Although suspension spring materials traditionally have been made of steel, metastable beta-titanium alloys are being considered as possible alternative materials. Among their benefits, metastable beta-titanium alloys offer high specific strength, low elastic moduli, high corrosion resistance, and manufacturability. However the cost-effective substitution of metastable beta-titanium for steel will require that titanium suspension springs be manufactured using existing steel suspension fabrication equipment and techniques. These techniques involve coil winding followed by short-time aging and shot peening. This paper describes an evaluation of the effects of the steel suspension fabrication techniques on a prominent metastable beta-titanium alloy.
