It has been thought for some time that there may well be a yield point in steel due to hydrogen. This letter is to describe experiments that demonstrate the presence of such a yield point. The base material used was commercial hotrolled SAE 1020. The specimens were plungeground from l/2 in. rod to

T, is the temperature at which the surface tension is measured. The density p must also be corrected, using the bulk coeilicient of expansion. Using a factor o = 9 and without making any temperature corrections, relatively good predictions are made for the surface tension of many metals. Table 1

From measurements of Luder's band-front velocities it is concluded that hydrogen does not affect the activation energy for separating a dislocation and its atmosphere and thereby the delay-time for yielding. Suppression of the upper yield point by hydrogen seems rather to be caused by local stresses
