| 摘要 |
A thermocouple bimetal of the type made from a metallic component of high thermal expansion which is bonded to a component of low thermal expansion and in which said component of low thermal expansion consists of a thermally age-hardenable iron-nickel-titanium alloy with 26 to 55% nickel, 1-5% free titanium, 0-16% cobalt, remainder iron including impurities conditioned by the melt, and said component of high thermal expansion consists of a thermally age-hardenable iron-nickel-manganese-titanium alloy with 14-26% nickel, 3-10% manganese, 1-5% free titanium, remainder iron including impurities conditioned by the melt. An advantageous method of producing such a bimetal is also described. |
