Stress fracture and creep testing methods are very important to understand and prevent product failure, and provide valuable insights into the effect of long-term stress on materials. NG28 aviation laboratory can carry out standard and improved test methods for all kinds of metal materials, especially superalloys.
Stress fracture testing and creep testing are mechanical testing services that provide manufacturers or material suppliers with key data on the performance of their products over time. In the process of testing, the material is kept under a given constant load for a period of time, and the maximum temperature is 1200 ℃ until failure occurs. In this way, our team of experts analyzes the data results to provide important data on long-term physical and thermal stresses.
? Business challenge
If the data of fatigue fracture mechanics test is too discrete, the reliability of the test will be reduced;
Independent verification and verification of equipment alignment is the key to ensure the reliability of data;
? Service content
NG28 aviation laboratory has MTS hydraulic servo fatigue testing machine and high frequency fatigue test. It is equipped with high temperature furnace, strain gauge, extensometer, high and low temperature environment test box and various specifications of test fixture. It can clamp fatigue plates, bars and complex structure test pieces of various sizes. It can test the fatigue performance of various metal materials, composite materials and fasteners under the temperature of - 180 ℃ ~ 1200 ℃ and various corrosion environments.
The fatigue crack growth rate da/dN and crack growth threshold Δ Kth can be measured to obtain a wide range of crack growth DA / DN_ It can test the fracture toughness of KIC, kc-b curve, KIE, JIC, COD and other metal materials.
