To the best of our knowledge, the general approach of designing alloys with specified mechanical properties does not exist. This is due to the unresolved problem of analysing the set of heterogeneous variables that affect the mechanical properties along its production line from the smelting of the alloy to the manufacture of the final product. Here, we show that in principle this problem can be solved by analysing all the strengthening mechanisms in a common reference frame with reference to the single factor namely, the generalized degree of metallicity and covalence, which characterizes the entire interatomic bonds in all phases of the alloy. Such factors are able to reflect the results of hardening by various mechanisms because of the correlation with the mechanical properties. From the energy view point, these factors correspond to the proportion of the metallic and covalent bonds energy in the total energy of all chemical bonds in the alloy. Based on the approach being developed, we considered a method for predicting new doping systems for dispersively strengthening aluminum alloys according to the criterion of a given strength and have considered the methodology of optimizing chemical composition in steel smelting which is used for mass production of parts according to the criterion of the desired mechanical properties obtained due to solid solution hardening.

据我们所知,不存在设计具有特定机械性能的合金的一般方法。这是由于尚未解决的问题,即分析影响从合金熔炼到最终产品制造的生产线上的机械性能的一组异质变量。在这里,我们表明,原则上可以通过参考单个因素 (即金属性和共价的广义度) 分析共同参考框架中的所有强化机制来解决此问题,该因素表征了合金所有相中的整个原子间键。由于与机械性能的相关性,这些因素能够反映各种机制的硬化结果。从能量的角度来看,这些因素对应于金属键和共价键能量在合金中所有化学键的总能量中的比例。根据正在开发的方法,我们考虑了一种根据给定强度的标准预测用于分散强化铝合金的新掺杂体系的方法,并考虑了根据要求的标准优化炼钢中的化学成分的方法。由于固溶硬化而获得的机械性能。
