摘要

摘要本研究的目的是利用火花等离子体烧结（SPS）方法研究和制备Ti64蔗渣灰（BA）复合材料。因此，样品是在部分致密化的情况下制造的。采用XRD分析、光学和电子显微镜（SEM）、硬度测量和弯曲试验分别研究了样品的相组成、粉末形态、微观结构和力学性能。结果表明，增加蔗渣灰的体积百分比不仅会影响试样的微观结构，还会影响试样的力学性能。还观察到，在含有5 体积%的蔗渣灰，除了弹性模量的值显著降低之外，所制备的样品还包含具有由陶瓷和金属组成的壁的孔。图形摘要

Investigation of mechanical and microstructure characteristics of Ti64-bagasse ash composite produced by the SPS process

ABSTRACT The aim of this study was to investigate and fabricate a Ti64-bagasse ash (BA) composite using the spark plasma sintering (SPS) method. Accordingly, the samples were fabricated under partial densification. XRD analysis, optical and electron microscopy (SEM), hardness measurement, and bending test were used to study the phases formed, the morphology of powders, microstructure, and mechanical properties of the samples, respectively. The results showed that increasing the volume percentage of bagasse ash affected the mechanical properties of the samples in addition to the microstructure. It was also observed that in the samples containing 5 vol.% bagasse ash, in addition to a significant decrease in the value of elastic modulus, the sample fabricated contained pores with a wall composed of ceramic and metal.
