| description | To provide a material for aluminum alloy forging with superior mechanical properties at room temperature, an aluminum alloy forged product and a method for producing the same.SOLUTION: An aluminum alloy forged product has an alloy composition where the ratio (Fe/Mn) of Fe content to Mn content is from 0.3 to 1.2 in mass ratio, with the balance being Al and unavoidable impurities. The cross section of the longitudinal boundary between a long part and a connection part is free of AIFeSi(Mn) compounds with average crystal grain sizes in the alloy structure ranging from 5 μm to 60 μm and average particle sizes of at least 2.0 μm. For fatigue characteristics at room temperature, the fatigue limit at 107 cycles of fracture repetition is at least 150 MPa.SELECTED DRAWING: Figure 1
【課題】常温における機械的特性に優れたアルミニウム合金鍛造用素材、アルミニウム合金製鍛造品及びその製造方法を提供する。【解決手段】アルミニウム合金製鍛造品は、Ｍｎの含有量に対するＦｅの含有量の比Ｆｅ／Ｍｎが質量比で０．３以上１．２以下であり、残部がＡｌ及び不可避不純物からなる合金組成を有し、長尺部と連結部における長手方向の境界部の断面は、合金組織の平均結晶粒径が５μｍ以上６０μｍ以下の範囲内、かつ、平均粒子径が２．０μｍ以上のＡＩＦｅＳｉ（Ｍｎ）化合物を含まず、常温における疲労特性において、破断繰り返し数１０７サイクルにおける疲労限が１５０ＭＰａ以上である。【選択図】図１ |
