Abstract
The final report is divided in two parts: The aim of the first study was to investigate the kinetics of the grain boundary segregation of phosphorus in three Ni-20%Cr-alloys applying Auger electron spectroscopy. In connection with the grain boundary analysis the strength of these alloys was to be determined from tensile tests. Furthermore, with the same alloys constant strain rate tests were performed under cathodic charging with hydrogen in H{sub 2}SO{sub 4}, to determine the effect of phosphorus at grain boundaries on the hydrogen-induced stress corrosion cracking. The aim of the second study was to investigate the effect of phosphorus additions on the creep behaviour of Ni, Ni-20%Cr and Nimonic 80A. It was concluded that additions of up to 200 ppm P may be useful for improving the creep behaviour of such materials. (MM)
