摘要：

Closed-cell Al-Si alloy foam was produced from two bulk alloy strips. Preform sheet containing titanium hydride (TiH2) particles was first manufactured through accumulative roll-bonding (ARB) processing. Large ARB cycle number was effective to achieve uniform distribution of the TiH2 particles in the Al-Si matrix. Following high temperature foaming tests revealed that high porosity and small pore size can be obtained from the preform prepared through large cycle number. These results indicate that a suitable ARB processing condition enables to optimize the cell microstructure of the metal foams.
