Abstract:

The potential application of ceramic materials to structural applications requires mechanical test programs for both material development purposes and for mechanical property evaluation for design purposes. In particular, testing is required not only at room temperature but, more importantly, at elevated temperatures to accurately reflect properties at the working conditions of ceramic components. Typical tests to be performed at elevated temperatures include modulus of rupture in four-point bending, stress rupture in bending, bend creep testing, and fracture mechanics tests such as double torsion. To that end, a simple furnace design was developed at AMMRC that is capable of temperatures of 1500C in air. To date, twelve units have been constructed and these have been used for high temperature MOR tests, bend stress rupture testing, and for routine soak heating of ceramic specimens. Because of the simplicity of design, duplicate furnaces can be made at little cost and with unskilled labor. The furnace is rather small with a modest chamber size. Power requirements are minimal the unit can be operated from a standard wall outlet rated 15 or 20 amperes 110 VAC. In addition, the furnace is portable and weights only 100 pounds.
