Description
technical field [0001] The invention relates to an alloy standard sample and a preparation method thereof, in particular to an aluminum-scandium alloy spectral standard sample. Background technique [0002] The 5A70 and 5A71 series aluminum alloys are new alloys developed and registered by Southwest Aluminum (Group) Co., Ltd. in recent years, which belong to a series of aluminum scandium alloys (Al-Mg-Sc). After the alloy is alloyed with a trace amount of scandium (0.07%-0.35%), compared with similar alloys without scandium, the aluminum-scandium alloy has high strength, good plastic toughness, excellent corrosion resistance and welding performance, and is the next generation aluminum-lithium alloy. A new generation of lightweight structural materials for aerospace, aviation, and ships. 5A70 / 5A71 series aluminum alloys contain Mg, Mn, Zr, Ti, Sc, Zn, Ni, Cu, Fe, Si, B, Be, Cr13 elements. [0003] As we all know, the development of new alloys is inseparable from the analysi...
