Abstract

A new hot forging apparatus has been sucessfully developed and applied for the experimental determination of continuum mechanical sintering parameters and theoretical modeling of thin-film sintering. A precise automatic loading system and high-resolution laser measurement system enable accurate measurement of radial and axial strains of cylindrical specimens under constant or intermittent uniaxial loads of 0-5000 N during high-temperature densification. Preliminary experimental results are demonstrated and the key features of technological significance in the design introduced in detail.
