IPC: C22C14/00
Filed: 1994-05-20
Abstract: PURPOSE:To produce an Ni-Ti shape memory alloy with the oxygen content effectively reduced to prevent the cracking, bending and breaking in cold working by adding an Ni-Ca alloy to a melt consisting essentially of Ni and Ti to remove oxygen. CONSTITUTION:An Ni-Ti shape memory alloy consisting essentially of Ni and Ti is produced as follows. Namely, the raw material is melted down, and then an Ni-Ca alloy is added to the melt in an inert gas atmosphere to remove oxygen. At this time, the Ni-Ca alloy is added so that the content of Ca remaining in the ingot is controlled to <=100ppm and the oxygen content to <=0.06%. A high-quality Ni-Ti shape memory alloy which is not cracked, bent or broken in cold working is obtained in this way.
