GIE GROUP

Nondestructive indentation of metallic components.

Indentation is a nondestructive mechanical technique for the determination of mechanic properties such as yield strength, tensile strength, hardening by deformation coefficients. GIE group has an ESYS 10 equipment and highly trained professionals able to determine the mechanic properties of each in-site component by means of automatic indentation

Service Description

The test consists of performing an indentation, in several cycles, with a spherical tip. Simultaneously, load and displacement are recorded using high-precision and linear analog sensors, and from these, the material parameters are calculated.

The indentation tip has a tungsten carbide ball with a diameter of 1.57 mm, a load measurement cell, and an LVDT for displacement measurement.

The readings taken are stored and then processed by the control and processing software to obtain the points of the tensile curve, on which the parameters of Yield Strength, Tensile Strength, and the Strain Hardening Coefficient and Exponent are finally determined.

Benefits

Optimize your operations by having information about your assets. In most cases, the costs of taking assets out of service, process interruption, lost profits generated, and the operations involved in obtaining a material sample for laboratory testing are usually greater than continuing to operate within safety parameters at low pressures. This latter alternative is usually adopted to the detriment of asset productivity.

Get results without interrupting your operations. The service offered by GIE Group using ESYS 10 indentation instrumentation allows obtaining the mechanical properties of equipment material without the need to take it out of service and send a sample to the laboratory, thus saving on repair costs, plant shutdowns, and lost profits.

Get Results from small samples. Likewise, tensile tests require a sufficient amount of material, which must also be in good condition. With the ESYS 10, small samples such as nuts or keys can be tested.
