3.2 Melting Practice

Castings and specimens shall be poured at casting vendor’s facility either from a melt (See 8.2.4) of a master heat, or

directly from a master heat (See 3.4.2 and 8.2.5).

3.2.1 The metal for castings and specimens shall be melted and poured under vacuum without loss of vacuum between

melting and pouring. When authorized by purchaser (See 8.2.6), protective atmosphere may be used in lieu of

vacuum for pouring of castings.

3.2.2 Revert (gates, sprues, risers, and rejected castings) may be used only in the preparation of master heats; revert

shall not be remelted directly without refining for pouring of castings. Melting of revert creates a new master heat.

3.2.3 Portions of two or more qualified master heats (See 3.4.2) may be melted together and poured into castings using

a procedure authorized by purchaser.

3.2.4 If melts (See 8.2.4) are modified by replenishment (See 8.2.7), vendor shall have a written procedure acceptable

to purchaser which defines the controls, test, and traceability criteria for both castings and separately-cast

specimens. Control factors of 4.4.2.2 shall apply.

3.3 Condition

Castings shall be delivered in the as-cast condition.

3.4 Test Specimens

Specimens shall be either separately-cast, integrally-cast (See 8.2.8), or machined from a casting, and shall conform to

3.2.

3.4.1 If specimens are separately-cast, vendor shall have a written procedure acceptable to purchaser. Control factors

of 4.4.2.2 shall apply.

3.4.2 Each master heat shall be qualified by evaluation of chemical, tensile, and stress-rupture specimens.

3.4.2.1 If replenishments are made at remelt as in 3.2.4, frequency of sampling and testing used by the vendor for

qualification to 3.4.2 shall be acceptable to purchaser.

3.4.2.2 Tensile and stress-rupture tests of 3.4.2 are not required if these tests are conducted using integrally-cast

specimens (4.3.3.2) or specimens machined-from-casting (4.3.3.3).

3.4.3 Chemical Analysis Specimens

Shall be of any convenient size and shape.

3.4.4 Tensile and Stress-Rupture Specimens

Shall be of standard proportions in accordance with ASTM E 8/E 8M (See 8.3), and ASTM E 139, respectively.

3.4.4.1 Separately-cast and integrally-cast specimens may be either cast to size, and/or cast oversize and subsequently

machined to 0.250-inch (6.35-mm) diameter.

3.4.4.2 When integrally-cast specimens and/or specimens machined-from-casting are specified, specimen size and

location shall be agreed upon by purchaser and vendor (See 8.2.9 and 8.5).

3.5 Heat Treatment

Not applicable.

摘要：

SAE AMS 5391H-2019 是由美国汽车工程师学会（SAE）发布的最新版本航空航天材料规范，主要规定了耐腐蚀镍基合金的化学成分、机械性能、热处理工艺及质量验收要求。该标准适用于高温、高压及腐蚀性环境下的航空航天部件制造，如发动机涡轮盘、燃烧室衬套及紧固件等。相较于旧版，AMS 5391H-2019 更新了晶粒度控制标准、非金属夹杂物限制及无损检测方法，提升了材料的抗疲劳性能与可靠性。本标准采用固溶热处理与沉淀硬化工艺，确保材料在高达 980°C 的环境中仍保持优异的抗氧化与抗蠕变能力。
