Non-Contact Tabletop Mechanical Testing of Ultra-High Temperature Ceramics

Abstract

A 2nd generation creep test system was developed referred to as an EMMA-2 (Electro-Magnetic Mechanical Apparatus). EMMA-2 is capable of performing rapid, low cost creep measurements at temperature >2200 deg C. The system exploits non-contact Lorentz forces to mechanical flexural loads. This system enables Ultra High Temperature Materials of interest for hypersonics to be easily characterized. Testing was performed on ZrBrSC UHTCs creep parameters were extracted and found to be in agreement with published data reported at lower temperatures.
