Embodiment Construction

[0016] The core of the present invention is to provide a method for homogenizing 2060 alloy, which avoids severe element segregation and ensures sufficient homogenization of the chemical composition of the alloy.

[0017] In order to enable those skilled in the art to better understand the technical solutions provided by the present invention, the present invention will be further described in detail below in conjunction with specific embodiments.

[0018] A kind of 2060 alloy homogenization method provided by the present invention comprises the following steps:

[0019] The first step: when the temperature of the heating furnace is below 275°C-285°C, the 2060 alloy is put into the heating furnace, and the furnace is charged.

[0020] Step 2: Set the temperature of the heating furnace to T1: 450°C-475°C. After the measured temperature of the 2060 alloy reaches the set temperature T1 or within 5°C of the set temperature T1, keep it warm for 7.5h-8.5h;

[0021] Step 3: Set the ...

Abstract

The invention provides a 2060 alloy homogenization method, which comprises the steps of preheating 2060 alloy, carrying out annealing homogenization treatment on the 2060 alloy for two times, and cooling the 2060 alloy, so that severe element segregation of the 2060 alloy is avoided, and chemical components of the alloy are ensured to be fully homogenized.

Description

technical field [0001] The invention belongs to the technical field of homogenization heat treatment methods for eliminating crystal phases of alloy ingots, and in particular relates to a method for homogenizing 2060 alloys. Background technique [0002] The 2060 series alloy belongs to a class of wrought alloys that can obtain the highest aging strengthening effect, and has the characteristics of low density, high strength, and good processing performance. The alloys of this series mainly contain elements such as Mn, Mg, Ag, Zr and Cu. However, due to the high degree of alloying of the 2060 series, Cu elements tend to be enriched at the grain boundaries during the solidification process, resulting in severe dendrite segregation and intragranular segregation. The inhomogeneous distribution of the chemical composition and structure of the grain boundary and the grain boundary will seriously reduce the plasticity of the alloy, deteriorate the hot workability, reduce the streng...
