摘要: Abstract AZ91 alloy was subjected to multidirectional forging (MDF) and the relationship between microstructures mechanical properties generated by MDF were investigated. The results showed that after 1 pass grain size of decreased compared with as-cast alloy, amount recrystallization grains increased when temperature from 250 °C 400 °C. With increasing passes at 350 °C, gradually refined. A typical basal texture obtained pass, then pole scattered increase passes. Mg 17 Al 12 phases precipitated along boundaries during MDF, which could hinder growth grains. Both tensile strength elongation failure significantly enhanced till 3
