THE INTRINSIC FATIGUE THRESHOLD OF 25CR2NI2MOV STEEL
Fatigue crack growth tests of 25 Cr2 Ni2 MoV steel with two different heat treatments(550℃× 20 h,580℃× 20 h) were conducted at stress ratios R of 0.1,0.3,0.5 and 0.7,and the fatigue threshold,△K<sub>th</sub>,and microscopic mechanism were investigated.Results showed that △K<sub>th&...
