High Temperature Mechanical Properties Testing
The mechanical properties of metal materials at high temperatures are very different from those at room temperature, and the influencing factors are much more complex than those at room temperature. The mechanical properties of materials at room temperature have little relationship with the load retention time, but the material properties at high temperatures have a significant relationship with time. The structure of metal materials may change under high temperature, which makes the performance also change significantly. As the temperature rises, the corrosive effects of the environment and media intensify the material, which will also affect the performance of the material. T, C&A Lab can conduct high temperature mechanical properties testing on various materials according to ASTM and ISO specifications, other standards for materials and application types, and customer requirements.
The high temperature mechanical properties tests we provide include but are not limited to:
High temperature creep
Creep refers to the phenomenon that metal materials slowly produce plastic deformation under the long-term action of constant temperature and constant load. Under the condition of high temperature, the effect of creep on the component is very significant. Due to the different ways of applying stress, it can be divided into high temperature compression creep, high temperature tensile creep, high temperature bending creep and high temperature torsional creep.
A material mechanical performance test to determine the maximum stress that does not cause fracture within a specified duration when the material is subjected to a constant load at a certain temperature. The high temperature endurance strength is an important basis for the design and selection of high temperature components.
There are many parts in power machinery, such as the combined rotor of steam turbine and gas turbine, or the fastening bolts of flanges, springs and hot pressing parts used at high temperature, all work under the condition of stress relaxation. The so-called relaxation refers to the phenomenon that the total deformation of the part does not change at high temperature, but the stress applied therein gradually decreases spontaneously with time.
High temperature fatigue
When the machine parts are subjected to alternating load at high temperature, the phenomenon of fracture occurs after a long time, which is called high temperature fatigue. Under the action of high temperature cyclic loading, the decrease of fatigue life with the decrease of loading frequency, the increase of tensile strain holding time and the increase of temperature is attributed to the interaction of fatigue, creep and environment.
Short-term tensile properties at high temperature
When evaluating the mechanical properties of refractories, short-term tension is not as important as creep and rupture strength, but if the working time is very short, or the working temperature of the part is not high, and the creep phenomenon does not play an important role, and check the thermoplasticity of materials, short-time high-temperature tension is of great significance.
High temperature hardness
High temperature hardness is used to measure the ability of materials to resist plastic deformation at high temperatures. For high temperature bearings and some die materials working at high temperature, high temperature hardness is an important quality index.
