A method for ultrahigh temperature testing of materials
JHU Ref #: C17945
Value Proposition:
· Ultra-high temperature tensile testing
· Heat specimens up to 3,400 C
· Local Joule (resistive) heating
Unmet Need
Structural material tensile testing involves assessing the safety, reliability, and various physical and chemical properties of the material when exposed to various external conditions. However, many of these tests are largely completed at room temperature. Materials that are stable above 1,400 C temperatures are important for extreme environments such as energy conversion, aerospace applications, and civil defense. The development of novel structural materials is constrained by the inability to perform mechanical testing at ultrahigh temperatures. Therefore, there is a strong need for systems that heat samples to ultrahigh temperatures to better understand the strength and properties of developed materials.
Technology Description
Researchers at Johns Hopkins have developed a system to perform tensile testing of small structural material at ultra-high temperatures. Using local Joule (resistive) heating, sub-scale specimens can be heat to over 3,400
C to assess the strength and properties of materials for various applications.
