Abstract : The effect of quenching on the yield stress of iron was studied at extremely small carbon concentrations. Swedish iron wire specimens of various grain sizes were decarburized until they showed no yield point or strain-aging (70 hours of wet-hydrogen treatment at 716 C). Afterwards they were recarburized in an atmosphere of normal heptane and dry-hydrogen at 716 C and quenched from various temperatures, ranging from 130 to 730 C, into room-temperature water, and tensile tested. Carbon contents were measured by the internal friction technique. (Author)
