Instrument Name：X-ray stress tester
Serial number for instruments：20160072
specifications and models：X-350A
Date of purchase：2016/1/1
Parameters：Measurement methods: roll fixed ψ method, roll swing method and determination of residual Olympic content; Peak determination method: cross-concern, half width method, parabola method and center of gravity method; 2θ scanning range: 170 o ~ 120 o; The minimum step distance of 2θ scanning is 0.01o；; The minimum step distance of each step in 2θ scanning is 0.01o；; ψ Angle range: 0o ~ 6o; Weight of goniometer: 10Kg；; Total weight of the simplest device: 45Kg；; Power supply requirements: AC 220 V 10% 1000 W 50 Hz; Environment temperature: indoor work requires 15 ~ 25oc, and short-term and intermittent work on site allows 0 ~ 40oc; Relative humidity: ≤85%.
Functions：The residual stress at the designated point and direction of the material surface can be measured nondestructively in a short time (tensile stress and compressive stress are indicated by "+"and "-",respectively), and the algebraic sum of residual stress and load stress is measured when the component is loaded, that is, the actual stress. It is suitable for components made of various metal materials through various technological processes (such as casting, forging, welding, grinding, turning, shot peening, heat treatment and various surface heat treatments). This system is suitable for laboratory research because of its complete functions, and for field measurement because of its portability and flexibility.
