Abstract Scope |
The environmental concerns to save energy are driving the attention toward alternative ways to match light alloys with innovative manufacturing processes. Moreover, the need to increase the material formability has led the adoption of local heat treatment to gain relevance over the last years. The present work is focused on the evaluation of the room temperature formability of thin walled Aluminium alloy tube locally annealed by laser. The formability limits were preliminarily determined in the “as-received” conditions (tube expansion with elastomer). Numerical analyses were performed to define the experimental conditions to obtain different strain paths. Tube expansion tests were assisted by the Digital Image Correlation (DIC). Subsequently, the local laser treatment was investigated and Locally Annealed Tubes (LATs) were subjected to tube expansion tests. LATs strain paths and failure strains were compared to those in the “as-received” condition, allowing to evaluate the effect of the local modification on the formability. |
