PROBLEM TO BE SOLVED: To provide a method for evaluating corrosion fatigue damage, which simply reproduces the corrosion fatigue damage occurring in various members such as an inner cooling hole of a die, by using a test strip.SOLUTION: In a method for evaluating corrosion fatigue damage, a load is repeatedly applied to two surfaces facing each other of a test strip having a corrosion medium introduced in a space formed inside the test strip, and a surface or a cross section of the inside space of the test strip is observed after applying the load. Preferably, in the method for evaluating the corrosion fatigue damage, a space simulating an inner cooling hole of a die is formed in a material strip made of a die material, and the test strip is prepared so as to have the space to which the corrosion medium simulating a cooling medium of the die is introduced, and the load is repeatedly applied to the two surfaces facing each other of the test strip, and the surface or the cross section of the space in the test strip is observed after applying the load. |
