Title: Manufacture of copper series shape memory alloy pipe
Inventor: OZAWA KAZUHIRO
IPC: C22F1/00
Filed: 1990-03-28
Abstract: PURPOSE:To easily obtain a shape memory alloy pipe joint free from cracks by casting a copper series shape memory alloy into bar body, cutting it into stock having a prescribed length and subjecting this stock to hot pipe forging at a specified ratio or above of draft. CONSTITUTION:A copper series shape memory alloy in a molten state is fed to a prescribed mold to directly obtain a cast bar body. Next, this cast strip body is cut into a prescribed length to obtain forging stock, which is subjected to hot pipe forging at >=30% draft to obtain a copper series shape memory alloy pipe having a desired shape. By this method, because billet-manufacturing is not required, the process can remarkably be reduced. Furthermore, because the hot pipe forging is executed at >=30% draft, the cast structure of the cast strip body is collapsed into a worked structure, which is formed into a recrystallized structure in which crystalline grains are uniform by the subsequent memorizing heat treatment. The pipe having the above-mentioned shape has small distortion, so that the generation of pipe cracking at the time of the following expanding can be prevented.
