MIL-HDBK-5H1 December 1998 — 7075 is a high-strength Al-Zn-Mg-Cu alloy and is availablein a wide variety of product forms. It is also available in several types of tempers, the T6, T73, and T76type. The T6 temper has the highest strength but lowest toughness and resistance to stress-corrosioncracking. Since toughness decreases with a decrease in temperature, the T6 temper is not generallyrecommended for cryogenic applications. The T73 temper provides for much improved stress-corrosionresistance over T6 temper with a decrease in strength. The T76 temper provides for improved exfoliationresistance and limited stress-corrosion resistance over T6 temper with some decrease in strength. Refer toSection 3.1.2.3 for comments regarding the resistance of the alloy to stress-corrosion cracking and to Section3.1.3.4 for comments regarding the weldability of this alloy.The properties of extrusions should be based upon the thickness at the time of quenching prior tomachining. Selection of the mechanical properties based upon its final machined thickness may beunconservative; therefore, the thickness at the time of quenching to achieve properties is an important factorin the selection of the proper thickness column. For extrusions having sections with various thicknesses,consideration should be given to the properties as a function of thickness.Material specifications for 7075 aluminum alloy are presented in Table 3.7.4.0(a). Roomtemperaturemechanical and physical properties are shown in Tables 3.7.4.0(b 1 ) through (g 4 ). The effect oftemperature on the physical properties of this alloy is presented in Figure 3.7.4.0.

MIL-HDBK-5H1 December 1998 — Figures 3.7.4.1.1(a) and (b) permit calculationof residual tensile strengths for complex thermal exposure conditions. They are based upon the rateparameter T(C + log t), in which T is exposure temperature in degrees Rankine, t is exposure time in hoursand C is a constant evaluated for each material. These curves have been verified for use only within theranges of temperatures and exposure times covered in the figures. The following example illustrates theiruse.1 hour.Sample problem: Find F tu at 250F following a complex exposure of 300F, 8 hours plus 350F,1. Reduce given complex exposure by converting 350F exposure to equivalent exposure time at300F.*a. On the 350F single exposure temperature line find 350F, 1 hour.b. From this point move vertically to the 300F exposure temperature line and then readright, 12 hours exposure.c. Total equivalent exposure time at 300F is therefore 8 hours + 12 hours or 20 hours.2. Find F tu at 250F following 300F, 20 hours exposure:a. On the 300F exposure temperature line find 300F, 20 hours.b. From this point move vertically to the 250F test temperature curve and then read left,76 percent F tu .Solution: F tu is 76 percent of the original room temperature F tu . F ty is determined in like manner.F cy can be closely estimated by using the percent reduction factor determined for F ty . For specific data, seeReference 3.7.4.1.Stressed Thermal Exposure — Stress applied during sample and complex thermal exposure of 7075-T6 can have additional effect in reducing material strength. However, the effect becomes significant onlywhen exposure strains exceed 0.2 percent. For specific data, see Reference 3.7.4.1.Figures 3.7.4.1.1(c) through 3.7.4.1.5(b) present elevated temperature curves for variousmechanical properties. Figures 3.7.4.1.6(a) through (m) present tensile and compressive stress-strainand tangent-modulus curves at several temperatures. Figures 3.7.4.1.6(n) through (q) are full-range stressstraincurves for various products. Figures 3.7.4.1.8(a) through (h) provide room-temperature fatigue curvesfor T6 temper products. Fatigue-crack propagation data for sheet are presented in Figure 3.7.4.1.9.Graphical displays of the residual strength behavior of center-cracked tension panels are presented in Figure3.7.4.1.10(a) through (h). — Figures 3.7.4.2.6(a) through (d)present stress-strain and tangent-modulus curves for various products and tempers. Figures 3.7.4.2.6(e) and(f) are full-range stress-strain curves at room temperature for extrusion. Fatigue-crack-propagation data forplate are presented in Figures 3.7.4.2.9(a) through (c). Graphical displays of the residual strength behaviorof center-cracked tension panels are presented in Figures 3.7.4.2.10(a) and (b)._______________________* Choice of reference temperature is optional as long as it permits computation within the bounds of the figures.3-345
