摘要: <正> 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
Abstract:A new high strength Mg sheet alloy, Mg-(3.0—3.8)%Zn-(0.6—1.0)%Y-(0.4—0.7)%Zr, has been developed. The final heat treatment condition is T_8 condition, namely, 515—520℃ solution treated 1h, water quenched+15% cold work+200℃ 24h. Its room temperature tensile properties are shown as: σ_b=33.5—34.0 or 29.0—30.0 kgf/mm~2; σ_(0.2)=30.0—30.5 or 19.5—20kgf/mm~2; δ=12—14 or 13.5—22.0% in longitudinal or transverse direction respectively. And its tensile properties below 250℃ are superior to that of both HM21XA-T_8 and AZ31B-H_(24).
