ABSTRACT:
Pressure and mechanical sensors include a sensing component formed of a titanium and tantalum alloy having an elastic (Young's) modulus of less than about 80 GPa and a tensile strength of greater than about 1,000 MPa. The high strength and low elastic modulus, together with very low temperature dependence of the elastic modulus and very low linear thermal expansion, result in high resolution and precise measurement over a large temperature range.
