Microstructural effects on the mechanical behavior of B-modified Ti–6Al–4V alloys
TLDR
In this paper, microstructural properties of hot isostatically pressed Ti-6Al-4V alloy with 0, 0.05, 0., 10, and 0.40 wt.% B additions have been examined, with particular emphasis on identifying the micro-structural length scale (grain size vs. lath size) that controls the mechanical properties of these alloys.About:
