| Sumari: | Title screen Developing of wire-feed additive manufacturing process to fabricate high-strength and wear-resistant titanium matrix composites with reduced production time and high cost-effectiveness is challenging. This study demonstrates the ability to produce TiB reinforced Ti-6Al-4V composites using the wire-feed electron beam additive technology. The effect of boriding temperature of titanium feedstock on the microstructure and phase composition of the in-situ TiB/Ti-6Al-4V composites is studied using scanning electron microscopy and X-ray diffraction analysis. Different morphologies of TiB precipitates within prior β grains and along their boundaries are revealed in 3D-printed 1.0 vol% TiB/Ti-6Al-4V and 7.8 vol% TiB/Ti-6Al-4V composites. An increase in the volume fraction of TiB whiskers is shown to enhance both the hardness and scratch resistance of TiB-reinforced Ti-6Al-4V composites. The effect of the TiB whiskers on the ploughing behavior during scratch testing is discussed Текстовый файл AM_Agreement |
