Abstract ：
The Ti-based amorphous alloy system was designed based on the principles of "near mixing enthalpy" and "effective atomic size difference," leading to a series of compositions formulated as Ti(76-2x)Mn(7 + x)Cu(17+x) (x = 0, 5, 10, 15). Among these, the Ti56Mn17Cu27 composition exhibited the highest degree of amorphization after 60 h of mechanical alloying. Accordingly, this study systematically investigated the influence of TiC powder addition on the glass-forming ability, microstructure, and thermal stability of Ti56Mn17Cu27 alloy powders. The results revealed that in the absence of TiC, residual crystalline phases, mainly Mn solid solution, remained throughout the mechanical alloying process. In contrast, the addition of TiC significantly accelerated the disappearance of residual Mn diffraction peaks, facilitating the formation of Ti-Mn-Cu/TiC amorphous composite powders after 60 h of milling. The incorporation of TiC promoted dislocation multiplication within and around the residual crystalline regions, disrupted local lattice ordering, and enhanced non-equilibrium atomic diffusion, collectively promoting the amorphization process. Furthermore, TiC addition contributed to particle size refinement and improved uniformity in size distribution. Among all studied compositions, the Ti56Mn17Cu27 + 10 wt.% TiC powder demonstrated the highest amorphous phase fraction, the broadest supercooled liquid region (Delta Tx = 27.09 degrees C), and a relatively low crystallization enthalpy, indicating that the optimal TiC content effectively enhances both amorphous phase formation and thermal stability.

Abstract ：
Rotary tillage blades, as critical components of soil tillage machinery, encounter significant challenges in mountainous agricultural operations, where excessive wear and high energy consumption are persistent issues. To address these problems, this study proposes an integrated strategy combining structural optimization with surface reinforcement. A blade-soil interaction model based on Smoothed Particle Hydrodynamics (SPH) was developed to optimize blade geometry, reducing power consumption to 0.106 kW with a simulation error of only 2.83%. In parallel, Fe60-WC composite coatings containing 30%, 35%, and 40% WC were fabricated on 65Mn substrates using laser cladding. Microstructural analysis revealed significant grain refinement with increasing WC content, while tribological tests showed that the 35% WC coating blades exhibited superior wear resistance, with a mass loss of 1.9 mg, and a relatively low friction coefficient of 0.362. Field trials further confirmed that the blades resulted in a 45.75% reduction in average wear, after structural enhancement and the application of the optimized coating, with a measured loss of 2.259 g compared to the uncoated blades. These findings demonstrate the synergistic benefits of structural optimization and advanced surface engineering, providing an effective pathway to improve the durability and efficiency of rotary tillage blades in demanding field conditions.

Abstract ：
Orah mandarin (Citrus reticulata cv. Orah) lacks systematic grading treatment after harvesting, resulting in a high fresh fruit loss rate and affecting the economic value. There are many drawbacks to traditional manual and mechanical sorting. Therefore, intelligent, rapid, non-destructive surface defect detection technology is significant. In addition to the fruit size, surface defects (e.g., canker, sunburn) are another important criterion for grading fruit. To overcome the challenges in detecting surface defects of orah mandarin, like multi-scale features, significant size differences, and slow convergence speed, we propose the YOLOv8-Orah detection model based on YOLOv8n. Path Aggregation Network (PANet) is replaced by a Focusing Diffusion Pyramid Network (FDPN), and the Diffusion and Spatial Interaction (DASI) module is introduced to effectively fuse and enhance features of different scales and improve detection accuracy. The Bottleneck in the C2f module is replaced by the Hybrid Dilated Residual Attention Block (HDRAB) module to reduce missed detections and false detections. We also introduce the NWD-CIoU joint bounding box loss to accelerate the convergence speed and improve the detection accuracy of small defects. The experimental results show that the improved YOLOv8-Orah model performs well in terms of precision, recall, and average precision, reaching 81.9%, 78.8%, and 84.2%, respectively. Compared with the original YOLOv8n, the improved model increased by 4.0%, 1.7%, and 3.0%, respectively. Meanwhile, the parameter count decreased by 7.76%. Compared with other mainstream models, YOLOv8-Orah achieves a good balance between detection accuracy and computational efficiency. The results technically support defect detection in postharvest orah mandarin and real-time grading of their quality. Meanwhile, it can promote the intelligent development of the bergamot industry.

Abstract ：
Featured Application This study is primarily oriented towards the industrialized Orah sorting process.Abstract This study proposes a grading algorithm for Orah sorting lines based on machine vision and deep learning. The original ShuffleNet V2 network was modified by replacing the ReLU activation function with the Mish activation function to alleviate the neuron death problem. The ECA attention module was incorporated to enhance the extraction of Orah appearance features, and transfer learning was applied to improve model performance. As a result, the ShuffleNet_wogan model was developed. Based on the operational principles of the sorting line, a time-sequential grading algorithm was designed to improve grading accuracy, along with a multi-sampling diameter algorithm for simultaneous Orah diameter measurement. Experimental results show that the ShuffleNet_wogan model achieved an accuracy of 91.12%, a 3.92% improvement compared to the original ShuffleNet V2 network. The average prediction time for processing 10 input images was 51.44 ms. The sorting line achieved a grading speed of 10 Orahs per second, with an appearance grading accuracy of 92.5% and a diameter measurement compliance rate of 98.3%. The proposed algorithm is characterized by high speed and accuracy, enabling efficient Orah sorting.
