Abstract : Data are summarized relating to the effect of dilute impurities upon the recrystallization characteristics of pure metallic elemen s. Correlations are presented relating the electronic structure of the solute and solvent to the changes in recrystallization temperature resultant upon alloying. The implications of these observations with regard to current theories of grain oundary inhibition are discussed. Evidence is presented for a model more dependent upon changes in bulk ch racteristics, the solut interaction with surrounding solvent atoms being of prime importance. The relation of these interactions to electronic structure is discussed. (Author)
