Abstract
PURPOSE: To obtain an inexpensive alloy with sufficiently high reliability by adding a relatively small amount of Cr and/or Co to an Ni-Fe alloy.
CONSTITUTION: This alloy is obtd. by adding 1W3wt% Cr and/or 0.5W5wt% Co to an alloy consisting of 37W43wt% Ni and the balance essentially Fe. After applying a cold working strain, the alloy is annealed in a wet hydrogen atmosphere under about 10-22W10-18 atm. partial pressure of oxygen to obtain a product. By adding Cr and Co to such an Fe-Ni alloy, an oxide film is made dense to enhance the adhesion to the base alloy. Cr and Co added in excess of the upper limit result in an excessively low transition point and an excessively high coefft. of thermal expansion, respectively. By further adding about 0.05W0.35% Si to said composition, the adhesion of the oxide film to the alloy is enhanced to increase the seal bonding strength, yet excess Si lowers the transition point and increases the coefft. of thermal expansion excessively.
