Standard Guide for the Preparation of ASTM E3 Metallographic Samples

Developed by the American Testing and Materials Authority (ASTM), the ASTM E3 standard describes the methods of sampling and preparation for the purpose of investigating subjects such as metallographic metals, their composition, hot and cold processing, machining and examination of microstructures affected by processes such as welding. The full name of the standard is as follows: ASTM E3 Standard guide for the preparation of metallographic samples.

Standard Guide for the Preparation of ASTM E3 Metallographic Samples

The main purpose of metallographic examinations is to reveal the components and structure of metals and their alloys using an optical or scanning electron microscope. However, proper selection and preparation of the sample is of great importance under almost all conditions. Due to the variety of materials used and the various problems encountered, this standard is generally satisfactory.

Metallography is a science that investigates the internal structure of metallic materials using optical and electron microscopy methods. The purpose of metallography science is to deal with the composition, processing and microstructures of metals. It is also concerned with the thickness and uniformity of metallic coatings, the effects of corrosion on the microstructure and the effects of hardening processes such as carburization and nitration on the microstructure. Metallographic testing and analyzer is very useful in quality control studies and damage analysis. is an effective method.

Microstructures have a strong influence on the properties and successful application of metals and alloys. Metallographic examinations are required to determine and control the microstructure.

Many standards contain a microstructure requirement and are used for metallographic examinations. In this context, determining the location and direction of the sample is important to reduce the number of samples required and to simplify the interpretation.

Material testing is an important step in the quality control process of almost all production cycles. In these tests, properties such as hardness level of the components, structure of the material or general material composition are tested.
