“…Because competitive aerobics competition is carried out within a certain period of time required by rules, it has a fairly high demand for athletes' strength and endurance. So in strength training, we must pay attention to strength endurance, especially speed, strength, and endurance training [2]. Therefore, the competitive aerobics athlete special strength training is analyzed and discussed in this paper.…”

The traditional training system based on case teaching is according to the analysis of past competitions and training cases to carry out the strength training of aerobics special movements. The training results cannot be evaluated intelligently and accurately, and the performance of dynamic analysis is poor. To address this problem, the core training system of strength quality of aerobics special movements based on artificial intelligence is designed to realize the intelligent training of the strength quality of aerobics special movements. Through the study of fuzzy paradigm system, intelligent functions such as optimization and decision-making of intelligent fuzzy network are realized. The design system architecture framework includes the modules of sensor, receiver, database, and analysis decision. The core chip of the system is the main control module of Atmega1280 MCU for manmachine interaction, so as to realize the comprehensive training of the strength quality of aerobics special movements. Information collection module is used to collect information on strength training information such as instrument, movement, and language. The problem of phase distortion in signal transmission process is processed by FIR filter. Through information management module, trainee information management and training results statistics and queries are implemented. In the system software part, the system software structure diagram and system startup and landing procedure are given. By analyzing the working process of the module, the strength of aerobics special movements is analyzed. Experimental results show that the designed system can achieve real-time and stable strength training for aerobics special movements and improve training efficiency.

The Ti3AlC2-, (Ti,Nb)3AlC2-and Ti2AlC-based materials turned out to be more resistant than Crofer JDA steel in oxidizing atmosphere as 1000 h long tests at 600• C have shown. But the amounts of oxygen absorbed by the materials during testing were different. The Ti2AlC-based material demonstrated the lowest oxygen uptake, (Ti,Nb)3AlC2-based absorbed a somewhat higher amount and the highest amount was absorbed by Ti3AlC2-based material. Scanning electron microscopy and the Auger study witnessed that amounts of oxygen in the MAX phases before the exposure in air were as well different: the approximate stoichiometries of the matrix phases of materials were Ti3.1−3.2AlC2−2.2, Ti1.9−4Nb0.06−0.1AlC1.6−2.2O0.1−1.2 and Ti2.3−3.6AlC1−1.9O0.2−0.6, respectively. The higher amount of oxygen present in the MAX phase structures may be the reason for higher resistance to oxidation during long-term heating in air at elevated temperature. The studied materials demonstrated high stabilities in hydrogen atmosphere as well. The bending strength of the Ti3AlC2-and (Ti,Nb)3AlC2-based materials after keeping at 600• C in air and hydrogen increased by 10-15%, but the highest absolute value of bending strength before and after being kept in air and hydrogen demonstrated the Ti2AlC-based material (about 590 MPa).

“…2,3 As a fascinating member, Ti 2 AlC is of particular interest since the compound has the lowest density 4 and the best oxidation resistance in the family of MAX phases. [5][6][7] Besides, excellent mechanical and physical properties including the high Young's modulus, 8 self-lubricating, 9,10 good thermal and electrical conductivity [11][12][13] make the Ti 2 AlC ceramic an ideal candidate material for many structural and functional applications, especially in the nuclear energy and sliding electrical area. 9,10,14 To promote practical applications, researches on structural stability of the Ti 2 AlC ceramic in various environment are significant.…”

In this study, the substitution behavior of Ag atoms in the Ti2AlC ceramic was investigated using high‐angle annular dark field scanning transmission electron microscopy (HAADF‐STEM). The TEM sample of the Ag/Ti2AlC interaction area was prepared following the wetting experiment, which was carried out at 1030°C for 5 minute using the sessile drop method. The Ag “single atoms” or “nanoclusters” were found in the crystal lattice of Ti2AlC substrate. The characterizations along two typical crystallographic orientations suggest that both the Ti and Al atoms could be substituted by Ag atoms during the wetting process. In addition, the substitution behavior would contribute to the lattice expansion, which was coordinated by elastic distortion in the Ag nanoclusters with small size. However, when the Ag nanoclusters exceeded the critical size, the intact Ti2AlC structure could no more sustain and defects like stacking faults formed, based on which the Ag nanotwins or polycrystals nucleated.
