    An electron microscopy study of the solution treatment of MAR 350 and MAR 400 maraging steels
    (Australian Atomic Energy Commission, 1980-12) Warren, RB; Pollock, JTA; Kelly, PM
    A study of the effect of solution treatment on the microstructure of types MAR 350 and MAR 400 maraging steels has been carried out using transmission electron microscopy (TEM). The aim of the study was to determine the heat treatments needed to produce fine-grained, single-phase microstructures which, after ageing at 500°C were likely to have acceptable combinations of strength, toughness and ductility. The main results are a series of fold out montages which present a detailed description of the microstructure.

    An inclined specimen cartridge for use in the JEM-7A goniometer stage
    (Australian Atomic Energy Commission, 1971-12) Blake, RG; Kelly, PM; Warren, RB
    The inclined specimen cartridge is designed to hold 3 mm discs at a predetermined angle to the beam. The cartridge fits a standard double tilt goniometer stage, no modifications of the microscope are required and the full tilt range of the goniometer stage is still available. Loading and operational instructions are outlined with the aid of a sectional diagram.
