Phase and microstructural characterisation of B4C samples were carried out using X-ray diffraction (XRD) and scanning electron microscopy (SEM). XRD results displayed some degradation of the...

In this investigation, aluminium-silicon-based alloy (LM6) with the addition of (0, 2.5, 5, and 10%) copper-coated short steel fiber and 5% boron carbide (B4C) element-strengthened composites was...

X-ray diffraction (XRD) patterns were employed to determine the optimum synthesis temperature and atmosphere based on the detection of B4C peaks as the desired product and...

2021年8月1日 · B4C and SiC were characterized by FTIR-ATR and XRD analyses. Knowing the surface properties of ceramic materials is important to determine the area of use. The carbide-based ceramics namely boron carbide and silicon carbide were synthesized and characterized.

2018年12月1日 · With decreasing particle size, no obvious XRD peak broadening is found for B 4 C phase because the smallest particle size of the four powders is still out of the range of nanometres in which the size effect happens.

2020年1月1日 · The XRD analysis reveals that both the phases (ZrB 2 and B 4 C) distinctly present in the composite. Rietveld refinement was analyzed using the data obtained by XRD, which shows the crystal structure is well distributed and occupied with Zr, B, C atoms.

利用差热分析和XRD分析确定了Ti与B4C发生化学反应的温度和1600℃保温0.5h后的物相组成,通过Ti-B4C扩散偶对反应机理进行了研究,实验结构表明在反应过程中扩散路径是:Ti/TiC/TiB/B4C,在扩散偶中Ti与B4C作为反应相始终存在,生成物中TiB2,TiB和TiC三相同时存在,而对于粉料 ...

In this research, the effects of synthesis temperature, holding time, and furnace atmosphere on the synthesizability of B4C ceramics using glucose and boric acid as the starting materials were...

The XRD confirms these results (Figure 1C), evidencing two phases: boron carbide and a graphitic fraction. The phase B 4 C presents broad peaks, indicating the presence of very small crystallites. Figure 1.

2011年2月11日 · B4C boron carbide thin films deposited by radio frequency magnetron sputtering in the temperature ranging from room temperature to 650 °C are amorphous. In this article, pair distribution function (PDF) and Fourier transform infrared (FTIR) spectroscopy were used to characterize the short range order (SRO) structure of amorphous B4C thin films.
