The effect of heat treatment on nano-size B4C particle reinforced hybrid composites is discussed in this paper. For this, AA2219 with 2% by weight nano and MoS2 particulates were fabricated using a two-stage stir casting process, the specimens treated to assess their influence wear behavior. Experiments carried out study behavior varying important factors such as aging temperature, load, slidin...

The various following reinforcements like nanographite, titanium diboride (TiB2), silicon nitride (Si3N4), and aluminum 2219 have all been investigated in this study. Current research suggests that TiB2 graphite may be a suitable reinforcement for Al2219 alloy. stir casting process was used to make reinforced composites on unreinforced Al2219. Compared the Al2219, nanographite-reinforced hybrid...

The lifetimes and the premature wear of machining tools impact on manufacturing efficiencies and productivities. A significant proportion of machining tool damage can be attributed to component wear. Here, titanium aluminium nitride (TiAlN) multi-layered with titanium diboride (TiB2) prepared by PVD (Physical Vapour Deposition) sputtering onto H-13 substrates are studied as potential wear-resis...

Regarding titanium matrix composites (TMCs), their properties strongly depend on the reinforcement material employed for manufacturing; this may lead to a multitude of investigations TMCs. Considering diverse typology reinforcement, six types ceramic particles were tested in investigation: B4C, SiB6, TiB2, TiC, TiN, and BN. In order compare behaviour own influence TMCs, same ratio was starting ...

In this work, a fine-grained structure with a uniform distribution of TiB2 particles and precipitates was achieved in TiB2 particle-reinforced (PR) Al-Zn-Mg-Cu alloys by friction stir processing (FSP). The effects of multi-pass FSP on the microstructure, and TiB2 particle distribution, as well as the microstructural evolution in the following T6 treatment, were investigated by X-ray diffraction...

Abstract: Nano-structural synthesized materials can be fabricated utilizing intensive milling after combustion synthesis. The Al2O3-TiB2 ceramic composite has been synthesized by aluminothermic reactions between Al, Ti (TiO2), and B (B2O3 or H3BO3). Boric acid (H3BO3) is less expensive than boron oxide, and after being dehydrated at 200°C, boron oxide will be obtained. In this study, Al, TiO2, ...

In-situ TiB2/AlSi10Mg composites were prepared by casting, gas atomization, and selective laser melting (SLM), respectively. Microstructural evolution of the in as-cast, atomized, SLMed investigated. Compared with as-cast composite, sample has no texture is composed extremely fine grains crystal cells. The in-situ TiB2 particles uniformly distribute over grain boundaries, acicular Si phase repl...

Aluminium alloy components are used in lightweight engineering applications and lack mechanical properties, wear resistance, corrosion resistance. When hard reinforcement particulates dispersed the aluminium matrix alloy, composites (AMCs) formed. This new material exhibits enhanced properties such as better specific stiffness, strength, elastic modulus, lightweight. AMCs have many favorable co...
