摘要： PROBLEM TO BE SOLVED: To provide an aluminum alloy member excellent in impact resistance.SOLUTION: An aluminum alloy member comprises hypoeutectic aluminum alloy constituted by metallic structure having a base part composed of α-Al and a crystallized part composed of the crystallized product except the α-Al. An abundance ratio of the crystallized part to whole metallic structure is 12% or less in terms of an area ratio (whole area ratio) and also an abundance ratio of the crystallized part in the base part to whole crystallized part is 40% or more in terms of an area ratio (an acquisition rate). The aluminum alloy member having such a metallic structure is obtained by heating a pre-finished product composed of a dendrite α-Al particle to a semi-molten state and pressurization-molding the semi-molten pre-finished product. This aluminum alloy member exhibits excellent impact resistance since the aluminum alloy member is composed of such a metallic structure that a weak crystallized part in which a crack is easily propagated is divided by the highly ductile base part (α-Al).
摘要翻译：要解决的问题：提供耐冲击性优异的铝合金构件。解决方案：铝合金构件包括由金属结构构成的亚共晶铝合金，其具有由α-Al构成的基部和由结晶产物组成的结晶部分，除了 α-Al。结晶部分与整个金属结构的丰度比以面积比（全面积比）计为12％以下，基体部分与全部结晶部分的结晶部分的丰度比例为40％以上面积比率（收购率）。具有这种金属结构的铝合金构件通过将由枝晶α-Al颗粒组成的预成品加热至半熔融状态并对半熔融预成品加压成型而获得。这种铝合金构件由于铝合金构件由容易传播裂纹的弱结晶部分被高度延性基部（α-Al）分隔的金属结构构成，因此具有优异的抗冲击性。

摘要： PROBLEM TO BE SOLVED: To provide a raw material for a rolled material, capable of stably obtaining the rolled material of high quality.SOLUTION: The raw material for the rolled material comprises crushed pieces obtained by crushing a rapidly solidified ingot and a compact formed by pess-forming the crushed pieces. The crushed piece is excellent in handleability and hardly causes contamination since it is relatively larger than the size of a powder particle, and even if a previous crushed piece remains, it is visually confirmed and is easily removed by cleaning of equipment or the like. Furthermore, even if a fine crushed piece remains in each equipment, it can be removed in a post classification step. Therefore, the raw material for the high quality rolled material capable of preventing contamination is provided at a relatively low cost. By using the compact formed by press-forming the crushed piece as a billet of the rolled material or the like, a billet for a homogeneous rolled material in which alloy elements are solid-dissolved in a supersaturation state without solidification segregation or the like is provided, and the rolled material of high characteristics is stably provided.
摘要翻译：要解决的问题：为了提供能够稳定地获得高质量的轧制材料的轧制材料的原料。解决方案：轧制材料的原料包括通过粉碎快速固化的锭和通过压碎成形而形成的压块而获得的碎片。破碎片的处理性优异，并且由于粉末粒子的尺寸相对大而难以污染，所以即使以前的破碎片残留，也可以通过清洁设备等来容易地除去。此外，即使在每个设备中保留细碎片，也可以在后分级步骤中去除。因此，能够以较低的成本提供能够防止污染的高品质轧制材料的原料。通过使用通过压制成形为压片的坯料作为轧制材料等的坯料，提供了一种均匀轧制材料坯料，其中合金元素在没有凝固偏析等的过饱和状态下固溶，并且稳定地提供高特性的轧制材料。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a novel aluminum alloy, which is excellent in castability, workability, and mechanical characteristics.
SOLUTION: When the total of the high-strength aluminum alloy is defined to be 100 mass%, the alloy contains 3.5-7.5 mass% Si, 0.45-0.8 mass% Mg, and 0.05-0.25 mass% Cr, with the balance comprising Al and inevitable impurities. The strength of the alloy is improved by containing the proper amount of Mg in an aluminum alloy containing silicon within the range of no-adverse influence to the ductility and is also greatly improved by containing Cr together with Mg in the alloy. In addition, Mg contributes not only to improving the strength of the alloy but also to micronizing eutectic Si.
