Title:

ALUMINUM ROLLING SIMULATION TEST METHOD AND ALUMINUM ROLLING SIMULATION TEST DEVICE

Document Type and Number:

Japanese Patent JP2023148959

Kind Code:

A

Abstract:

To provide a simulation test method and a simulation test device that can simulate multi-stage rolling.SOLUTION: A simulation test method according to the present invention uses a three dimensionally shaped test piece that has a pair of pressing surfaces facing each other, a pair of extension surfaces located between the pressing surfaces and facing each other in a direction different from that of the pressing surfaces, and a plurality of free surfaces connected to the pressing surfaces and the extension surfaces, which test piece is made of aluminum or an aluminum alloy and includes a lubricant containing portion in at least one of the pressing surface and the extending surface, the method pressurizing the test piece in a stepwise manner in a direction in which the pair of pressing surfaces facing each other approach each other while restraining the extending surface in a state in which a lubricant is contained in the lubricant containing portion, the method then stretching test piece so that the free surfaces of the test piece are separated from each other, and thereby simulating the crystal grain structure and the texture of the test piece after the stepwise stretching.SELECTED DRAWING: Figure 1
