAMC) with particle fractions of 2 wt.%, 4wt.%, 6wt.%,and 8wt.%. The physical and mechanical properties of the reinforcing phase are shown in Table1.The …
