This standard and GB/T 15014-1994, GB/T 15015-1994, GB/T 15016-1994, GB/T 15017-1994, compared
The main changes are as follows.
--- The standard name changed to "elastic alloy, expansion alloy, thermal bimetal, resistance alloy physical terms and definitions";
--- Added "category";
--- Added "Chinese index" and "English Index";
--- Elastic alloy to remove any "static hysteresis, viscosity, relaxation spectrum, elasticity ratio, stiffness constant, compliance constant" is defined and the "Poisson's ratio wide
Pan-definition "; increase the" elastic alloys, high elasticity "is defined, the" plasticity "is defined on the mechanical properties are described;
--- Expansion alloy part of the increase of the "expansion alloys" is defined;
--- Heat the bimetal part of the definition of "hot bimetallic" be revised; increase the "thermal bimetal passive layer, the active layer of thermal bimetal, horizontal fight
Bi-metal "is defined;
--- Resistance alloy part on the "conductivity" is defined requalified; increase the "resistance per meter" is defined;
--- Mechanical properties of the partial deletion of the "yield point" is defined; increase the "mechanical properties, the yield strength, yield strength at maximum force," the
definition;
--- Definitions of various terms were re-confirmed, some of the terms on the modified text;
--- Physical units corresponding to the relevant national standards, international system of units now using consistent.
The standard proposed by China Iron and Steel Association.
This standard is under the jurisdiction of the National Steel Standardization Technical Committee.

Physical terms and definitions
1 Scope
This standard applies to the elastic alloys, expansion alloys physical terms and definitions in the field, the heat resistance of metals and alloys dual use as a standard
Registration and common appellation general use.
Category 2
This standard functional materials using performance is divided into four categories. elastic alloys, expansion alloys, bi-metal and heat resistance alloy.
3 Terms and Definitions
3.1.1
Divided into high and constant elastic alloy elastic alloys.
3.1.2
The object to change its shape and size of the external force, the external force dismount and then restore the original shape and size characteristics. In the elastic range
Internal stress and strain on simple single-valued function that obey Hooke's law.
3.1.3
Fully meet the elastic behavior of Hooke's law, the external force, while showing four characteristics.
a) momentary appears correspondence relationship between stress and strain;
b) between stress and strain is one to one;
c) when the stress is zero, the strain is zero;
d) between stress and strain is proportional relationship.
3.1.4
In the loading and unloading process, the strain response of different itinerary. Between stress and strain is neither correspondence nor proportionate, but
Still has a third characteristic of an ideal spring.
3.1.5
Size of the object in addition to the non-elastic strain and stress of the size of the phenomenon, but also with time or the speed of deformation.
3.1.6
Flexible incomplete
Resulting in non-linear relationship between stress and strain, the deformation is not perfectly elastic phenomenon. Anelastic manifestations include elastic aftereffect, bomb
Of hysteresis, friction, stress relaxation, modulus, loss and the like.
Anelastic strain ε body expression is.
