The solid–liquid compound casting of Mg-AZ91D and Ti-TC4 alloys was developed by using pure Ni electro-deposited coating. pouring temperatures 660 ℃, 690 720 ℃ 750 were chosen to investigated the effects on microstructural evolution, properties, fracture behaviors Ni-coated TC4/AZ91D bimetals (SLCC). scanning electron microscopy (SEM) energy dispersive spectroscopy (EDS) results showed that interfacial zone mainly composed nickel, Mg2Ni Mg-Al-Ni in cast at ℃. As temperature increased width...
Friction stir welding (FSW) is a common and effective technology used to join metals or alloys of low melting point. However, the FSW Mg alloy joint usually exhibits an unsatisfactory combination strength ductility due intense basal texture formed in welded joint. In this study, large-load low-speed was conducted on AZ61 improve thermal cycling during process. The exhibited ultrafine grain structure with high dislocation density large {10-12} twins. This refinement attributed continuous...
As-cast AlCrFeCoNiCu high-entropy alloy (HEA) was a solid solution of body-centered cubic (BCC) and face-centered phases with typical dendrite interdendrite structures. The precipitated intermediate in 600°C annealed HEA are responsible for the improved hardness. After 1000°C annealing treatment, crystalline re-arranged because decomposition BCC phases. has best corrosion resistance due to its structure. Meanwhile, erosion–corrosion highest hardness wear rate is more than two times lower...
To achieve Ti/Mg bimetallic composite with high strength and metallurgical bonding interface, Al interlayer Zn/Al were used to prepare TC4/AZ91D bimetal interface by solid–liquid compound casting, respectively. was prepared on the surface of TC4 alloy hot dipping, electroplating process. The results suggested that phases across AlTi α(Al) + Mg21(Al, Zn)17 when used. When as interlayer, AlMgTi ternary structure Al12Mg17 δ-Mg eutectic main at interface. shear much higher than pure value...
Ultralight Mg–14Li–1Al alloy sheets were subjected to conventional friction stir welding (FSW) and rapid cooling FSW (RCFSW) for comparative study. Compared with decreasing the rotation rate, use of coolant significantly improved thermal cycle inhibited grain coarsening. The RCFSW600 joint had an ultrafine structure its average size 2.1 μm. yield strength was mainly determined by synergic influences boundaries, dislocations, nanoscale MgLiAl2 precipitations. ultimate tensile 181 MPa...
AZ31B magnesium alloy prepared by conventional friction stir processing (FSP) usually exhibits an intense basal texture, resulting in unsatisfactory strength and ductility. In this work, cooling medium-assisted FSP was conducted on the alloy. The effects of a liquid CO2 coolant thermal cycle, microstructure, mechanical properties zone (SZ) were evaluated. adoption resulted markedly decreased peak temperature increased rate. SZ exhibited fine grain structure with abundant dislocations twins....
The effect of different degrees cold rolling on the short-term oxidation behavior Fe-18Cr-8Ni stainless steel oxidized at 1000 °C in N2-21 vol%O2 for 3 h was investigated. results show that deformation reduces grain size and coincident site lattice (CSL) boundary fraction alloy. When exceeds 20%, mechanism changes from internal to external oxidation. And critical concentration Cr Si required forming protective oxide scale decreases. formation continuous Cr2O3 SiO2 layers alloy prevents...
The austempered ductile iron was austenitized at 900 °C for 1 h and quenched in an isothermal quenching furnace 380 280 °C, respectively. This paper aims to investigate the effects of bainite on wear resistance (ADI) different loads conditions. micro-structure phase composition ADI characterized analyzed by metallographic microscope (OM), X-ray diffractometer (XRD) scanning electron (SEM) with energy dispersive spectroscopy (EDS). results showed that volume fraction retained austenite is...
A series of Al-4Ti master alloys with various TiAl3 particles were prepared via pouring the pure aluminum added K2TiF6 or sponge titanium into three different molds made graphite, copper, and sand. The microstructure morphology characterized analyzed by scanning electron microscope (SEM) energy dispersive spectroscopy (EDS). in their grain refinement efficiency commercial-purity investigated this study. Results show that there morphologies alloys: petal-like structures, blocky flaky...
