| Abstract |
The effect of prestrain on creep phenomena to low carbon steel has been investigated. Prestrain was changed from 0 to 7.1% for 0.1% c-steel and from 0 to 5.59% for 0.43% c-steel. Prestrain over the yield point was resulted in the uniform plastic deformation by increasing load. Creep was examined in the range of temperature from 400℃ to 500℃, and of stress from 24.59(0.1% c-steel) to 34.68㎏/㎟(0.43% c-steel). Creep strength rises with increased prestrain and carbon content. The ratio transition creep rate against steady creep rate was increased with increasing prestrain and carbon content. |
