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 ：
Three-dimensional path planning in emergency logistics is a complex optimization problem, particularly challenging because it requires considering conflicting objectives such as flight time, energy consumption, and obstacle avoidance. Unlike most urban logistics research, this study examines emergency delivery path planning in mountainous environments during natural disasters. One of the most effective approaches to this problem is to employ multi-objective evolutionary algorithms. However, while multi-objective genetic algorithms can handle multiple conflicting objectives, they struggle when dealing with complex constraints. This paper proposes a multi-objective genetic optimization method, Adaptive Crossover-Mutation Multi-Objective Genetic Optimization (ACM-NSGA-II), based on the classic NSGA-II framework. Inspired by the principle of symmetry, this method dynamically adjusts the mutation and crossover rates based on population diversity to maintain a balanced exploration-exploitation trade-off. When population diversity is low, the mutation rate is increased to promote exploration of the solution space; when population diversity is high, the crossover rate is increased to promote better information exchange. The algorithm maintains symmetry by gradually adjusting the step size, balancing adaptability and stability. To address the obstacle avoidance problem, we introduced a dynamic path repair strategy that respects the symmetry of no-fly zone boundaries and terrain features, ensuring the safety and efficiency of Unmanned Aerial Vehicles. This algorithm jointly optimizes three objectives: safety cost, flight time, and energy consumption. The algorithm was tested in a mountainous environment model simulating a remote area. In experiments, ACM-NSGA-II was compared with several mainstream evolutionary algorithms. The Pareto set and hypervolume metrics of each method were recorded and statistically analyzed at a 5% significance level. The results show that ACM-NSGA-II outperforms the baseline algorithms in terms of diversity, convergence, and feasibility. Specifically, compared with the traditional NSGA-II, ACM-NSGA-II improved the average hypervolume metric by 53.39% and reduced the average flight time by 24.26%. ACM-NSGA-II also demonstrated significant advantages over other popular standard algorithms. Experimental results show that it can effectively solve the path planning challenge of emergency logistics Unmanned Aerial Vehicles in mountainous environments.

Abstract ：
The study investigated the influence of hot extrusion on the microstructure, mechanical properties, and corrosion resistance of powder metallurgy titanium alloys with different Cu contents (x=1,5,10 %). The microstructure of these alloys predominantly consists of coarse layered alpha and (3 phases. A higher Cu content leads to the formation of a coarse blocky Ti2Cu phase, exhibiting dimensions in the range of hundreds of microns, along with an increased volume fraction of both the (3 and Ti2Cu phases. After hot extrusion, the microstructure undergoes significant refinement, transitioning from a coarse layered structure to nano-equiaxed grains at a Cu content of 1 %. However, this grain refinement effect diminishes at a Cu content of 5 %, where the equiaxed grains increase to about 1 mu m, and the size of the Ti2Cu phase is reduced to the nanometer scale. Further increases in the Cu content result in a mixed microstructure comprising ultrafine layers and equiaxed grains. The mechanical properties of compression tests are enhanced, achieving a yield strength of about 1500 MPa. The strength increases by approximately 380 MPa with the 1 % Cu content, attributed to grain boundary strengthening. At 5 % Cu content the strength rises by about 290 MPa, with contributions of 136 MPa from grain boundary strengthening, 60 MPa from precipitation strengthening, and the remainder from solid solution strengthening. The mechanisms of strengthening remain consistent with further increases in Cu content. The extruded Ti6Al4VxCu alloys with 5% Cu content exhibit the most favorable corrosion performance. The sizes of the grains, as well as the proportion and dimensions of precipitated phases, play a critical role in the formation of the passive film and affect galvanic corrosion, thereby impacting overall corrosion performance.

Abstract ：
Aiming to address the wear and replacement inconvenience of concrete mixer liners, this study utilizes a laser cladding system to clad Fe60 alloy powder on the liner. It investigates the influence of different process parameters on the forming quality of the Fe60 alloy powder cladding layer. The optimal process parameters were obtained by weighted comprehensive evaluation, and single-layer multi-pass cladding experiments were carried out under the optimal process parameters to investigate the effects of a 30%, 40%, and 50% lap rate on the surface flatness and forming quality of the cladding layer. Using a metallographic microscope, a scanning electron microscope analysis of the macro morphology and microstructure of the cladding layer was conducted, a DPT-5 penetration flaw detector was used to observe the cracks on the surface of the multi-channel cladding, a microhardness tester and friction and wear experimental machine were used for the hardness of the cladding layer, and an abrasive wear resistance test was conducted. The results show that under the process parameters of a laser power of 900 W, powder feeding speed of 7 g/min, scanning speed of 600 mm/min, and 50% lap rate, the average microhardness of the fused cladding layer reaches 742 HV, which is 1.8 times higher than that of the liner plate, and the coefficient of friction is 0.57, which improves the liner plate's wear resistance performance and service life.
