Effects of metal flow on mechanical properties particularly on fatigue strength of ZK60A forgings were studied. The forgings are the most strong in yield, tensile and fatigue strength in the longitudinal direction and weaken as the loading direction turns to the transverse direction. They have particularly the yield strength so weak as 13 to 15 kgf/mm2 that corresponds to only a half of the strength in the longitudinal direction. The maximum elongation is achieved at angles 45° to 60° to the metal flow direction. The fatigue strength σW is expressed as a function of tensile strength σB, σW/σB 0.87-0.07 logN. where N is cycles: ZK60A magnesium forgings have a greater effect of metal flow on strength than aluminum alloy and AZ80A magnesium alloy forgings.
