A7N01P-T4 aluminum alloy plates for high-speed trains will experience a certain amount of fatigue damage under alternating loads. Three groups samples, P0 (no damage), P1 (loading stress 30 MPa), and P2 70 were created, corrosion crack growth (CFCG) tests conducted in 3.5 wt.% NaC1 solution. The rate was found to increase after as the degree increased. In addition, base metal exhibited obvious secondary cracks bifurcations damage. It is believed that causes concentration material, while...
EA4T steel has been widely used in the manufacture of railway axles. Laser cladding remanufacturing technology to repair axles, and failure behaviors axles studied. In this work, a class original FeCrNiMo alloy layers that contain rare-earth elements was successfully fabricated through laser technique on substrates. The microstructure elemental distribution were analyzed scanning electron microscopy (SEM), transmission (TEM) probe microanalysis (EPMA). Simultaneously, microhardness, bond...
In this paper, a fault-tolerant velocity estimation method is proposed for quadrotors in GPS denied environment. A novel filter developed light of the quadrotor model and measurements from optical flow inertial sensors. The capable detecting isolating sensor faults, by which accuracy stability will be improved. It also demonstrated that wind observable filter. Therefore, new can implemented windy environment, significant improvement to previous model-aided estimator. At end, some simulations...
In this study, laser cladding on EA4T steel was carried out. The Composition of HAZ the analyzed by OM and SEM. effect microstructural transformation discussed. distribution alloying elements micromechanical properties interface were tested. results show that microstructures heat-affected zone are mainly lath martensite. homogenization austenite dissolution carbides near not sufficiently developed, coarse grains observed. fine-grained area HAZ, microstructure is composed martensite a small...
The Ni–Cr–Fe metal powder was deposited on EA4T steel by laser cladding technology. microstructure and chemical composition of the layer were analyzed optical microscopy (OM), scanning electron (SEM) X-ray diffraction (XRD). bonding ability between matrix measured. results showed that metallurgical bonding. composed planar crystals, columnar crystals dendrite, which consisted Cr 2 Ni 3 , [Formula: see text] phase, M[Formula: text]C 6 B phases. When feeding speed reached 4 g/min, upper...
