Some studies on stresses and strains of aluminium alloy during extrusion-forging at room temperature
TLDR
In this paper, an attempt has been made to establish a relationship between the approaching angle and protrusion height and to establish the relationship among various height strains and stress ratio parameters, and the relationship was also established between the various bulge parameters namely the hoop stress, the hydrostatic stress and the stress ratio parameter.About:

Forgeability Study of Al 6061 Alloy During Warm Forging of Cylindrical Billets
TL;DR: In this article, the effect of homogenization on forgeability is studied and half of the samples are homogenized at 550°C for 8 hours and the initial raw material and the homogenised samples are warm forged at two different temperatures i.e. 100°C and 150°C respectively.

Phenomenon of barrelling in aluminium solid cylinders during cold upset-forming
R. Narayanasamy,K.S. Pandey +1 more
TL;DR: In this article, the curvatures of the barrelled aluminium cylinders measured physically were found to conform closely with the values calculated using the experimental data, and empirical relationships were found between the measured radius of curvature of the barrel and other variables such as the hydrostatic stress and the stress-ratio parameter.
