Abstract : Bimetallic spring systems of 40% nickel-60% iron alloy combined with Inconel X and type 304 stainless steel exhibit characteristics suitable for applications from -65 to 600 F. In this range the spring constant is held within !0.25%. The general theory of bimetallic, temperature independent helical coil and Belleville type springs is presented. The bimetallic systems tested show that a temperature independent spring is feasible although working stresses must be maintained at relatively low levels. (Author)
