Abstract

To provide a forged aluminum alloy excellent in creep characteristics and a manufacturing method for the forged aluminum alloy.A forged aluminum alloy contains Si: 0.10-0.25 mass %, Fe: 0.9-1.3 mass %, Cu: 1.9-2.7 mass %, Mg: 1.3-1.8 mass %, Zn: 0.10 mass % or less, Ni: 0.9-1.2 mass %, and Ti: 0.01-0.1 mass %, with the balance being Al and inevitable impurities, in which the total content of Fe and Ni is 2.2 mass % or less, the total content of Mn, Cr, and Zr is 0.20 mass % or less, the average equivalent circle diameter of an intermetallic compound is 4.5 [mu]m or less, and variation of distance between the intermetallic compounds in the ST direction is 2.3 or less.

Description

technical field [0001] The present invention relates to an aluminum alloy forged material for producing a forged product made of an aluminum alloy having excellent heat resistance and a method for producing the same. Background technique [0002] Conventionally, various proposals have been made as aluminum alloy forging materials. For example, Patent Document 1 proposes an aluminum alloy characterized by containing Si: 0.1 to 2.0 wt%, Fe: 1.0 to 2.0 wt%, Cu: 2.0 to 6.0 wt%, Mg: 1.0 to 3.0 wt%, Ni: 3.0wt% or less, Ti: 0.01-0.2wt%, Si+Fe+Mg≥3.1wt%, the balance is Al and unavoidable impurities, and the electrical conductivity is 25.0% IACS or more and 40.0% IACS or less. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2017-214655 [0006] Generally speaking, the rotating parts and linear motion parts of engines, compressors, turbocharger impellers, etc. are also used continuously at high temperatures. Theref...
