Abstract
Metal matrix composites tiles based on Ti–6Al–4V (Ti64) alloy, reinforced with 10, 20, and 40 (vol%) of either TiC or TiB particles were made using press-and-sinter blended elemental powder metallurgy (BEPM) and then bonded together into 3-layer laminated plates using hot isostatic pressing (HIP). The laminates were ballistically tested and demonstrated superior performance. The microstructure and properties of the laminates were analyzed to determine the effect of the BEPM and HIP processing on the ballistic properties of the layered plates. The effect of porosity in sintered composites on further diffusion bonding of the plates during HIP is analyzed to understand the bonding features at the interfaces between different adjacent layers in the laminate. Exceptional ballistic performance of fabricated structures was explained by a significant reduction in the residual porosity of the BEPM products by their additional processing using HIP, which provides an unprecedented increase in the hardness of the layered composites. It is argued that the combination of the used two technologies, BEPM and HIP is principally complimentary for the materials in question with the abilities to solve the essential problems of each used individually.
采用压烧结混合元素粉末冶金(BEPM)技术制成了以 Ti-6Al-4V(Ti64)合金为基础、以 10、20 和 40(体积分数)TiC 或 TiB 颗粒为增强材料的金属基复合材料瓦片,然后采用热等静压(HIP)技术将其粘合成三层层压板。层压板经过弹道测试,表现出卓越的性能。对层压板的微观结构和性能进行了分析,以确定 BEPM 和 HIP 加工对层压板弹道性能的影响。分析了烧结复合材料中的孔隙率对 HIP 期间板材进一步扩散粘合的影响,以了解层压板中不同相邻层之间界面的粘合特征。通过使用 HIP 进行额外加工,BEPM 产品的残余孔隙率显著降低,层状复合材料的硬度得到了前所未有的提高,从而解释了所制造结构的优异弹道性能。可以说,BEPM 和 HIP 这两种技术的结合对于相关材料来说是一种主要的互补技术,能够解决各自单独使用时的基本问题。
