(SFE), has been widely used for aircraft jet engines, gas turbines, marine diesel engines, etc., owing to its excellent combination of properties such as strong corrosion- resistance, high strength... and creep-resistance of alloys [7]. Thus, such high proportions of low-energy twin boundaries are desirable for alloys applied in elevated temperature environments. In the thermal- plastic deformation process......
in various fields such as automobile, aerospace and electronics for their high specific strength, favorable casting capability and ease of recycling [1-5]. However, the bad mechanical properties and poor... materials and automobile industry. 2 Experimental 2.1 Materials and specimens The hot-rolled Mg5Gd alloy was prepared as described previously [26,38]. High-purity Mg (99.9 wt.%) was melted......
. In addition to the dynamic recrystallization (DRx) and dynamic recovery (DRv) during the manufacturing at high temperatures, the microstructures of the alloys are crucial in determining their performance [8... vol.% HClO4 + 34 vol.% CH3(CH2)3OH + CH3OH after being mechanically worked to 40 μm. TEM images were obtained at an acceleration voltage of 300 kV using a Tenai F30. Fig. 1 Schematic......
spectroscopy (EDX) attachment and operated at an accelerating voltage of 200 kV. The samples were electrolytically double jet thinned in an electrolyte containing 10% perchloric acid and 90% ethanol... and Ti is greater than 6.5 wt.% in the precipitation strengthening γ' (Ni3(Al,Ti)) phase, which results in high crack sensitivity and restricts the properties of SLM-treated IN738LC alloy [8,9]. So far......
, high specific strength, high thermal conductivity, bio- compatibility, biodegradability, and environmental friendliness [1-5]. However, their poor corrosion performance limits their more widespread... by dislocations, twins, grain boundaries and grains with high electrochemical activity, and the micro- cathode effect of the β-Mg17Al12 phase on the alloy surface caused the formation of the LDHs......
. First, raw ores with good crystallinity were handpicked to obtain high purity samples. Then, the selected samples were crushed, dry-ground and dry-sieved to collect the maximum amount of 38-74 μm... mineral samples. As shown in Fig. 2, both minerals showed high purity. The polyaspartic acid (PAPA, analytical grade) was employed as the depressant and was purchased from Shandong Taihe Water......
, Ji’nan 250061, China Received 28 July 2020; accepted 28 January 2021 Abstract: The effects of single-stage solution treatment (SST), enhanced solution treatment (EST), high-temperature pre... resistance 1 Introduction Al-Zn-Mg-Cu alloys (7xxx aluminum alloys) are widely used in aeronautic and aerospace engineering due to their high specific strength, low density and good heat treatment......

These results are attributed... for many high-temperature applications, such as sandwich cores in the active thermal protection systems, components of heat exchangers, solar energy volumetric receivers, liners of aircraft high-speed......
investigated optoelectronic materials due to their merits of high absorption coefficient [1], high carrier mobility [2, 3], long electron-hole diffusion length [4, 5], tunable direct bandgap [6, 7], and low... with large-scale, high-throughput R2R manufacturing processes. PSCs are typically classified into two types of device architectures, i.e., conventional structure (n-i-p) and inverted structure (p-i-n......
