Complex formation structures lead to significant differences in the failure mechanisms of hobs. WC-reinforced medium entropy composite coatings exhibit excellent comprehensive properties. However, wear mechanism different is still unclear. In this study, FeNiCr-WCx (x = 0, 40, 50, 60 wt%) were prepared on surface H13 steel using laser cladding technology. The friction and FeNiCr-WC under pair conditions was discussed. results show that mainly consist reinforced phase, lamellar eutectic...
FeCoCrNi and FeCoNiCrMo0.2 high-entropy alloy powders were prepared by gas atomization. Two kinds of coatings on the surface 304 stainless steel laser cladding technology. The effect Mo element microstructure coating its corrosion behavior in 3.5 wt.% NaCl solution was investigated. Both FeCoCrNiMo0.2 exhibit a single-phase FCC structure. Due to remelting multiple heat treatments during preparation coating, small amount σ μ phases appeared coating. microstructures two from bonding area top...
ABSTRACT The morphology of LPSO phase, mechanical properties and fracture behavior Mg-8Gd-5Y-2.5Zn-0.6Zr (wt%) alloy were systematically studied. microstructure as-cast homogenized alloys is mainly composed α-Mg matrix Mg12(Gd,Y)Zn eutectic phase (LPSO phase). contains a large number fine block 18R phases, which can be transformed into lamellar, rod-like 14H phases after homogenization at 520°C for different time. Homogenization treatment significantly improve the alloy, especially...
The microstructure, mechanical properties and fracture behavior of as-cast Mg-10Gd-3Y-xZn-0.6Zr (x = 0, 0.5, 1 2 wt%) alloys have been investigated by X-ray diffraction (XRD), optical microscopy (OM), scanning electron (SEM) tensile tests. experimental results reveal that the microstructure alloy without Zn contains α-Mg Mg24(Gd,Y)5 phase, with 0.5% contained α-Mg, (Mg,Zn)3(Gd,Y) Mg24(Gd,Y,Zn)5 whereas when content was 1% 2%, Mg12(Gd,Y)Zn phase some needle-shaped stacking faults notably...
High-entropy amorphous alloys designed based on the concept of multi-principal components have comprehensive advantages high passivation element content and structure, are considered as one promising alternative protective materials in extreme marine environments. However, composition traditional alloys, design significantly reduces its glass forming ability. In order to improve formation ability high-entropy this study attempts Fe19.6Co19.6Ni19.6Cr19.6(B13.72Si5.88)19.6Y2 alloy by...
The microstructure evolution and mechanical properties of Mg−15.3Gd−1Zn alloys with different Al contents (0, 0.4, 0.7 1.0 wt.%) were investigated. Microstructural analysis indicates that the addition 0.4 wt.% facilitates formation 18R-LPSO phase (Mg12Gd(Al, Zn)) in Mg−Gd−Zn alloy. Al11Gd3 Al2Gd increase content, while content (Mg, Zn)3Gd decreases. After homogenization treatment, Zn)3Gd, some phases are transformed into high-temperature stable 14H-LPSO phases. particulate Al−Gd can...

In order to solve the problem that vehicle sideslip angle is difficult be measured online in process of stability control, a estimation method based on DNN-EKF algorithm fusion proposed. This combines DNN and EKF estimate centroid. adopts network calculate error between actual value estimated value, then put compensation for status EKF, thus compensate correct EKF. The experimental results show accuracy 70% 80% higher than respectively, so has good robustness.
The effects of trace additions Ti and Al on the microstructure mechanical properties Mg-Gd-Zn alloy were investigated. Trace addition can promote generation LPSO in Mg-Gd-Zn(-Ti) alloys. not only effectively refine as-cast alloys, but also inhibit growth DRXed grains as-rolled maximum texture intensity is slightly weakened by Al. aging hardening response be improved adding Ti, decreased fibrous 14H phases, refined grains, basal fine precipitates endow peaked-aged Mg-Gd-Zn-Al-Ti with superior...
