no. 2 Embodiment

[0036] Samples were produced under the same conditions as in the first example except that an aging treatment was performed at 90° C. for 10 days, and the Young’s modulus was measured. The results are shown in Table 2. In addition, the Young's modulus calculated using the above-mentioned formula 1 is collectively recorded in Table 2.

[0037] [Table 2]

[0038]

[0039] As shown in Table 2, the Young's modulus calculated using the formula 1 is very close to the measured value, confirming the correctness of the selection of Cu, Zn, Ag, and Li.

[0040] 3. The third embodiment

[0041] In addition to ingredients and aging treatment conditions are figure 2 Except for the cases shown, aluminum-based alloy samples were produced under the same conditions as those in the first example. according to figure 2 It can be seen that when the aging temperature is 170° C., a Young's modulus of 77 GPa or more can be obtained by aging for 240 hours. It was also confirmed that, when ...

Abstract

Provided is an easily-machined aluminum-based alloy having a simple production process, with which it is possible to achieve high rigidity without containing hard particles such as a ceramic. In an aluminum-based alloy having aluminum as the main element, an aluminum-based alloy represented by general formula (1) (where, X and Y in the general formula are each selected from Cu, Zn, Ag, and Li, a and b are mass% and are within ranges that permit forming a solid solution by solution heat treatment). Al-aX-BY (1)

Description

technical field [0001] The present invention relates to an aluminum-based alloy having a high Young's modulus by solid-solving special additive elements in the aluminum parent phase. Background technique [0002] Although the application of aluminum alloys has become more widespread as the demand for weight reduction of vehicles and aircrafts has increased, there is a rigidity caused by a decrease in Young's modulus when replacing the conventional iron-based materials with aluminum materials. Reduce the problem of enlargement. In order to cope with such a problem, conventionally, rigidity has been improved by utilizing the combined effect of aluminum and ceramics (for example, Patent Documents 1 to 4).
