<P>PROBLEM TO BE SOLVED: To provide a method of thermally treating a high-pressure casting cylinder block. <P>SOLUTION: The method of thermally treating a high-pressure casting cylinder block includes a step of raising the cylinder block to a dissolving temperature, a step of dissolving the cylinder block over a set time period in a set temperature range after raising the temperature to the dissolving temperature, and a step of applying ageing treatment to the cylinder block after the dissolved cylinder block is quenched where the set temperature may be 440 to 460°C, and the set time period may be in a range of one hour to two hours. <P>COPYRIGHT: (C)2013,JPO&INPIT |
