本简报报道室温强度达到σ_b≥32kgf/mm~2,σ_(0.2)≥25kgf/mm~2,δ≥10%的高强度板材镁合金。根据美国的高强度变形板材镁合金的资料表明,已投入生产的合金有AZ31A-H_(24)和ZE 10A-H_(24)。前者相当于苏联的MA_(2-1),含3%Al,1%Zn;后者含1.2%Zn,0.18%RE。此外,还有试验板材合金ZK41XA-H_(26),含4%Zn,0.5%Zr,0.6%RE.AZ31A-H_(24)及ZE10A-H_(24)合金的室温强度极限σ_b≤31.5kgf/mm~2,δ<9%。另外尚有ZK60A,即苏联的BM_(65-1),这一合金一般是作棒材、型材、管材和锻件,作为板材
This bulletin reports the strength of the room temperature σ_b ≥ 32kgf / mm ~ 2, σ_ (0.2) ≥ 25kgf / mm ~ 2, δ ≥ 10% of the high-strength sheet magnesium alloy. According to the data of the high-strength deformed sheet magnesium alloy in the United States, AZ31A-H_ (24) and ZE 10A-H_ (24) have been put into production. The former is equivalent to the Soviet MA_ (2-1), containing 3% Al, 1% Zn; the latter containing 1.2% Zn, 0.18% RE. In addition, the room temperature strength limit σ_b of the test plate alloy ZK41XA-H_ (26) containing 4% Zn, 0.5% Zr and 0.6% RE.AZ31A-H_ (24) and ZE10A-H_ (24) mm ~ 2, δ <9%. There are also ZK60A, the Soviet Union BM_ (65-1), the alloy is generally used as rods, profiles, pipes and forgings, as a plate
