Influence of TiB2 addition on friction and wear behaviour of Al2024-TiB2 ex-situ composites

In situ controlled rapid growth of novel high activity TiB2/(TiB2–TiN) hierarchical/heterostructured nanocomposites

In this work, a reaction coupling self-propagating high-temperature synthesis (RC-SHS) method was developed for the in situ controlled synthesis of novel, high activity TiB2/(TiB2-TiN) hierarchical/heterostructured nanocomposites using TiO2, Mg, B2O3, KBH4 and NH4NO3 as raw materials. The as-synthesized samples were characterized using X-ray diffraction (XRD), scanning electron microscope (SEM)...

Study on Machining Parameters of TiB2 Reinforced Aluminum 6063 Composites

In this experimental study, three TiB2/Al metal matrix composites (MMCs) with 40 μm in mean size were produced using a melt stirring squeeze casting route. Test was carried out to find the parameters influencing surface roughness (Ra) and material removal rate (MRR) on machining the TiB2 reinforced Al-6063 composite materials. The orthogonal array, the signal-to-noise ratio, and analysis of var...

Pilot in-Situ Production of AL-TiB2 and AL-ZrB2 Composites Using Reactive Slag

In this research work, the possibility of semi industrial production of Al-TiB2 and Al-ZrB2 composites, using reactive slag in a flame furnace have been investigated. For this purpose, commercial pure aluminum and powder mixture of TiO2 (ZrO2) , KBF4 and Na3AlF6 were used. The results showed that using a proper ratio of slag forming materials as well as proper amounts of the above-mentioned com...
