摘要：
In a 15 vol.% Al2O3 particle-reinforced 6061 Al alloy the interfaces particle/matrix were investigated by analytical transmission electron microscopy. The aim was to find possible reaction products in the as-cast state and after solution heat treatment followed by precipitation hardening. To clarify the influence of the solution heat treatment the temperature and the duration of the solution heat treatment were varied. In the as-cast state there were no reaction products on the interfaces particle/matrix. After solution heat treatment in the range between 525-degrees-C and 560-degrees-C, MgAl2O4 (spinel) could be found at the interfaces by electron diffraction. After extended time and at higher temperature nearly closed layers of spinel around the Al2O3 particles were observed.
