摘要

al2214 - 8wt的显微组织和力学性能。对500 nm尺寸的B4C颗粒增强复合材料进行了研究。采用液相冶金工艺，复合材料含8wt。在Al2214合金中产生了%的B4C。为了提高复合材料的润湿性和分散性，将强化颗粒加热至300℃，然后以2个为一组添加到Al2214合金液体化合物的涡流中。采用ASTM标准对Al2214合金和Al2214- 8wt的力学特性进行了分析。%的B4C复合材料。利用扫描电镜和能谱分析证实了纳米B4C颗粒在Al2214合金基体中的分布和存在。XRD分析表明，Al2214合金复合材料中存在B4C相。增加8重量。%的B4C颗粒加入到Al2214合金中，提高了合金的硬度、极限强度、屈服强度和抗压强度。此外，B4C颗粒的存在降低了Al2214合金的塑性。对测试材料进行拉伸断口分析，以确定各种断裂机制。

Evaluation of mechanical behaviour and tensile failure analysis of 8 wt.% of nano B4C particles reinforced Al2214 alloy nano composites

The microstructure and mechanical properties of Al2214-8 wt.% of 500 nm sized B4C particles reinforced composites were studied in this study. By using a liquid metallurgical process, composites containing 8 wt.% of B4C in Al2214 alloy were created. To increase the wettability and dispersion of the composites, fortification particles were warmed to 300 °C and then added in groups of two into the vortex of liquid Al2214 alloy compound. ASTM standards were used to analyse the mechanical characteristics of Al2214 alloy and Al2214-8 wt.% of B4C composites. The distribution and presence of nano B4C particles in the Al2214 alloy matrix were confirmed by microstructural analysis using SEM and EDS. XRD patterns indicated the presence of the B4C phases in Al2214 alloy composites. The addition of 8 wt.% of B4C particles to Al2214 alloy improved its hardness, ultimate, yield, and compression strength. Furthermore, the presence of B4C particles reduced the ductility of the Al2214 alloy. The tested materials were subjected to tensile fractography to determine the various fracture mechanisms.
