Abstract

Objective. The aim of the study is to establish the possibility of recognizing the characteristics of the internal state and confirm the influence of atomic or molecular bonds on the change of certain indicators of physical and mechanical properties of non-magnetic metallic (aluminum, copper) and non-metallic (polymeric) materials. Methods. The research is carried out on the basis of magnetic resonance using neodymium magnets and electric current modulated by white noise signal, as well as with the help of two neodymium magnets. Results. When using neodymium magnets and electric current modulated by a white noise signal in the range of 15-20000 Hz to create the effect of magnetic resonance for non-magnetic metallic materials, an increase in strength is observed until peak values are reached with a gradual decrease to the average value. The interaction of magnetic fields of neodymium magnet and electric current occurs in the body of samples at subcrystalline and subatomic levels. Therefore, this effect is explained by the fact that as a result of vibrations in the material there is a compaction of dislocations. At the moment of change of rest friction to sliding friction, the dislocation accumulation barrier is destroyed, after which the process is repeated again. When two neodymium magnets are used to create the effect of magnetic resonance for textolite and Plexiglas, i.e. for a group of non-metallic materials, the theory of a simultaneous decrease in entropy in the form of an increase in orderliness, namely the orderliness of domains and compaction of dislocations, with an increase in strength is confirmed. The influence of magnetic resonance treatment on changes occurring at the atomic and molecular level in polymeric materials is confirmed. Scientific novelty. The established dependences indicate a connection between the strengthening of the material and the improvement of the quality of its structure: ordering of domains and compaction of dislocations created by magnetic resonance. Practical significance. The obtained data give grounds for the development of a complex method of influence on a number of parameters of physical and mechanical properties using magnetic resonance based on neodymium magnets for influence and the possibility of predicting the life cycle.

对材料的性能进行管理,以优化产品的生命周期
目标。本研究的目的是建立识别内部状态特征的可能性,并确认原子或分子键对非磁性金属(铝、铜)和非金属(聚合物)材料的某些物理机械性能指标变化的影响。方法。本研究是在利用钕磁铁和白噪声信号调制电流的磁共振基础上,以及借助两块钕磁铁进行的。结果。当使用钕磁铁和由15- 20000hz范围内的白噪声信号调制的电流对非磁性金属材料产生磁共振效应时,可以观察到强度的增加,直到达到峰值,然后逐渐降低到平均值。钕磁体磁场与电流的相互作用发生在样品体内的亚晶和亚原子水平上。因此,这种效应可以用这样一个事实来解释:由于材料中的振动,位错会被压实。在静止摩擦转变为滑动摩擦的瞬间,位错积累屏障被破坏,之后该过程再次重复。当使用两块钕磁铁对textolite和plexglass(即对一组非金属材料)产生磁共振效应时,以有序性增加的形式同时减少熵的理论,即域的有序性和位错的压实性,随着强度的增加得到了证实。磁共振处理对高分子材料在原子和分子水平上发生的变化的影响得到证实。科学的新奇。已建立的依赖关系表明,材料的强化与其结构质量的改善之间存在联系:磁畴的有序和由磁共振产生的位错的压实。现实意义。所获得的数据为开发一种复杂的影响方法提供了依据,该方法利用基于钕磁铁的磁共振来影响物理和机械性能的一些参数,并有可能预测寿命周期。
