4 Claims

1. A controlled thermal coefficient product manufacturing method comprising:

(1) plastically deforming a metallic material; and

(2) texturing said metallic material in at least one selected material direction in response to said plastic deforming;

wherein:

said metallic material comprises a material selected from a group consisting of:

(1) a material characterized by a general formula Cu_100-AX_A, wherein X is at least one of Zn, Ni, Mn, Al, Be, or combinations thereof, and A is in a range from 0 to 75 atomic percent composition;

(2) a material characterized by a general formula Cu_100-A-BAl_AX_B, wherein X is at least one of Zn, Ni, Mn, Be, or combinations thereof, and A is in a range from 0 to 50 atomic percent composition, and B is in a range from 0 to 50 atomic percent composition such that A plus B is less than 100;

(3) a material characterized by a general formula Cu_100-A-B-CMn_AAl_BX_C, wherein X is at least one of Zn, Ni, Be, or combinations thereof, and A is in a range from 0 to 50 atomic percent composition, B is in a range from 0 to 50 atomic percent composition, and C is in a range from 0 to 50 atomic percent composition such that A plus B plus C is less than 100;

said metallic material prior to said plastic deformation and said texturing comprises a martensitic phase exhibiting different thermal expansion coefficients in different crystallographic directions;

said texturing comprises texturing of said martensitic phase;

said metallic material, subsequent to said plastic deformation, exhibits a second bulk thermal expansion characteristic having a second thermal expansion coefficient;

said second thermal expansion coefficient is within a selected range; and

said second bulk thermal expansion characteristic is in said at least one selected material direction due to said texturing of said martensitic phase.
