Title:
ALUMINUM ALLOY POWDER FOR HOT FORGING FOR SLIDE COMPONENT, METHOD FOR PRODUCING THE SAME, ALUMINUM ALLOY FORGING FOR SLIDE COMPONENT, AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2017078213
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an aluminum alloy powder which makes it possible to obtain an aluminum alloy powder forging having excellent wear resistance and high-temperature strength, as a forging for a slide component used at high load, such as an automobile engine piston and others, and an aluminum alloy forging for slide components having excellent wear resistance and high-temperature strength, using the aluminum alloy powder.SOLUTION: An aluminum alloy powder for hot forging for slide components comprises Si: 10.0-19.0% and Mn: 3.0-10.0% with the balance being Al and inevitable impurities, with the average size of Si crystal grains of 15 μm or less. The aluminum alloy powder may comprise Cu: 0.5-10.0% and Mg: 0.2-3.0%. An aluminum alloy forging for slide components is obtained by hot forging the powdery extrusion material.SELECTED DRAWING: Figure 1
