In this study, we introduce an innovative approach to significantly enhance the corrosion resistance of magnesium alloys by combining a hydrophobic coating with an Artificial Neural Network (ANN)...

The XRD patterns shown in this study are consistent with the findings published in the existing literature [55, 56, 59]. The XRD spectra indicate reflections originating from five distinct...

2024年8月5日 · Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were employed for microstructural analysis. Because the properties of magnesium alloys are directly related to the atomic structure and texture variation, the microstructure before and after laser treatment was characterized using transmission electron microscopy (TEM) and electron ...

1 天前 · The XRD study of the AZ31 base metal and the WZ of AZ31-Mg RE filler 1, AZ31-AZ31 filler 2, and AZ31-AZ61 filler-3 are shown in Fig. 4. Despite the variations in fillers and the microstructures, XRD profiles of the weldments were produced of the dominant α-Mg (hcp) and β-Mg 17 Al 12 (bcc) phases [40].

2021年11月1日 · In this study, a novel fine-grained AZ31 magnesium (Mg) alloy reinforced with sub-micron vanadium particles (V P) was prepared by powder metallurgy (P/M). It was found that V P could accelerate the pile-up of dislocations and the refinement of Mg crystallite sizes during the milling process.

These samples were characterized by XRD, Fourier Transform infrared (FTIR), element analysis as well as the aqueous residual concentrations of Ni2+ and Fe3+ were detected. The results showed that...

2014年10月29日 · 摘要:使用xrd、om、sem-edx以及wd/ed-cma等技术研究了az31铸造镁合金的物相、显微组织及主要元素分 布。 结果表明:AZ31铸造镁合金由α-Mg基体、共晶体以及弥散分布于晶内的细小析出相组成,是一种典型的铸造离

AZ31 铸造合金的X 射线衍射(XRD)图谱如图 3 所示． 图中2θ 值为37. 10°、32. 88°和35. 04°的衍 射峰可标定为α-Mg 相(六方晶系，空间群P63/ mmc)，与标准卡片的各衍射峰的位置相比，AZ31 铸 造合金中α-Mg 相的各个衍射峰均向高角度方向偏 移约0. 5°．

2024年10月20日 · Therefore, the electrochemical behavior of the AZ31 alloy was examined in NaCl solutions at concentrations of 1 and 3.5% (wt %), and their pH was adjusted to simulate acidic (pH 2) and alkaline (pH 11) solutions. In addition, scanning electron microscopy (SEM), and X-ray diffraction (XRD) were employed to inspect the corrosion products.

为了研究塑性变形过程中孪生-解孪引起的晶粒旋转，利用同步加速器高能 x 射线衍射 (xrd) 和电子背散射衍射 (ebsd) 进行了实验就地压缩-拉伸载荷。 XRD和EBSD数据的比较证实了XRD实验中衍射环的强度变化是由缠绕和解孪引起的。
