Abstract

PURPOSE: To manufacture an airplane stringer material with superior characteristics such as mechanical properties, elongation and rupture toughness by homogenizing an Al alloy contg. specified alloying elements followed by hot rolling, cold rolling to a desired thickness and softening by rapid cooling.
CONSTITUTION: An Al alloy a contg. 5.1W8.1% Zn, 1.8W3.4% Mg. 1.2W2.6% Cu, <0.2% Ti and 0.18W0.35% Cr and/or 0.05W0.25% Zr is homogenized at 400W490°C, hot rolled at 350W470°C, and cold rolled to a predetermined thickness at ≥20% reduction ratio to form a structure having ≤100μm grain size. Softening is then carried out by rapid heating to 320W500°C at ≥11°C/min average temp. rising rate. When the cooling rate at this time is ≥30°C/hr, the softened material is reheated to 200W500°C, and when the reheating temp. is 200W350°C and 350W 500°C, the reheated material is air cooled or cooled at ≤30°C/hr rate and cooled at ≤30°C/hr rate, respectively.
