Abstract

PURPOSE:To break a tension test piece within gage length and to obtain accurate measured values by providing Vickers dents at random within the gage length of the test piece. CONSTITUTION:Dents are provided in the central part of the gage length L of a tension test piece as shown by X marks to depth <=1/2 the plate thickness by a Vickers testing machine. If this is subjected to a tension test, stresses concentrate in the central part of the test piece because the Vickers dents are provided, and since breaking occurs in the central part, accurate measured values of tensile strength and elongation can be obtained. If at this time the depth of the dents is kept <=1/2 the plate thickness, no changes occur in tensile strength and elongation. The positions where the dents are provided may be random as far as they are within the gage length of the test piece. The number of the dents is preferably >=5 pieces. Accurate tension test can be made with test pieces of <=1mm. plate thickness or wire diamater as well, and the values of tensile characteristics and hardness are obtained simultaneously with one time of testing.
