How To Test The Quality Of Titanium Alloy Forgings

How to inspect the quality of titanium alloy forgings, titanium alloy as a high-performance materials, widely used in aviation, aerospace, medical and chemical fields. Titanium alloy forgings are metal parts produced by titanium alloy processing, due to its excellent performance and wide range of applications, the quality inspection of titanium alloy forgings is particularly important.
I. Macro-inspection
Surface quality: check the surface of the forging whether there are cracks, folding, inclusions and other defects. These defects will seriously affect the performance and service life of the forgings.
Size inspection: use measuring tools to measure the size of the forging to ensure that it meets the design requirements. For critical dimensions, 100% inspection should be carried out.

Shape inspection: Check whether the shape of the forging meets the design requirements, such as bending and twisting. This is related to the stability of the forgings during assembly and use.
Second, physical property inspection
Density test: Calculate the density of the forging by measuring its weight and size. Compare with the standard value to judge the purity of the forgings.
Hardness test: Hardness is an important index to measure the material performance. Through the hardness test, understand whether the hardness of titanium alloy forgings meets the requirements.
Tensile property test: Through the tensile test, understand the tensile strength, yield strength and elongation of titanium alloy forgings and other parameters to assess their mechanical properties.
Impact performance testing: impact test can reflect the toughness and brittle transition temperature of the material under impact load, which is of great significance for evaluating the safety performance of titanium alloy forgings in practical applications.
