Abstract
Rapidly solidified aluminum base alloy is flow formed into tubes and tubular components using conventional flow forming equipment. A preform of preselected configuration and wall thickness for either forward or back spinning is fabricated. Flow forming is then carried out. The beginning of the flow forming step is offset by leaving undeformed a small section of the preform.
Claims8
A process for flow forming a rapidly solidified aluminum base alloy consisting essentially of the formula Al.sub.bal Fe.sub.a Si.sub.b X.sub.c, where X is at least one element selected from the group consisting of Mn, V, Cr, Mo, W, Nb, Ta, "a" ranges from 2.0 to 7.5 atomic %, "b" ranges from 0.5 to 3.0 atomic %, "c" ranges from 0.05 to 3.5 atomic % and the balance is aluminum plus incidental impurities, the process comprising the steps of:
- a. preparing a preform of preselected configuration and wall thickness for either forward or back spinning;
- and
- b. offsetting the beginning of flow forming by leaving undeformed a small section of said preform.
