Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard uses redrafted law revision adopted ASTME7-03 "Kim Sang academic language." The main technical content with the same, but the specific
It does not correspond exactly to the preparation of the structure.
For ease of comparison, it is listed in Appendix B of the Standard Terms and ASTME7 Terms reg control list numbered.
As China's actual needs, the standard when using ASTM standard has been modified. Given the difference in the technical appendix C
Its list of different reasons for a control.
The standard proposed by China Iron and Steel Association.
This standard by the National Steel Standardization Technical Committee (SAC/TC183) centralized.
This standard drafting of the main unit. Wuhan Iron and Steel (Group) Corporation, Metallurgical Industry Information Standards Institute.
Participated in the drafting of this standard. Shougang Corporation, Institute of Metal Research, Dongbei Special Steel Group Co., Ltd., China Bing
Ningbo Branch of physical and chemical testing is scientific research center.
The main drafters of this standard. Liuji Xiong, Wang Fen, Luan Yan, Chen Shihua.

Metallographic academic language
1 Scope
This standard defines the terms metallography and metallographic examination and related fields, mainly covering the optical microscopy, micro indentation hardness testing
Test, sample preparation, X- ray and electron metallography, quantitative metallography, microscopic photography, grain size and determination of inclusion content etc. Metallography
Proper nouns widely used in the field.
This standard applies to the field of metallography in research, production, testing, teaching, publishing, preparation of standards and scientific and technological exchanges at home and abroad.
2 Terms and definitions
2.1 term basis
2.1.1
GP zone Guinier-Prestonzones
Al-Cu alloy natural aging and low temperature (150 ℃) artificially aged copper atoms forming the segregation area.
2.1.2
α iron alphairon
At 921 ℃ or less stable, body-centered cubic crystal structure of pure iron.
2.1.3
α copper alphabrass
One or more alloying elements in solid solution in the copper, the copper has the same crystal lattice of the solid solution phase.
2.1.4
β structure betastructure
Structurally similar to a body-centered cubic structure phase (β brass and similar) or with 3/2 electron concentration of binary compounds.
2.1.5
γ iron gammairon
At 910 ℃ ~ 1400 ℃ stable, face-centered cubic crystal structure of iron, non-magnetic solid phase.
2.1.6
δ iron deltairon
In 1400 ℃ ~ 1539 ℃ stable, body-centered cubic crystal lattice structure of pure iron, the solid phase.
Note. Strictly speaking, δ α iron and iron without distinction, but the presence of different temperature ranges.
2.1.7
δ ferrite deltaferrite
δ iron solid solution alloying elements.
Note. The small amount of carbon and a lot of other alloying elements on high and low temperature critical balance of δ ferrite great.
2.1.8
εepsilon
Transition metal alloy system found metal - metal solid solution, the metal - nonmetal mixture.
NOTE. For example, Fe3Mo2, FeSi, Fe3P.
