    • PROBLEM TO BE SOLVED: To provide an iron-base preform for forming a metal matrix composite in which cast-in properties by an aluminum-base alloy are excellent, and stable boundary joining strength and adhesion can be secured, and to provide a journal part structure having the iron-base preform. SOLUTION: A preform body 10 in an iron-base perform 1 for forming a metal matrix composite cast-in by an aluminum-base alloy base material is perforatedly provided with first to fourth through holes 21A to 21D allowing the inner circumferential face 11 and the outer circumferential face 12 to communicate with. In the cast-in stage, the shrinkage in the circumferential direction of the inner circumferential face 11 and the outer circumferential face 12 in the iron-base preform 1 caused by the solidification of the molten metal of the aluminum-base alloy is equally received by the shrinkage caused by the solidification of the molten metal of the aluminum-base alloy intruded into the through holes 21A to 21D, thus the movement of the molten metal in the circumferential direction is suppressed, and further, the generation of a gap in the boundary can be prevented. In this way the cast-in properties are made excellent, and stable boundary joining strength can be obtained. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:提供一种用于形成金属基复合材料的铁基预型件,其中通过铝基合金的铸造性能优异,并且可以确保稳定的边界接合强度和粘合性,并且提供 具有铁基预型件的轴颈部件结构。 解决方案:用于形成通过铝基合金基材铸造的金属基复合材料的铁基执行件1中的预成型体10被穿孔设置有第一至第四通孔21A至21D,允许内周面 11和外周面12连通。 在铸造阶段,由铝基合金的熔融金属的固化引起的铁基预成型体1的内周面11和外周面12的圆周方向的收缩同样地被 侵入到通孔21A至21D中的铝基合金的熔融金属的固化引起的收缩,从而抑制了熔融金属在圆周方向上的移动,此外,边界产生间隙 可以防止。 以这种方式,使铸造性能优异,并且可以获得稳定的边界接合强度。 版权所有(C)2007,JPO&INPIT
