| 内容記述 | 1. Carbon steel springs with globular cementite structure and those with sorbitic structure were discussed in relation to the torque exercised by them and the endurance limit. 2. Rolled carbon steel sheets (C=1.1%) were given 1 hour's anneal at various temperatures and the change in hardness and the residual bending strain was measured. It was found that the hardness was maximum at the annealing temperatures 125℃ and 310℃, and minimum at 650℃～750℃. 3. The sheets were annealed at 800℃ for 2 minutes, quenched in oil and then tempered at various temperatures. Then the hardness and the residual bending strain were measured in relation to the tempering temperature. The optimum temperature at which the quenched sheets are to be tempered in practice was found to be 200°～300℃. | |||||||||
