Local Heat Treatment in Draw Bending for Profiles of Manganese Boron Steel 22MnB5

Heat treatment of high manganese type X57MnAl27-5 austenitic steel

In the paper, the influence of heat treatment parameters on microstructure and mechanical properties of high manganese type X57MnAl27-5 austenitic steel was investigated. The as-forged bar with diameter of 15 mm were underwent a saturation process at six different temperatures. The microstructural changes of austenite and the influence of heat treatment on the mechanical properties were conside...

Experimental and Numerical Investigation on the Heat Treatment Effects of AA6063 Aluminum Alloy Tubes During Rotary Draw Bending

In this study, the effects of heat treatment of aluminum alloy on the tube bending process were investigated in the rotary draw bending process. As two experimental and numerical simulation methods were used to determine the wall-thinning, ovality, and spring back for extruded, annealed, and aged AA6063 aluminum alloy tubes in different bending angles and bend radii. Numerical simulations were ...

Properties of Boron Steel after Different Heat Treatments

In this article boron steel is analyzed on the example of steel grade B27. In view of the fact that steel is supplied in a state after hot rolling, and the choice of a suitable heat treatment is left to the buyer steel were examined after conventional heat treatments. Steel was studied in state as delivered, after normalization, after quenching and after quenching and tempering at different tem...

Analysis of the Rotary-draw Bending Process for Thin-walled Rectangular Aluminum Tube

The Rotary-Draw Bending (RDB) process is a distinguished process employed for the precision cold bending of a hollow tube with small radius bends using Numerical Control (NC) machines. This research presents an analytical model based on the power law hardening model for the RDB processing of rectangular thin tubes. Based on the constraints of the tube in the dies and its thinness, the plane str...
