How to classify the mechanical properties of titanium metal materials?
The properties of metal materials can be divided into:
Mechanical properties: the resistance of metal materials to external forces of different nature, also known as mechanics
performance. Such as: elasticity, plasticity, strength, hardness, toughness, etc. The mechanical properties are stipulated in the standard, you can see the standard, there are high temperature performance, low temperature performance, we usually say the performance is normal temperature performance.
Some standards have high temperature performance, everyone depends on the standard. If the customer asks for performance that is not specified in the standard, do not agree to it casually, but ask people, especially the toughness. It will cost about 1,000 yuan to do a toughness test.
Physical properties: such as electrical conductivity, thermal conductivity, thermal expansion, melting point, magnetic properties, density, etc.
Chemical properties: such as acid and alkali resistance, corrosion resistance, oxidation resistance.
The above three performances are collectively referred to as usage performance.
Process performance: the performance of the material in processing and manufacturing, showing the difficulty of processing and manufacturing
degree, such as: titanium castability, forgeability, weldability, machinability, heat treatment, etc.
Bending, flattening and flaring of titanium tubes.
Some people confuse physical properties with mechanical properties, and often say that samples are taken for physical testing.
Yes, it is actually a mechanical performance test. What he said was wrong.
Note: Mechanical properties and physical properties are different concepts
Physical properties are inherent in themselves and generally do not need to be tested.
