    Strain induced phase transformations in lead monoxide (1969)
    Copenhagen : International Union of Crystallography (IUCr)
    Applied crystallography online 2 (1969), S. 156-164 
    Details
    ISSN: 1600-5767

    Topics: Geosciences , Physics
    Notes: The strain induced phase transformations produced in lead monoxide powders by ball milling at temperatures ranging from −196 to 200°C have been studied by X-ray diffraction methods. It has been found that either of the two polymorphs, litharge and massicot, was partially converted to the other at all the temperatures investigated, and that, whichever polymorph was the starting material, the end product, after a sufficiently long time, was a mixture of the two polymorphs, both highly strained. The percentage of each phase present was found to be dependent on the temperature of deformation. The results have been interpreted by consideration of the production of the microstrain energy required to overcome the energy barrier to the transformation, and of the shear generated in the mill on the pressure-temperature phase diagram. It is considered that shear stresses can affect the nature of the pressure-temperature phase diagram, in a manner theoretically postulated by Kumazawa. The commercial importance of the results has been briefly outlined.

    Plastic deformation in tungsten carbide (1969)
    Copenhagen : International Union of Crystallography (IUCr)
    Applied crystallography online 2 (1969), S. 249-252 
    Details

    Notes: The practical importance of tungsten monocarbide prompted an investigation into its wear mechanism. Initial studies on ball-milled tungsten carbide powders revealed considerable plastic deformation, coupled with a reduction in crystallite size. Deformation stacking faults, involving slip on the basal plane, were observed. The work was extended to sintered blocks, tool tips and single crystals. Studies on the worn surfaces of these revealed plastic deformation that extended to a depth of a few microns below the surface. The plastic deformation is an important factor in the wear of tungsten carbide.

    Notes: [Auszug] DURING an investigation of the highly complex reaction of co-chloroacetylamino dyes with wool, thin-layer and paper chromatography have been widely used for the detection and identification of the reaction products. From time to time it was noticed that with the dyes used the RF values, relative to ...

    Notes: [Auszug] Using the method described by Williamson and Hall2, strain and crystallite size can be estimated from the integral breadth (p) by plotting ?* (= ? cos ?/?) against d* (= 2 sin ?/?), when the slope gives a measure of the strain, and the intercept on the ?* axis gives a value for the reciprocal of ...

    Notes: [Auszug] SCHOFIELD1 has pointed out the necessity of considering both capacity and intensity factors when assessing the availability of plant nutrients. Plant growth, however, is a dynamic process in which ion transport phenomena are involved, both within the soil and within the plant. Nutrient transport in ...

    Notes: [Auszug] Cellulolytic activity has been recorded previously in several polychaete worms, including Loimia medusa and Sabellastarte indica, whereas reputedly carnivorous forms, such as Glycera chioni, do not seem to possess a cellulase. We have investigated cellulase activity in N. virens by a technique ...
