Strain and temperature accelerated relaxation in polycarbonate
(John Wiley & Sons, Inc., 1988-11)
The nonlinear viscoelastic behavior of glassy polymers and its relationship to ductile yielding is studied by single- and double-step stress relaxation experiments. In the latter case a small stress relaxation step is ...
Laser-driven micro-explosive bonding of aluminium films to copper and silicon
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1988-06)
Laser explosive microfabrication was used to bond micrometre-thick aluminium films to both copper and silicon substrates. Bonding was observed in both systems for laser intensities greater than about 1 × 10 9 W cm −2 and ...
A quantitative model for the intergranular precipitation of M7X3 and M23,X6 in Ni-16Cr-9Fe-C-B
(Elsevier, 1988-12)
A thermodynamic model has been constructed to explain the details of grain boundary chemistry in Ni-16Cr-9Fe doped with carbon and boron. In this model, Gibbs free energy of the precipitates is calculated using an ideal ...
Fractographic study of transverse cracks in a fibre composite
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1988-07)
Transverse fracture of unidirectional fibre composites was studied in a model glass/epoxy composite in which 1 mm-diameter rods had been used in place of fibres. The fracture surface resulting from transverse cracking in ...
Deformation behaviour of a polycarbonate plate with a circular hole: finite elements model and experimental observations
(Elsevier, 1988-09)
The unique and complex deformation behaviour of ductile polymers has received considerable attention in the polymer field. Much research has been conducted to study the yielding and post-yielding behaviour of polymers. In ...
Analysis of TiN by charged particle beams: Nuclear reaction analysis, nuclear reaction broadening and Rutherford backscattering
(Elsevier, 1988-12-01)
Charged particle beams have been used to extract data both on the composition and also on the thickness of two series of TiNx films (about 5 and 2 [mu]m thick respectively), where x varied from 0.3 to 1.0. The technique ...
