Estimation of Effect of Cold Forging Deformational Behavior on Al-2024 Alloy Reinforced with Fly-Ash Particulates

Abstract:

This work emphasize on utilization of fly ash in to novel aluminium alloy (Al-2024). The Al-2024 alloy and composites (≈10%flyash) prepared by stir casting technique. The composites is cold forged and identified properties (mechanical, structural and stress distribution in component). Upset tests at room temperature, during the deformation process, provide representative behaviour. The metallographic structure of alloy revelled dendritic and composites shows fine spherical prime segment split and regularly dispersed intermetallic compounds. The stress intensity and distribution of temperature were examined in depth at different input combinations. Compression tests were conducted on Ø 12 mm cylindrical specimens at an H/D ratio of 1.0 and 1.5 for alloy and fly ash composites (2, 6 and 10 wt %). In determining the forging load, the upset ratio defined as the mainly important factor. The strain in composites increased with increasing % of reduction in size and decreased with % of fly ash.
