“…In his work, Gonçalves et al studied the ferroelectric domain structure of (Pb.La. )TiO transparent ceramics and its response to an external electric feld through piezoelectric response force microscopy (PFM) [6]. By responding to the ferroelectric domain structure and its applied electric feld, we can have a better understanding of its feld.…”

With the development of national railways and railways as one of the important channels for heavy-haul transportation, the construction of heavy-haul railways must be a rapid development, which makes it inevitable that the heavy-duty situation of small-distance interchange tunnels will appear. Nanomaterials refer to materials that have at least one dimension in the three-dimensional space in the nanoscale range (1 nm∼100 nm) or are composed of them as basic units. Ferroelectric domain polarization refers to the existence of electric domains in ferroelectrics, electric domains refer to small regions with the same spontaneous polarization direction, and the boundaries between electric domains and electric domains are called domain walls. It is also urgent to study the dynamic structure of the surrounding rocks of heavy-duty railways. This article aims to study the use of nanomaterial and ferroelectric domain technology to improve the overall strength, wear resistance, toughness, and other properties of steel to ensure the safety of the surrounding rock dynamic structure of the heavy-duty railway in the small clearance intersecting tunnel. Moreover, on this basis, this article proposes the method of spraying steel with nanomaterials and the use of ferroelectric domain polarization technology. The strength and wear resistance of steel can be improved under different nanomaterial content and the degree of ferroelectric domain polarization. Sustainability and toughness have been improved, respectively. After the wear resistance experiment and analysis, the experimental results of this article show that the impact resistance of the steel increased by 18.75%. When 0.012% of CeO2 is added, the impact toughness of the steel is increased to the maximum of 3.4 J, an increase of 16.31%, and a 37% increase in wear resistance. Under the premise of ensuring the demand for heavy-duty transportation, the safety performance and sustainability of transportation are greatly improved.

“…Domain configuration is one of the key factors in determining the preferred orientations in the sample when it is subjected to a poling field. Literature reports suggest that finer domain structure can be attributed to the high density of mobile domain walls, which in turn enhances the overall piezoelectric properties as an extrinsic contribution [48,49]. Alternatively, it is proposed and verified that enhanced piezoelectricity is possible in bigger domain sized samples due to the propensity for intrinsic polarization rotation inside the domains rather than the domain wall contribution [50].…”

Pb-free piezoelectric BaTi1–xSnxO3 system is one of the promising environment friendly ceramics due to its superior piezoresponse properties. The enhanced piezoresponse on this system has a strong correlation to their microscopic and macroscopic characteristics. In this work, the effects of structural and microstructural evolution on the piezoelectric properties of BaTi0.97Sn0.03O3 compound are explored. The structural and piezoelectric analysis elucidates that the samples experiencing the field induced tetragonal to orthorhombic phase transformation exhibits better piezoresponse. In addition, the domain configurations have a strong correlation with the synthesis conditions where the distribution of lamellar and/or stripe types of domain patterns show enhancement in comparison to Labyrinth type with increase in sintering temperature. The Rayleigh analysis confirms that the increase in irreversible nature of non-180° domain walls can improve the d 33 of the BaTi0.97Sn0.03O3 samples. Overall, the results illustrate that the stripe domain configurations and field induced polarization switching from tetragonal to orthorhombic phase favour superior piezoresponse in the sample.
