ASME核电建造规范中韧性试验的三种模式

ASME第Ⅲ卷核电设备建造规范对设备材料韧性的要求和规定很有特点,不同等级的设备和不同形式的材料有不同要求,既不同于其他国家的核电设备建造规范和标准,也不同于ASME的其他各种常规压力容器规范（第Ⅷ卷）。将分散在第Ⅲ卷的各分卷中材料韧性试验方法归纳为3种模式,并作了较详细的介绍。

Three Modes of Toughness Testing in ASME Nuclear Construction Codes

The material toughness properties requirements specified in ASME nuclear component construction Code（Section Ⅲ） have distinctive characteristics.Different class component and different kind of materials have different requirements.The toughness testing requirements of ASME nuclear Code Section Ⅲ are quite different from those,either in the nuclear standards of other countries,or in common pressure vessel Codes of ASME itself,such as ASME Code,Section Ⅷ.The various requirements of the material toughness test procedures scattered in all sub-sections of sectionⅢ were summarized into three modes in this paper and then were introduced in detail.
