The mechanism of acicular ferrite in weld deposits
TL;DR: In this paper, the authors highlight recent research related to nucleation and growth of acicular ferrite during decomposition of austenite and highlight the possibility to maximize the content of acic ferrite by increasing the intragranular nucleation sites while maintaining a critical weld metal cooling rate and the steel hardenability.

Effect of inclusion size on the nucleation of acicular ferrite in welds
TL;DR: In this paper, the effect of inclusion size on the formation of acicular ferrite lath was examined to understand the role of inclusion in the nucleation of the lath, and it was demonstrated that larger inclusions are indeed more potent nucleation sites when compared with those of smaller size.
