日本东北大学科学家近日开发成功具有极高强度和延展性的镁合金,可为航空航天、通信和机械等工业提供优质材料。 新的镁合金是采用急速凝固法制成的,具有100至200纳米的微细结构。按原子量计算,它的成分97%是镁,钇和锌分别占2%和1%。这种新型镁
Japan’s Tohoku University scientists recently developed a very high strength and ductility of magnesium alloy, for the aerospace, communications and machinery industries to provide high-quality materials. The new magnesium alloy is made by rapid solidification and has a fine structure of 100 to 200 nanometers. In terms of atomic weight, 97% of its composition is magnesium, with yttrium and zinc accounting for 2% and 1%, respectively. This new type of magnesium
