Evaluation method for delayed fracture resistance |
| abstract |
An object of the present invention is to provide a method for evaluating delayed fracture resistance, which can quickly and accurately evaluate the safety of delayed fracture resistance of bolts and the like in various environments. A method for evaluating delayed fracture resistance includes a step of applying tension to a bolt (tensile test piece), and disposing the bolt with tension in an aqueous solution containing an electrolyte together with a counter electrode. 1 is characterized by including a step of applying a negative potential and a step of waiting for the bolt 1 to be embrittled with hydrogen and broken by hydrogen generated by electrolysis of the aqueous solution A. The negative potential applied to the volt 1 may periodically fluctuate in the range of -0.8 to -1.5 V with respect to the silver-silver chloride electrode. [Selection diagram] Fig. 1 |
