As a result, the researchers discovered that both the physical arrangement and grain boundaries play a vital role in determining the extent of susceptibility of the metal to embrittlement.
因此，研究人员发现物理上的排列和颗粒边界在决定金属脆化敏感程度上起着重要的作用。

The tempering embrittlement results from the precipitation and growth of M_6Ccarbides particles and the segregation of phosphorus at prior austenite grain boundaries.
