EFFECT OF STRAIN RATE ON CLEAVAGE CHARACTERISTIC STRESS S_(co)OF MILD STEEL
应变速率对低碳钢解理特征应力的影响

In this paper,the low-temperature fracture behavior of a mild steel 16Mn hasbeen investigated at the strain rates of 5.55×10~(-4)/s and 1.1x10~0/s,respectively.The resultsindicated that the cleavage characteristic stress S_(co)is nearly independent of str
