DIN EN 515:2017-05 EN 515:2017 (E) 4 1 Scope This European Standard establishes temper designations for all forms of wrought aluminium and aluminium alloys and for continuously cast aluminium and aluminium alloys drawing stock and strip intended to be wrought. NOTE Some of these temper
27、 designations may be subject of patent or patent applications and their listing herein is not to be construed in any way as the granting of a license under such patent right. Additional temper designations, conforming to this standard, may be standardized with CEN/TC 132 and AECMA/5 provided: the te
28、mper is used or is available for use by more than one user; mechanical property limits are defined; the characteristics of the temper are significantly different from those of all other tempers which have the same sequence of basic treatments and for which designations already have been assigned for
29、 the same alloy and product; the following are also defined if characteristics other than mechanical properties are considered significant: a) test methods and limits for the characteristics; or b) the specific practices used to produce the temper. 2 Normative references Not applicable. 3 Terms and
30、definitions For the purposes of this document, the following terms and definitions apply. 3.1 temper condition of the metal produced by mechanical and/or thermal processing, typically characterized by a certain structure and specified properties SOURCE: EN 12258-1:2012, 3.6.5 3.2 hot working forming
31、 of a solid metal after preheating Note 1 to entry: Strain hardening may or may not occur during hot working. SOURCE: EN 12258-1:2012, 3.2.3 DIN EN 515:2017-05 EN 515:2017 (E) 5 3.3 cold working forming of a solid metal without preheating Note 1 to entry: Plastic deformation of metal at such tempera
32、ture and strain-rate that strain-hardening occurs. SOURCE: EN 12258-1:2012, 3.2.4 3.4 strain hardening modification of a metal structure by cold working resulting in an increase in strength and hardness with loss of ductility SOURCE: EN 12258-1:2012, 3.2.11 3.5 solution heat treatment heating an all
33、oy to a suitable temperature for sufficient time to allow one or more soluble constituents to enter into solid solution, where they are retained in a supersaturated state after quenching SOURCE: EN 12258-1:2012, 3.7.1 3.6 ageing treatment of a metal aiming at a change in its properties by precipitat
34、ion of intermetallic phases from supersaturated solid solution Note 1 to entry: Ageing can be a treatment at room temperature (natural ageing) or a thermal treatment (artificial ageing). Note 2 to entry: In North America the term “aging” is used. SOURCE: EN 12258-1:2012, 3.7.15 3.7 annealing thermal
35、 treatment to soften metal by reduction or removal of strain hardening resulting from cold working and/or by coalescing precipitates from the solid solution SOURCE: EN 12258-1:2012, 3.6.6 3.8 heat-treatable alloy alloy capable of being strengthened by suitable thermal treatment Note 1 to entry: In a
36、ddition to cold working, heat-treatable alloys are typically strengthened by precipitation hardening. SOURCE: EN 12258-1:2012, 2.2.8 DIN EN 515:2017-05 EN 515:2017 (E) 6 3.9 non heat-treatable alloy alloy which is not strengthened by thermal treatment Note 1 to entry: Non-heat-treatable alloys are o
37、nly strengthened by hot or cold working. SOURCE: EN 12258-1:2012, 2.2.9 3.10 stress relieving reduction of internal residual stresses by thermal or mechanical means SOURCE: EN 12258-1:2012, 3.2.8 4 Basis of codification 4.1 The temper designations are based on the sequences of basic treatments used
38、to produce the various tempers. Property (mechanical or physical) limits apply to individual alloy-temper-product combinations. 4.2 The temper designation follows the alloy designation; these are separated by a hyphen. 4.3 Basic temper designations consists of letters. If subdivisions of the basic t
39、empers are required, these are indicated by one or more digits following the letter of the basic temper. These digits relate to a specific sequence of basic treatments, but only those treatments or operations recognized as significantly influencing the products characteristics are indicated. Should
40、some other variation of the same sequence of basic operations be applied to the same alloy, resulting in different characteristics, then additional digits are added to the designation. 5 Basic temper designations 5.1 F as fabricated This designation applies to the products of shaping processes in wh
41、ich no special control over thermal conditions or strain hardening is applied. For this temper, there are no mechanical property limits specified. 5.2 O - Annealed This designation applies to products which are annealed to obtain the lowest strength temper. The O may be followed by a digit other tha
42、n zero1. 5.3 H Strain-hardened This designation applies to products subjected to the application of cold work after annealing (or after hot forming), or to a combination of cold work and partial annealing or stabilizing, in order to secure the specified mechanical properties. The letter H is always
43、followed by at least two digits, the first indicating the specific combination of basic operations and the second indicating the degree of strain hardening. A third digit indicates the variation of a two digits temper and it is used when mechanical properties, or others characteristics, differ from
44、those of the two digits H temper to which it is added. 1Products achieving the required annealed properties after hot forming processes may be designated as O temper. DIN EN 515:2017-05 EN 515:2017 (E) 7 5.4 W Solution heat-treated This designation describes an unstable temper. It applies only to al
45、loys which spontaneously age at room temperature after solution heat-treatment. This designation is specific only when the period of natural ageing is indicated; for example W 1/2 h. 5.5 T - Thermally treated to produce stable tempers other than F, O or H (for heat-treatable alloys only) This design
46、ation applies to products which are thermally treated, with or without supplementary strain-hardening, to produce stable tempers. The T is always followed by one or more digits indicating the specific sequence of treatments. 6 Subdivision of O (annealed) temper designations 6.1 O1 High temperature a
47、nnealed and slow cooled2This designation applies to wrought products which are thermally treated at approximately the same time and temperature required for solution heat-treatment and slow cooled to room temperature, in order to generate the correct ultrasonic response and / or provide dimensional
48、stability. It is applicable to products which are to be machined prior to solution heat treatment by the user. Mechanical property limits are not specified. 6.2 O2 Thermo-mechanically processed This designation applies to wrought products subjected to a special thermo-mechanical treatment. It is app
49、licable to products which are to be super-plastically formed prior to solution heat treatment by the user. 6.3 O3 Homogenized This designation applies to continuously cast drawing stock or strip, which are subjected to a high temperature soaking treatment to eliminate or reduce segregations, thus improving subsequent formability and or response to solution heat-treatment. 7 Subdivision of H (strain-hardened) temp
