PURPOSE:To manufacture shape memory alloy pipes in a high yield in a small number of manufacturing stages by pressing Ti-Ni alloy powder into a block and hot extruding it. CONSTITUTION:Ti-Ni alloy powder, a powdery mixture of Ti powder and/or Ni powder with Ti-Ni alloy powder, or a powdery mixture of Ti powder with Ni powder is pressed into a block with a conventional press and hot extruded into a pipe with an extruder. Thus, shape memory alloy pipes whose response speed can be increased by passing a refrigerant are efficiently manufactured.
