Easy-to-manufacture reference test specimen used for Charpy impact tests at room temperature

Engineering, Metrology, Utilities

Easy to manufacture

The manufacturing process is simple and can be carried out with unsophisticated equipments.

Testing at room temperature

The specimen can be tested at room temperature, which simplifies the indirect verification procedure.

Cost savings

Reducing the complexity of the heat treatment and the possibility of testing at room temperature contributes to reducing the costs of the indirect verification test.

The problem-solution approach

In sectors that demand high precision, such as the materials industry, the reliability of impact tests is crucial. The current complexity in the manufacturing processes of reference specimens poses challenges, from the need for specialized facilities to operation by highly trained personnel, increasing costs and uncertainties in the results.

What is it?

A process for manufacturing a low-energy reference specimen for Charpy impact testing.

How it works

The proposed process consists of simple heat treatment steps, including heating, cooling, hardening, tempering and re-hardening, resulting in low-energy Charpy impact test specimens that can be tested at room temperature. This approach simplifies manufacturing without compromising the accuracy of the results.
