Mechanical Properties of Aluminum Alloys by Instrumented Indentation: Case Study on Almigo Hard
View through CrossRef
This paper presents a case study of instrumented indentation for assessment of mechanical properties of a specific Almigo Hard aluminium alloy. It shows that conventional microhardness is not suitable for local testing of this material and that instrumented indentation can reveal significantly more information about the tested material such as Young’s modulus and elastic-plastic characteristics. The study compares mechanical and elastic-plastic properties of the Almigo Hard, aircraft Al alloy and reactor vessel ferritic steel by single peak load and cyclic indentations in order to demonstrate superior properties of the Almigo Hard alloy.
