This work explains about the fabrication of Magnesium reinforced with aluminum, copper, zinc with yttrium metal foam with titanium hydride as foaming agents and calcium stearate as binding agent. The pellets are prepared by powder metallurgy method at a dimension of 20mm diameter and16mm thickness. The sintered samples are tested for mechanical characteristics. The results of mechanical characteristics for the composition Mg-Al-Cu-Re has the highest load bearing capacity of 52.24kN. The composition Mg-Al-Cu-Re has the highest Compressive strength capability of 163.82Mpa. Hardness value with the composition Mg-Al-Re has the highest hardness value of 204.88VHN. Energy absorption for the composition Mg-Al-Cu-Zn-Re has the highest energy absorption characteristics of 186.944KJ because energy absorption is directly proportional to the porosity of the sample. This work explains about the fabrication of Magnesium as parent metal reinforced with aluminum, copper, zinc with yttrium metal foam with titanium hydride as foaming agents and calcium stearate as binding agent. The pellets are prepared by powder metallurgy method at a dimension of 20mm diameter and 16mm thickness. The sintered samples are tested for their mechanical characteristics by compression and hardness tests. The results of mechanical characteristics for load vs displacement with the composition Mg-Al-Cu-Re has the highest load bearing capacity of 52.24kN. Stress vs strain the composition Mg-Al-Cu-Re has the highest stress bearing capability of 163.82Mpa. Hardness value with the composition Mg-Al-Re has the highest hardness value of 204.88VHN.
