Abstract
Electrical conductivity measurements have been used in quantitative state e valuation for particle contacts in fibrous copper pressings at early stages of sintering under vacuum. The results agree with ultrasonic data and stre tching tests. Contact formation in such a material begins after the specime n has been heated to 600-800 degrees C, i.e., after the complete relaxation of the residual stresses accumulated in the pressure working.
