- In this study, Aluminum closed-cell foam was produced through accumulative roll bonding using TiH2 as blowing agent. Then, the effect of the number of rolling passes, foaming temperature, foaming time and heating rate on percent of porosity was investigated. The results indicate that foaming process improves with increasing temperature. The TiH2 powder was uniformly dispersed into the matrix with increasing the number of roll passes and caused an increase of the percent of porosity. Finally, 41% of porosity at foaming temperature of 680°C, foaming time of 5 min and heating rate of 10(°C)/s was produced.
Keywords: "closed-cell foam", "titanium hydride", "temperature of foaming", "time of foaming"
