Claims16
A metallic laminate composite comprising:
- a first layer having a low coefficient of thermal expansion material and of a ferritic stainless steel or hardened stainless steel;
- a second layer having a high coefficient of thermal expansion material and of an alloy comprising manganese, nickel and copper, wherein the low coefficient of thermal expansion is between about 4.4 (μin/in)/Deg. F. to about 7.2 (μin/in)/Deg. F., and the high coefficient of thermal expansion is between 12 (μin/in)/Deg. F. to about 18 (μin/in)/Deg. F., and
- a third layer having between about 2% and about 50% of manganese and between about 10% and about 48% of ferritic steel.
A metallic laminate composite comprising:
- a first layer having a low coefficient of thermal expansion material and of a ferritic stainless steel or hardened stainless steel;
- a second layer having a high coefficient of thermal expansion material and of an alloy comprising manganese, nickel and copper, wherein the low coefficient of thermal expansion is between about 4.4 (μin/in)/Deg. F. to about 7.2 (μin/in)/Deg. F., and the high coefficient of thermal expansion is between 12 (μin/in)/Deg. F. to about 18 (μin/in)/deg. F.;
- and,
- a third layer of an iron-nickel alloy that is on an outer surface of the first layer.
A metallic laminate composite comprising a plurality of layers, wherein a first layer is a low coefficient of thermal expansion material comprised of a ferritic stainless steel or precipitation hardened stainless steel and a second layer is a high coefficient of thermal expansion material comprised of an alloy comprising manganese, nickel and copper, wherein the low coefficient of thermal expansion is between about 4.4 (μin/in)/Deg. F. to about 7.2 (μin/in)/Deg. F., and the high coefficient of thermal expansion is between 12 (μin/in)/Deg. F. to about 18 (μin/in)/Deg. F., and, third layer of a low-carbon steel, an austenitic stainless steel, or an iron-nickel alloy.
