New Test Method for Additive manufacturing for metals -- Qualification principles -- Test method for indentation plastometry
1. Scope
This document describes a test method which covers procedures for carrying out indentation plastometry. This document specifies an indentation-based test technique to determine the stress/strain properties of metallic materials.
This document does not purport to address all of the safety concerns, if any, associated with its use.
Keywords
AM; tensile test; indentation test
Rationale
The tensile test is the gold standard for determining the yield strength and ultimate tensile strength of
metallic materials. The tensile test typically requires machining of a large test coupon and a universal
mechanical test machine. These requirements mean that tensile testing can often be slow and large
sample volumes are required, which makes this method expensive due to the large amount of powder
required, the printing time and sample machining. In addition, it is very difficult to map spatially-varying
properties across a part. In some cases, such as complex parts made by additive manufacturing, it can
be difficult if not impossible to produce a sample where properties can be reliably measured using
conventional tensile testing. This standard for Indentation Plastometry is therefore required to establish
a standardised test method for applying indentation-based tests (coupled with inverse finite element
analyses) to accurately determine tensile properties.
The title and scope are in draft form and are under development within this ASTM Committee.
