Abstract

The invention discloses a standard sample for Young's modulus performance detection. The standard sample is a solid round rod. Surface roughness of the standard sample is less than or equal to Ra0.8. The standard sample comprises: by mass, 41.7 to 42.5% of Ni, 5.30 to 5.50% of Cr, 2.30 to 2.50% of Ti, 0.60 to 0.70% of Al, less than or equal to 0.4% of C, less than or equal to 0.70% of Mn, less than or equal to 0.70% of Si, less than or equal to 0.02% of P, less than or equal to 0.02% of S, and the balance Fe and other unavoidable impurities. Correspondingly, the invention also provides a preparation method of the standard sample for Young's modulus performance detection. The standard sample for Young's modulus performance detection has stability and high precision, and can satisfy requirements of an elastic alloy measurement field.

Description

technical field [0001] The invention relates to an alloy and a preparation method thereof, in particular to a standard sample for Young's modulus performance detection and a preparation method thereof. Background technique [0002] Elastic alloys are precision alloys with remarkable elastic properties. They are mainly used to manufacture various elastic components, sensitive components and frequency components of high-precision control and measurement equipment, carrier communication terminals, calling and monitoring systems. They are used in aerospace, instrumentation, Indispensable materials in precision machinery and automation devices. [0003] Young's modulus is an important performance index of elastic alloys, and it is one of the basis for selecting materials for mechanical parts, and it is a commonly used parameter in engineering design. Young's modulus is the elastic modulus along the longitudinal direction, which characterizes the physical quantity of tensile or c...

AI Technical Summary

Problems solved by technology

However, there is no standard sample for Young's modulus detection in the performance detection system of elastic alloys at present, which causes the following problems in the Young's modulus performance detection technology of elastic alloys: because the calibration of the detection equipment cannot be implemented, the normal operation of the detection equipment is affected. In the process of testing the Young's modulus properties of elastic alloys, since there is no reliable basis for "data comparison", the accuracy of "evaluation test" is affected, so "measurement accuracy" and "effective supervision of product quality" are both cannot be guaranteed
