Investigation of Mechanical Properties and Metallurical Characteristics of a Metallic Chromium and Magnesium Oxide Composite
Abstract
An experimental investigation has been made to evaluate an uncoated thin composite sheet material containing metallic chromium and magnesium oxide for aerospace applications in the temperature range where coated refractory metals also are being considered. The evaluation consisted of mechanical property tests both at room and elevated temperatures up to 2600F. The effect of preoxidation at various temperatures on the room-temperature properties is shown. Bend and tensile transition temperatures were also determined and static oxidation tests were performed up to 2800. The metallurgical study included identification of the oxide films by X-ray analysis and also a study of the solid-state reactions taking place between the chromium and the ceramic material by the use of light and electron microscopy. Fabrication of the composite is discussed briefly. A description of the equipment and procedures utilized in performing the evaluation tests is included.
