Metallographic Analysis

Metallographic analysis serves as an indispensable technique for the experimental research of metallic materials to understand their intrinsic properties and the changes they undergo during the manufacturing process. This knowledge is essential to increase the efficiency of material utilization and to improve related processing methods.

CD BioSciences-Advanced Materials specializes in advanced materials. We provide efficient metallographic analysis services to help clients understand and improve the properties of their materials. We are committed to helping clients optimize product performance and manufacturing processes through accurate analysis and innovative solutions.

Overview of Metallographic Analysis

Metallographic analysis is a technique employed to study the microscopic structure, crystalline arrangement, and the composition, dimensions, form, dispersion, alignment, and proportion of secondary phases within metallic materials. Furthermore, by integrating quantitative metallographic principles, this analysis can ascertain the three-dimensional configuration of alloy microstructures and establish a quantitative correlation between the alloy's composition, microstructure, and its resultant properties.

Our Services

We provide the following services to help clients advance the development of new materials or improve the performance of existing materials.

Fig.1 Our microstructure analysis of metallic materials.

Microstructure Analysis of Metallic Materials

We observe microscopic features such as crystal structure, grain boundaries, precipitates, and pores of metallic materials through metallurgical microscopy. Using the Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM) we can observe the surface and crystal structure of metallic materials with high resolution.

Alloy Phase Composition Analysis

We use Energy Spectroscopy (EDX) techniques to determine the distribution and content of elements in alloys and offer X-ray Diffraction (XRD) for identifying the different phases in an alloy and their relative amounts.

Second Phase Precipitation Behavior Research

We have advanced Differential Scanning Calorimetry (DSC) and Transmission Electron Microscopy (TEM). The DSC helps us to research the phase transition and precipitation behavior under various thermal conditions, while the TEM provides high-resolution imaging of the precipitation structure.

Heat Treatment Process Research

We use simulation software to predict the temperature field and organization changes during heat treatment and observe the microstructural changes of the heat-treated materials, such as grain size and distribution, by metallographic microscopy.

Our Metallographic Inspection Process

Metallographic testing mainly includes the steps of sample preparation, etching, staining, and microscopic observation.

Cutting, grinding, and polishing of material samples to prepare metallographic specimens.
Etching of the metallographic specimen is carried out to reveal the organization of the material.
Dyeing of the corroded specimens is carried out so that the different organizational structures can be displayed.
Observe and analyze the specimen through the metallographic microscope to obtain the microstructure information of the material.

Our Instrument Platforms

Instruments	Applications
Metallographic Microscope	It is used to accurately observe the organizational structure and phase transformation of metallic materials.
Metallographic Cutting Machine	For cutting samples of various shapes and sizes, ensure that the surface of the cut specimen is bright, flat, and free of burns.
Metallographic Grinding and Polishing Machine	It is used in the processes of rough grinding, fine grinding, and polishing of specimens to ensure that the surface of the specimen is flat for follow-up observation.
Metallographic Inlay Machine	It is used for inlaying tiny, thin, not easy to hold or irregular metallographic and petrographic specimens, so as to facilitate cutting or grinding and polishing of the specimens, and then carrying out metallographic and spectroscopic testing or hardness testing.

Applications of Metallographic Inspection

The applications of metallographic inspection mainly include the following aspects:

Quality Control: Metallographic inspection is a key means to ensure that product quality is up to standard. Through detailed inspection of the microstructure of raw materials, semi-finished products, and finished products, problems in the production process can be detected and corrected in time to prevent the generation of defective and scrap products.
Process Optimization: Analyzing the changes in the microstructure of materials under different process conditions can provide a scientific basis for the adjustment and optimization of the production process, thus improving production efficiency and product quality.
New Materials R&D: In the process of new material R&D, metallographic inspection allows researchers to understand the relationship between the microstructure and properties of materials, and accelerate the process of new material development.
Failure Analysis: Metallographic testing can reveal the microstructural changes in components that have failed or failed, providing important clues for tracing the cause of failure and formulating preventive measures.
