An investigation of diffusivity and solubility of hydrogen in both annealed and as-cold-rolled specimens of an austenitic Type 304 steel has been carried out at room temperature by means of an electrochemical permeation method. Especially, the effect of formation of the “foreign phases”, such as hydride phases (γH, εH…
Abstract The effect of lime on the effective cation exchange capacity (ECEC) and exchangeable cations of 18 New Zealand topsoils was measured. Liming increased ECEC on all soils and the change in ECEC per unit change in pH followed the order yellow‐brown loams > northern and southern yellow‐brown earths > centra…
The rate of formation of tarnish films on silver coupons by vapors generated from organic sulfur compounds, especially dimethyldisulfide, has been measured at room temperature at both high and low relative humidity. The results for freshly cleaned silver coupons, as determined by cathodic reduction methods, indicate t…
The FCC to FCT transformation in Mn–22 at% Cu and –26 at% Cu alloys has been examined by means of X-ray diffraction and optical and electron microscopies with a cooling stage. The c parameter and the c⁄a ratio of the FCT martensite decrease with decreasing temperature, abruptly below the transformation temperature and…
The fatigue and fracture characteristics of polycrystalline Cu-Al-Ni shape memory alloys have been investigated by examining the effect of quenching condition on intergranular cracking, by tensile and fatigue testing and by observing fracture surfaces. The tensile and fatigue tests have been carried out for three defo…
Abstract
The single crystal X-ray analysis of [Au9{P(p-C6H4OMe)3}8]-(BF4)3; has provided the first example of a cluster compound with a metal atom incorporated into the centre of a puckered ring of like metal atoms.
The corrosion resistance of commercial austenitic alloys in the Fe-Cr-Ni-Mo system in marine environments has been reviewed. The types of corrosion examined include intergranular corrosion, stress-corrosion cracking, corrosion fatigue, pitting, crevice corrosion, galvanic corrosion, cavitation damage, and erosion-corr…
The composite structural material comprising paper and wood is analysed in terms of thermal softening and hygroplasticization with regard to its constituent polymers. In particular, an attempt is made to relate the softening occurring under dry conditions to that occurring under moist conditions. It is proposed that t…

The thermotropic liquid crystal mesophase formed by di-isobutylsilanediol has been known for over twenty-five years, but its nature and structure have remained uncertain and the physical characteristics of the phase appeared unique and quite different from those of any other recognised type of liquid crystal. In a pre…

The acidity developed by elemental sulphur when mixed with neutral water has been studied by measurements of the variaiion of pH with changes in the ratio of the solid sulphur to water and the effect of the presenece of metallic iron. The results obtained have been shown to extend the data reported at high temperature…

Parallel screw dislocations performing cyclic slip are considered. Plastic resolved-shear-strain amplitudes γpl below a certain limit γpl,s can be accomplished by a static dislocation density, i.e. by the reversible to-and-fro motion of the screw dislocations. If γpl ≥ γpl,s, steady-state cyclic deformation requires t…
Combination rules for intermolecular potential parameters based on different approximations for the long-range dispersion energy are derived and applied to the Lennard-Jones (12–6) and Kihara potential functions. The resulting group of rules is given by the expressions σ12 = <σ≳j, and ε12 = <εσ6γ≳i/‖&…

Poly-beta-hydroxybutyrate has been identified in the cyanobacterium Spirulina platensis. The addition of reduced carbon compounds to the growth medium was not required for poly-beta-hydroxybutyrate accumulation. Poly-beta-hydroxybutyrate accumulated during exponential growth to 6% of the total dry weight and then decr…
