In recent years, as a new method developed for machining difficult-to-cut materials, ultrasonic vibration-assisted technology has been attracting more and attentions due to its superior properties in reducing cutting temperature. However, analytical models revealing the mechanism predicting temperature are still needed be developed. this paper, an model was established predict workpiece milling...

In this study, mechanically milled (MM) Al-24TiO2-20B2O3 powder in molten Al7075 matrix was used order to fabricate in-situ TiB2 and Al2O3 reinforcements matrix. Differential thermal analysis (DTA) examination adopted find reaction temperature between Al, TiO2, B2O3 powders. X-Ray Diffraction (XRD) patterns showed the existence of peaks (750 °C at Ar atmosphere) MM powder. Scanning Electron Mic...

Low-temperature oxidation of metal borides particles energetic compounds conglomerates have been studied via thermogravimetry method. By activity can be arranged in the following series TiB2, ZnB2, AlB2, B. Experiment showed change law temperature dependence from logarithmic to parabolic.

Squeeze casting was used to prepare aluminium alloy-6061/titanium diboride (TiB2) create a composite with varied TiB2 quantities. The composite's metallographic structure, tensile strength, and hardness have been explored. strength of produced metal matrix composites increased when particle from 5 10 vol.%. This study uses electrical discharge machining (EDM) investigate the output response too...

In the present work, abrasive and erosive wear of wear-resistant composite coatings with a complex structure different phase compositions deposited on titanium surfaces was studied. The were obtained by electrospark deposition (ESD) using two types hard-alloy compositions: WC–TiB2–B4C–Co–Ni–Cr–Si–B TiB2–TiAl reinforced dispersed nanoparticles ZrO2 NbC. influence ESD process parameters roughness...

Development of aluminium composites by stircasting technique is an effective method for fabrication better quality MMCs. Stircasting one the most commonly accepted techniques. In this research work, Al6061 / TiB2+CeO2 hybrid MMCs have been fabricated with varying wt. % TiB2 (2.5%, 5%, 7.5% and 10%) particulates constant 5% CeO2 particulates. The monolithic alloy composite were hot-rolled at a t...
