Abstract

We thoroughly compare available experimental as well as theoretical values of the strengthening/embrittling energy of numerous solutes at grain boundaries in α-iron and assess their reliability. The strengthening/embrittling energy is displayed according to its relationship to the difference of corresponding sublimation enthalpies of the host and the solute as well as with regard to the position of the solute in the Periodic Table.
