Ion beam modification of metals: Compositional and microstructural changes
(Elsevier, 1989)
Ion implantation has become a highly developed tool for modifying the structure and properties of metals and alloys. In addition to direct implantation, a variety of other ion beam techniques such as ion beam mixing, ion ...
Similarities in the fracture surface features of borosilicate and polymer glasses
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1989-10)
Considerable similarity exists between the features on the fracture surfaces of a borosilicate glass and those on the fracture surfaces of polymer thermoset glasses like epoxies and vinyl esters. These features include the ...
A petrographic thin sectioning technique for evaluating composite materials
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1989-08)
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 ...
Toughening mechanisms in elastomer-modified epoxies
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1986-07)
Some brittle epoxies can be toughened significantly by the addition of an elastomeric phase. A great deal of controversy still exists on the nature of the toughening mechanisms. In this work tensile dilatometry at constant ...
Toughening mechanisms in elastomer-modified epoxies
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1989-07)
The role Of matrix ductility on the toughenability and toughening mechanism of elastomer-modified, diglycidyl ether of bisphenol A (DGEBA)-based epoxies is investigated. Matrix ductility is varied by using epoxide resins ...
