标准范围

本文件旨在作为金属合金PBF和DED工艺的非破坏性可检测缺陷副本的识别和“播种”的最佳实践。描述了三种播种类别:a） 通过CAD设计处理缺陷；b） 构建参数操作；c） 减法制造。这些缺陷包括沉积材料、后热处理或热等静压处理材料中存在的缺陷，以及由于后处理操作而可检测到的缺陷。几何方面或测量不是本文件的主题。警告-本文件无意解决与其使用相关的所有安全问题（如有）。本文件的用户有责任在使用前制定适当的安全和健康做法，并确定监管限制的适用性。

This document is intended to serve as a best practice for the identification and “seeding” of nondestructively detectable flaw replicas of metal alloy PBF and DED processes. Three seeding categories are described:a) process flaws through CAD design;b) build parameter manipulation;c) subtractive manufacturing.These include flaws present within as-deposited materials, post heat-treated or HIP processed material, and those flaws made detectable because of post-processing operations. Geometrical aspects or measurement are not the subjects of this document.WARNING — This document does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
