Based on the introdu tion to the two kinds of new technology,liquid metal forging and liquid metal extrusion.the results have been given out that the properties of ZA27 alloy are enormously improved by the processes,and the strengthening mechanism has been analyzed in the paper,For the liquid metal forging process, it is because the liquid metal is crystallized under the high pres ure,which leads to a multiple effect including the densification of materials,and solution and precipitation strengthening.For t...
