Kinetics of hot-pressing: The exponential form

Journal of Materials Science Letters, 1986
where 0 is the relative density; t is the time (sec); P is the applied pressure (dyncm-2); q is the viscosity (poise); ~ is the strain rate (see-l); A, B are the constants; DE is the lattice-diffusion coefficient (cm 2 s e e l ) ; D b is the grain-boundary diffusion coefficient (cm z see -1); Q is the volume of vacancy (cm3); a~ is the effective stress

Near-net-shape forming of alumina powder under hot pressing and hot isostatic pressing

International Journal of Mechanical Sciences, 1997
Densification and deformation of alumina powder under hot pressing and hot isostatic pressing were investigated. Finite element calculations were performed by implementing constitutive equations for grain growth, power law creep and diffusional creep in the user defined subroutine CREEP of ABAQUS.

Weld strength of laser-welded hot-press-forming steel

Journal of Laser Applications, 2012
There is an increasing demand for ultrahigh-strength steel in automotive industries to facilitate the manufacture of lightweight vehicles without compromising their security features. Although transformation-induced plasticity and dual phase steels have strengths of under 1 GPa, boron-alloyed steel obtained after the hot-press process has a strength of
