超塑性ZnA15和ZnA14合金是一种以锌为基,加入少量铝、微量镁和稀土的新型超塑材料,是一种能实现高超塑性并得到工业应用的锌基合金。它具有比重大,超塑性性能优良和抗腐蚀性能较好等特点。超塑变形温度(280～350°G)和变形速度范围较宽,在特定条件下,其延伸率可达5000%以上,流变应力为0.2公斤/毫米~2,该合金比重为6.62公斤/厘米~3,抗拉强度31～33公斤/毫米~2,且组织均匀致密,是制造录音机、飞轮最理想的材料。
Superplastic ZnA15 and ZnA14 alloy is a zinc-based, adding a small amount of aluminum, trace magnesium and rare earth new superplastic material is a can achieve superplasticity and industrial application of zinc-based alloys. It has a large proportion of excellent superplastic performance and good corrosion resistance and so on. The superplastic deformation temperature (280 ~ 350 ° G) and deformation speed range is wide, under certain conditions, the elongation rate can reach more than 5000%, the flow stress is 0.2 kg / mm ~ 2, the specific gravity of the alloy is 6.62 kg / Cm ~ 3, the tensile strength of 31 ~ 33 kg / mm ~ 2, and the organization uniform and compact, is the manufacture of tape recorders, flywheels the best material.
