Abstract

Grain-oriented silicon steel is used in transformer applications, but the processing of steel sheet induces the deterioration of magnetic properties. The water jet guided laser (WJGL) method is applied to process grain-oriented Fe-3 wt.% Si steel, and its influence on the magnetic properties is compared with shear cutting (SC) and nanosecond laser processing (CL). SC induces local orientation change and large residual stress, and CL results in a dual-layer heat-affected zone. Samples processed by WJGL exhibit smaller heat-affected zone and lower thermal stress, thus ensuring better magnetic performance. The highest magnetic induction of 1.86 T and the lowest iron loss of 0.87 W kg⁻¹ (P_17/50) are obtained at a laser power of 5W and a speed of 1 mm/s. Obtained results reveal the potential of WJGL method for manufacture of steel sheet, and the balance between processing efficiency and magnetic properties could be achieved through adjusting the processing parameters.

水射流激光加工增强晶粒取向fe - 3wt .% Si钢板的磁性能

晶粒取向硅钢用于变压器，但钢板的加工会导致磁性能的恶化。采用水射流制导激光（WJGL）方法加工晶粒取向的fe - 3wt .% Si钢，比较了水射流制导激光（WJGL）方法与剪切切割（SC）和纳秒激光加工（CL）方法对其磁性能的影响。SC引起局部取向变化和较大残余应力，CL导致双层热影响区。WJGL处理后的样品具有更小的热影响区和更低的热应力，从而保证了更好的磁性能。当激光功率为5W，速度为1mm /s时，磁感应强度最高为1.86 T，铁损耗最低为0.87 W kg−1 （P17/50）。研究结果揭示了WJGL法在钢板加工中的潜力，通过调整加工参数可以实现加工效率与磁性能之间的平衡。

期刊介绍： Vacuum is an international rapid publications journal with a focus on short communication. All papers are peer-reviewed, with the review process for short communication geared towards very fast turnaround times. The journal also published full research papers, thematic issues and selected papers from leading conferences. A report in Vacuum should represent a major advance in an area that involves a controlled environment at pressures of one atmosphere or below. The scope of the journal includes: 1. Vacuum; original developments in vacuum pumping and instrumentation, vacuum measurement, vacuum gas dynamics, gas-surface interactions, surface treatment for UHV applications and low outgassing, vacuum melting, sintering, and vacuum metrology. Technology and solutions for large-scale facilities (e.g., particle accelerators and fusion devices). New instrumentation ( e.g., detectors and electron microscopes). 2. Plasma science; advances in PVD, CVD, plasma-assisted CVD, ion sources, deposition processes and analysis. 3. Surface science; surface engineering, surface chemistry, surface analysis, crystal growth, ion-surface interactions and etching, nanometer-scale processing, surface modification. 4. Materials science; novel functional or structural materials. Metals, ceramics, and polymers. Experiments, simulations, and modelling for understanding structure-property relationships. Thin films and coatings. Nanostructures and ion implantation.
