Microstructure and Mechanical Properties of AZ31 Mg Alloy Foams |
| 초록 |
Melt foaming method is one of cost-effective methods to make metal foam and it has been successfully applied to fabricate Al foam and Al alloy foams. Mean while, some researchers have reported that Mg alloy foams prepared by melt foaming method using titanium hydride as blowing agent have extraordinary coarse pore structures.It is difficult to control the pore size and distribution of Mg alloy foam by melt foaming method using titanium hydride as blowing agent and extraordinary coarse pore structures is often found in the Mg alloy foams. Using CaCO3 instead of titanium hydride as blowing agent, AZ31 Mg alloy foams with small well structure, porosity 68.5~71.2 % and average pore size 0.04~0.05 cm could successfully be fabricated In this study; AZ31 Mg alloy foam with the holding time of 120s had the best energy absorption. The energy absorption value of AZ31Mg foam was 5.52MJ/M3. After that, AZ31 foams sample was polished and rusted. The thickness cells were analyzed by use of Metallurgical Microscope and software. Then SEM micrograph of AZ31 Mg alloy foam and EDS analysis of the cell wall. |
