description abstract | A technique to achieve stable and uniform uniaxial compression is offered for creep testing of advanced ceramic materials at elevated temperatures, using an innovative self-aligning load-train assembly. Excellent load-train alignment is attributed to the inherent ability of a unique hydraulic universal coupler to maintain self-aligning. Details of key elements, design concept, and principles of operation of the self-aligning coupler are described. A method of alignment verification using a strain-gaged specimen is then discussed. Results of verification tests indicate that bending below 1.5 percent is routinely achievable with the use of the load-train system. A successful compression creep test is demonstrated using a dumb-bell-shaped silicon nitride specimen tested at 1300°C for a period in excess of 4000 h. | |
