説明
A new testing apparatus where constant load is directly applied to a very small disc-type specimen is developed to evaluate creep lives of components at elevated temperatures: Small Punch Creep (SPC) Testing Apparatus. Since failure of structural components mainly breaks out around maximum damaged portion, and heavily damaged components dominate the residual life of structural systems, a methodology to assess the local damage and residual life in components under creep temperatures have been required. However, conventional uni-axial creep specimens need a certain amount of volume, and this often causes a difficulty to repair specific devices after sampling uni-axial creep specimens. Dimensions of the disc-type specimen here employed are very small: 10mm in diameter and 0. 5mm in thickness. After designing and installing the new SPC testing apparatus, a series of SPC tests were conducted using super duralumin. It is clarified that the primary and the secondary creep regimes occupy most of the creep deformation, and that the tertiary creep appears just before fracute. Furthermore it is shown that creep rupture lives obtained in the SPC test have a good correlation with those from uni-axial creep tests.
