MB15合金系含Zr的镁合金,其强度高,比重小,工艺性能良好,在航空及原子能工业中广泛应用。 MB15合金中加入Zr能细化晶粒,提高再结晶温度,因而使合金强度和综合性能明显提高。高熔点难熔金属Zr的加入,铸造时易在铸锭中形成化合物偏析,降低制品性能。六十年代,我厂试制MB15合金时,在铸锭上出现大量化合物偏析聚集物,研究结果认为化合物是MgZn和少量α(Zr),七十
MB15 alloy containing Zr-based magnesium alloy, high strength, small proportion, good process performance, widely used in aviation and atomic energy industry. Addition of Zr into MB15 alloy can refine the grains and increase the recrystallization temperature, so the strength and overall performance of the alloy are obviously improved. Refractory refractory metal Zr addition, easy casting in the formation of compounds segregation, reducing product performance. Sixties, MB15 alloy factory trial, a large number of compounds in the ingot segregation of aggregates, the results of the study that the compound is a small amount of MgZn and α (Zr), seventy
