The invention provides an evaluation method of grain structure uniformity for the aluminium alloy forge piece. The method comprises a grain storage step, a grain static recrystallization step, a metallographic structure surface shooting step, a grain size grade statistics step and a forge piece grain structure uniformity evaluation step. By means of the method, the possibility of evaluating the grain structure uniformity of the aluminum alloy forge piece easily, conveniently and accurately is increased.
Description
technical field [0001] The invention relates to the field of evaluating the uniformity of grain structure of aluminum alloy forgings, and relates to a method for evaluating the uniformity of the overall grain structure of aluminum alloy forgings. Background technique [0002] Although the domestic large passenger aircraft C919 successfully made its first flight in 2017, aero-engines, aircraft control systems, landing gear systems, and large, lightweight and high-strength aerostructures are the key factors that restrict domestic large passenger aircraft from going abroad. Among them, 7XXX aluminum alloy has the advantages of high strength and toughness, good plastic processing performance and heat treatment strengthening, and has become one of the main materials for large-scale lightweight and high-strength aerospace structural parts. [0003] In order to meet the shape requirements of aerospace construction, 7050 aluminum alloy is very commonly formed by forging. There are ...
