Processing Response of Boron Modified Ti-6Al-4V Alloy in (alpha+Beta) Working Regime

摘要

Titanium alloys like Ti-6Al-4V are the backbone materials for aerospace, energy and chemical industries. Hypoeutectic boron addition to Ti- 6Al-4V alloy produces a reduction in as-cast grain size by roughly an order of magnitude resulting in the possibility of avoiding ingot breakdown step and thereby reducing the processing cost. In the present study, ISM processed as- cast boron added Ti-6Al-4V alloy is deformed in (alpha + beta )-phase field, where alpha-lath bending seemed to be the dominating deformation mechanism.
