Determination of Bulk Residual Stress Distribution of Superhard SiC-Diamond Samples in Dependence of Heat Treatment and Machining
Determination of internal stress distribution in the bulk stresses in the bulk of SiSiC ceramics and the change of the distribution by different heat treatments to generate an understanding of the relaxation and as a consequence to generate materials with homogeneous stress fields in the material. IKTS is engaged in the development of such materials as well as wear resistant superhard SiC-Diamond materials produced without high pressure. Therefore, test pieces also of such materials with well-controlled different thermal history would be prepared for the stress measurement in the bulk. The result of the measurement could be introduced into finite element models, describing the infiltration of such materials. This would allow better to understand the material formation and behaviour as well as to achieve more reproducible production and more reliable data.
