4.1

4.2

The matrix material category code in cast composite materials shall be represented by the symbol of the metallic element and shall be arranged after the code "ZF".

4.3

When it is necessary to represent the special properties or special operating conditions of cast composite materials, the following can be used to represent the special properties or special operating conditions of cast composite materials.

The condition is indicated by the first one or two capital letters of the Chinese pinyin for the working condition, arranged between the code "ZF" and the matrix material category code.

later.

4.4

The designation of cast composite materials can be represented by "ZF" followed by the matrix material category code and the casting process code, where the casting process code is used.

The process designation is represented by the first capital letter of the Chinese pinyin of the process name, totaling 2 to 4 capital pinyin letters.

Represented by regular letters.

4.5

When indicating the constituent phases of cast composite materials, “-” and the composite material composition should be appended after “ZF” and the matrix material category code.

Code; if the grade designation also includes a casting process code, "-" and the composite material composition code should be appended after the casting process code.

In the composition code of a composite material, the first part represents the reinforcing phase (or hardening phase), followed by a "/", while the second part represents the grade or code of the metal matrix material. Reinforcing

The shape characteristics of materials such as hardening phases can be represented by one or two lowercase English letters in the lower right corner, where f represents fiber, p represents particle, and l represents layer.

4.6

When indicating the model number of a cast composite material, "-" and the model number can be appended after the composite material composition code. The model number is...

Represented by Arabic numerals.
