Mechanical testing of powders and powder compacts

• Results from standard triaxial, uniaxial and bending tests are presented. Triaxial tests were performed at pressures in the range 0-200 MPa. Both initial loose powder samples and cylindrical precompacted specimens were studied under hydrostatic conditions. Most of the total volume compaction occurred at pressures below 10 MPa. Triaxial tests with superimposed axial loads showed no softening despite a 30% shortening of the length of specimens which initially were 60 mm long. Specimens deformed in triaxial tests showed a higher density and a higher uniaxial compressive strength than specimens compacted under hydrostatic conditions.
