Mechanical properties and microstructure of Inconel 625 cylinders used in aerospace industry subjected to flow forming with laser and standard heat treatment
Source abstract
Abstract
The aim of the current study was to obtain a hollow axisymmetric cylinder that can be used in the aerospace industry. Mechanical properties and microstructure of Inconel 625 after cold forming and subsequent heat treatment were analyzed. The results show that due to cold forming process the strength of the workpiece drastically increased (up to 1600 MPa) at the cost of plasticity. To obtain good combination of mechanical properties, the material was additionally using two heating methods: laser and resistance furnace annealing. The main purpose of the experiment was to prepare manufacturing guidelines for aerospace industry requirements. The results obtained in the experiment enabled to obtain a part that meets the requirements of the industry. Additionally, laser and furnace heat treatment were compared as well as their mechanical properties and microstructure of the material.
