Abstract

The invention provides a high-mechanical-quality-factor elastic alloy and a manufacturing method of the high-mechanical-quality-factor elastic alloy and belongs to the technical field of elastic alloy. The high-mechanical-quality-factor elastic alloy comprises, by weight, not larger than 0.005% of C, 19.10-21.50% of Ni, 9.00-12.00% of Co, 3.00-6.00% of Mo, 0.40-1.20% of Ti and the balance Fe and inevitable impurities. The high-mechanical-quality-factor elastic alloy is smelted by means of a vacuum induction furnace and is forged to be a square billet with the edge being 60-90mm long, and thenthe square billet is hot-rolled into rod materials. The finished rod materials are processed through two steps of solution treatment at the temperatures of 1050-1150 DEG C and 810-860 DEG C correspondingly, the finished rod materials are aged at the temperature of 480-620 DEG C for 2-8 h, and then the finished rod materials are air-cooled to the indoor temperature. The high-mechanical-quality-factor elastic alloy has the advantages of being high in mechanical quality factor and low in frequency-temperature coefficient and being applied to inertial navigation components, harmonic oscillators and other high-precision elements.

Description

technical field [0001] The invention belongs to the technical field of elastic alloys, in particular to an elastic alloy with high mechanical quality factor and a manufacturing method thereof. Background technique [0002] With the rapid development of modern aerospace, shipbuilding, automobile and other industries, precision components such as inertial navigation components, mechanical filter resonators, resonant cavity oscillators, gyro resonators and other precision components are increasingly miniaturized, lightweight, high-precision and high-sensitivity. The mechanical quality factor and uniform stability of elastic alloys for precision components put forward higher requirements. The mechanical quality factor, that is, the Q value, indicates the degree of energy attenuation of the harmonic oscillator in one vibration cycle. Under the same parameter conditions, the higher the Q value of the device, the larger the amplitude it can maintain, which is more conducive to imp...
