TLDR
In this paper, an innovative pathway was developed to obtain liquid metal embrittlement-free welds which is able to extend the weldable current range of the steels. But this pathway is limited by the high electrical resistivity of twinning induced plasticity steels, which makes their resistance spot welding difficult and limits their weldability.About:

Liquid metal embrittlement in laser lap joining of TWIP and medium-manganese TRIP steel: The role of stress and grain boundaries
TL;DR: In this paper, the authors addressed LME susceptibility during restrained laser lap joining of high-Mn twinning induced plasticity (TWIP) and medium-mn transformation induced Plasticity (MMn-TRIP) steels, and showed that high angle and special grain boundaries are prone to Znpenetration within the heat-affected zone (HAZ).
