Crack resistance of 15Kh2MFA steel after combined warm-prestressing
Abstract We have studied the influence of parameters of combined warm-prestressing under eccentric tension of compact cracked specimens (temperature, maximum stress intensity factor K1, and its range ΔK) on the critical J-integral Jf, critical opening of the crack tip, and critical stress intensity...

| 520 | |a Abstract We have studied the influence of parameters of combined warm-prestressing under eccentric tension of compact cracked specimens (temperature, maximum stress intensity factor K1, and its range ΔK) on the critical J-integral Jf, critical opening of the crack tip, and critical stress intensity factor of 15Kh2MFA steel at 293 K. The essence of combined warm-prestressing consists of the fact that, at the stage of overstressing of a cracked specimen in the course of its tensile deformation, one imposes a cyclic load of small amplitude. At a temperature of preliminary overstressing of 423 K, which is close to the critical temperature of brittleness of steel (Tk0 = 393 K), combined warm-prestressing decreases the Jf value for steel by a factor of up to 1.5 as compared with static warm-prestressing. At a temperature of 623 K, which exceeds substantially the critical temperature of brittleness of steel, combined warm-prestressing increases the critical J-integral Jf by up to 30% and critical crack opening δfep by up to 14% as compared with warm-prestressing. Irrespective of the temperature (T1 = 423 and 623 K) and scheme of warm-prestressing (combined or static), all experimental values of the critical stress intensity factor Kf depending on δfep are concentrated in a common scatter band and can be described well by a single relation. | ||

Crack resistance of 15Kh2MFA steel after combined warm-prestressing |
| abstract |
Abstract We have studied the influence of parameters of combined warm-prestressing under eccentric tension of compact cracked specimens (temperature, maximum stress intensity factor K1, and its range ΔK) on the critical J-integral Jf, critical opening of the crack tip, and critical stress intensity factor of 15Kh2MFA steel at 293 K. The essence of combined warm-prestressing consists of the fact that, at the stage of overstressing of a cracked specimen in the course of its tensile deformation, one imposes a cyclic load of small amplitude. At a temperature of preliminary overstressing of 423 K, which is close to the critical temperature of brittleness of steel (Tk0 = 393 K), combined warm-prestressing decreases the Jf value for steel by a factor of up to 1.5 as compared with static warm-prestressing. At a temperature of 623 K, which exceeds substantially the critical temperature of brittleness of steel, combined warm-prestressing increases the critical J-integral Jf by up to 30% and critical crack opening δfep by up to 14% as compared with warm-prestressing. Irrespective of the temperature (T1 = 423 and 623 K) and scheme of warm-prestressing (combined or static), all experimental values of the critical stress intensity factor Kf depending on δfep are concentrated in a common scatter band and can be described well by a single relation. © Springer Science+Business Media, Inc. 2007 |
