Titanium materials microstructure test

Titanium materials microstructure directly affects the performance and service life of mechanical parts, metallographic analysis is an important means of internal quality control of mechanical parts.In new materials, new technology, new product research and development, in scientific research to improve the quality of metal products inner, cannot leave the metallographic analysis technology. TitaniumCN
The so-called "phase" is in the alloy has the same chemical composition, structure and even some of the same atomic state of aggregation.There are obvious separate interface between different phase.Alloy are generally consists of the performance of alloy of each structure performance of the phase and phase combination of decision.The alloy phase structure can be roughly divided into two basic types of solid solution and compounds.
The so-called "metallurgical" is metal or alloy phase structure.
Metallographic examination (or metallographic analysis) is the metallography method is applied to check the metal materials of macro and microstructure of the work.
Metallography: narrow sense of metallography, that is, the alloy phase diagram, with the naked eye observation, with the help of a magnifying glass and microscope, the study of metal and alloy organization and phase transformation.
Microstructure is the concrete forms of metals metallographic, such as martensite and austenite and ferrite, pearlite and so on.Microstructure of generalized refers to two or more substances in microscopic state of mixed state and interaction.

Metallographic microscope is the optical microscope technology, photoelectric conversion technology, computer image processing technology together perfectly and developed into a high-tech product, you can easily observe metallographic images on the computer, and analysis of metallographic atlas, rating and output images, such as printing.It is well known that alloy composition, heat treatment, hot and cold processing technology directly affect the internal organization of metal material, the change of the structure, to make the change on the mechanical properties of the parts.Therefore analyzed by metallographic microscope to observe the inspection of metal internal organizational structure is an important means of industrial production.
Metallographic microscope is mainly composed of optical system, lighting system, mechanical system, the attachment device (including photography or other device such as microhardness).According to different tissue samples of metal on the surface composition of light reflection characteristics, with a microscope in the visible light range for these organizations component in the optical research and qualitative and quantitative description.It can display 500 ~ 0.2 m metal group characteristics of the scale.As early as in 1841, the russians (п п. А н с о kind guide) was studied under the magnifying glass decorative pattern on the Damascus steel sword.To 1863, the British (H.C.S orby) petrography of the method, including sample preparation, polishing and rot engraved technology transplanted to the iron and steel research, such as the development of metallurgical technology, went on to make a batch of low magnification metallographic pictures and other organizations.Soapy and his contemporaries (German arjun artens) and French (f. Osmond) of scientific practice, which laid a foundation for modern optical metallographic microscopy.At the beginning of 20th century, improving optical metallographic microscopy, and widely used in metal and alloy microscopic analysis, so far is still a basic technology in the field of metallography.
