Title:
METHOD FOR MANUFACTURING LOAD WHEEL MADE OF ALUMINUM ALLOY
Document Type and Number:
Japanese Patent JP2016132786
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing a load wheel made of an aluminum alloy capable of manufacturing an aluminum wheel having a smaller amount of strain than conventional ones.SOLUTION: There is provided a method for manufacturing a load wheel made of an aluminum alloy including a casting step, a solution treatment step and an artificial aging treatment step. The solution treatment step has a heating treatment step and a hardening step after the heating treatment step. The heating treatment step has a first heating treatment step of heating treating an intermediate after the casting step in a first temperature range set at a temperature T1 in a range of 505 to T0°C, where T0 is an eutectic temperature (°C) of an aluminum alloy, and a second heating treatment step of heating treating the intermediate in a second temperature range set at a temperature T2 in a range of 500 to (T1-5)°C after the first heating treatment step.SELECTED DRAWING: Figure 8
