Abstract:
Mar-ageing steels are being specified more and more in advanced
engineering applications, and, frequently, the components are manufactured
from sheet material. Consequently, the evaluation of the sheet forming
properties of this material is of paramount importance; this investigation
forms part of this general program.
The aim here is two-fold, firstly, to determine the maximum strain
which can be sustained under bi-axial stress, and secondly, to suggest any
way in which this value can be increased.
