| 摘要 |
An elastic component for a precision measuring instrument is made from an austenitic metal alloy containing less than two percent ferrite, less than two percent martensite, and more than eleven percent chromium. The crystalline texture has a nano-structure with blocked dislocations. The manufacturing process includes cold hardening followed by thermal aging between 200° C. and 700° C. The benefits are low anelasticity, freedom from creep and hysteresis, resistance to corrosion, and a low magnetic permeability. Examples are load cells used in analytical, motion-guiding mechanisms, coupling elements and pivoting elements.
