Mg _69−x Zn ₂₇ Ca ₄ Y _x (x=0， 1， 2 at.%) 合金通过 X 光检查衍射，压缩测试，电气化学的处理，和沉浸测试被调查。Mg ₆₉ Zn ₂₇ Ca ₄ 合金被发现绝对非结晶，并且它的形成眼镜的能力与 Y 的增加减少了。Mg ₆₈ Zn ₂₇ Ca ₄ 展出的 Y ₁ 合金一超离频在象为超过 3.1% 的塑料紧张的高能力一样的 1010MPa 上面的压缩力量。电气化学并且沉浸测试表明这些做 Y 的 Mg–Zn–Ca 合金在 37 °C 在模仿的身体液体(SBF ) 有好简历腐蚀抵抗。cytotoxicity 测试的结果为这些合金显示出高房间生存能力，它意味着好简历相容性。

英文摘要：

The micro-alloying effects of Y on the microstructure, mechanical properties, and bio-corrosion behavior of Mg69-xZn27Ca4Yx（x= 0, 1, 2 at.%） alloys were investigated through X-ray diffraction, compressive tests,electrochemical treatments, and immersion tests. The Mg69Zn27Ca4 alloy was found to be absolutely amorphous, and its glass-forming ability decreased with the addition of Y. The Mg68Zn27Ca4Y1 alloy exhibited an ultrahigh compressive strength above 1010 MPa as well as high capacity for plastic strain above 3.1%.Electrochemical and immersion tests revealed that these Y-doped MgeZ neC a alloys had good bio-corrosion resistance in simulated body fluid（SBF） at 37℃. The results of the cytotoxicity test showed high cell viabilities for these alloys, which means good bio-compatibility.
