SOLUTION: The high-strength aluminum alloy casting has a composition containing 0.1 to 1.0 wt.% of at least one element selected from the group which consists of secondary additive elements of a group consisting of Rb, K, Ba, Sr, Zr, Nb, Ta, V and Pd and rare earth elements. Moreover, when carrying out casting or die casting, the above selected at least one element forms a hydride together with dissolved hydrogen gas in an aluminum alloy to inhibit the casting defects caused by the dissolved hydrogen gas. The method for manufacturing the high-strength aluminum alloy casting comprises the steps of: applying solution heat treatment where an alloy casting is heated at 495 to 505°C for 2 to 6 hr; applying water quenching to the alloy casting after the solution heat treatment; and applying aging treatment where the alloy casting is heated at 160 to 220°C for 2 to 6 hr after the water quenching.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a high-pressure fuel pump equipped with a pump housing that reduces the number of parts and assembling man-hour and has high strength of a slide part and a high-pressure part and high reliability.
SOLUTION: The housing base material of the pump housing casted by lost-wax process is placed in argon atmosphere of 1200°C and 1000 atm for four hours so that the housing base material is subjected to HIP (High Isostatic Pressing) processing. After the HIP processing, a screw thread is cut and processed with a cutting tool or the like in a part of the housing base material where it is screw-joined with another part. The housing base material is then quenched by heat-treating (QT) the housing base material and the hardness of the housing base material is increased. The screw part of the housing base material to be screw-joined with the other part is then annealed to reduce the hardness of the screw part and a cylinder inner peripheral surface of the housing base material is ground with a grinding tool. The other part is assembled to the pump housing thus formed to manufacture the high-pressure pump.
