The joint effect of samarium and holmium on the properties of an IMV7-1 Mg–Y–Gd–Zr alloy in two different states, namely, homogenized and homogenized and subsequently aged at 200°C to the peak strength, has been studied at testing temperatures of 20 and 250°C. Samarium and holmium do not change the behavior of the Mg–Y–Gd–Zr alloys during aging; at the same time, the presence of ~4% Sm in the alloys accelerates the decomposition of the magnesium solid solution and increases their strength properties, and the presence of 2 to 5% Ho in the IMB7-1 alloys containing 4% Sm leads to a decrease in their strength properties.

Hol和on联合作用对Mg-Y-Gd-Zr合金强度性能的影响

在测试中，研究了of和对IMV7-1 Mg-Y-Gd-Zr合金在两种不同状态（均质和均质并随后在200°C时效至峰值强度）的性能的共同影响。温度为20和250°C。aging和在时效过程中不会改变Mg-Y-Gd-Zr合金的行为。同时，合金中〜4％Sm的存在会加速镁固溶体的分解并提高其强度性能，而含有4％Sm的IMB7-1合金中存在2％至5％Ho会导致强度特性下降。
