An Experimental Evaluation of the Gerdemann-Jablonski Compaction Equation

Abstract

This paper reports on an attempt to independently evaluate the validity and applicability of a new compaction equation recently presented by Gerdemann and Jablonski [Metallurgical and Materials Transactions A, 42 ( 2011 ) 1325-1333] using experimental data. Furthermore, the rationality of Gerdemann and Jablonski's interpretation of the equation parameters is examined. The results are discussed in terms of the comparative evaluation of four different titanium powders (sponge Ti, CP TiH2, Grade 2 CP Ti, and TiH2-SS316L nanocomposite blend prepared by high energy milling) cold pressed in die to compaction pressures of up to 1300 MPa.
