摘要

介绍了四氟化锆对AK7ch铝合金的强化工艺的重要特点。选择含有四氟化锆的复合熔剂是合理的。结果表明,为了从铝熔体中的四氟化锆中回收锆,首先必须确保在强化混合物中形成氟锆酸钠或氟锆酸钾。介绍了从四氟化锆中回收锆的机理。给出了获得AK7ch合金的工艺建议。已经确定,在引入其他合金元素,即硅和镁之前,必须将改性后的合金用复合熔剂注入液态铝中。指出了从复合熔剂向铝熔体中注入锆的最高合适温度。回收的锆的最大含量为0.4%。研究了用四氟化锆增强合金的微观结构和力学性能,四氟化锆以0.8%至1.2%的量注入合金中。用锆对铝合金AK7ch进行变质处理,使硅溶液在铝(α相)中的晶粒得以磨削。未观察到其他结构变化。合金的抗拉强度和相对伸长率分别提高了1.3倍和1.7倍。

TECHNOLOGICAL FEATURES OF MANUFACTURING ALLOY AK7h STRENGTHENED WITH ZIRCONIUM INTRODUCED WITH ZIRCONIUM TETRAFLUORIDE
The paper considers the important features of the technology of strengthening AK7ch aluminum alloy with zirconium introduced with its tetrafluoride. The choice of a complex flux containing zirconium tetrafluoride in its composition is justified. It is indicated that in order to recover zirconium from its tetrafluoride in the aluminum melt, it is first of all necessary to ensure the formation of sodium or potassium fluorozirconate in the strengthening mixture. The mechanism of recovery of zirconium from tetrafluoride is presented. Technological recommendations for obtaining AK7ch alloy are given. It has been established that the complex flux intended to the alloy, which is modified, must be injected into liquid aluminum before the introduction of other alloying elements, namely silicon and magnesium. The maximum appropriate temperature for injecting zirconium into the aluminum melt from the complex flux is indicated. The maximum amount of zirconium that was recovered is 0.4%. The microstructure and mechanical properties of an alloy strengthened by zirconium from its tetrafluoride, which was injected into the alloy in the amount from 0.8 to 1.2%, were studied. As a result of the modification of aluminum alloy AK7ch with zirconium, the grains of silicon solution in aluminum (α-phase) are grind. No other structural changes are observed. The value of tensile strength and relative elongation of the alloy increases by 1.3 and 1.7 times, respectively.
