Abstract

A controlled thermal coefficient product manufacturing system and method is disclosed. The disclosed product relates to the manufacture of metallic material product (MMP) having a thermal expansion coefficient (TEC) in a predetermined range. The disclosed system and method provides for a first material deformation (FMD) of the MMP that comprises at least some of a first material phase (FMP) wherein the FMP comprises martensite randomly oriented and a first thermal expansion coefficient (FTC). In response to the FMD at least some of the FMP is oriented in at least one predetermined orientation. Subsequent to deformation, the MMP comprises a second thermal expansion coefficient (STC) that is within a predetermined range and wherein the thermal expansion of the MMP is in at least one predetermined direction. The MMP may be comprised of a second material phase (SMP) that may or may not transform to the FMP in response to the FMD.

First claim

What is claimed is:

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-A X 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-B Al A X 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-C Mn A Al B X 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 exhibits a first bulk thermal expansion characteristic having a first thermal expansion coefficient prior to said plastic deformation;
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.

2. The controlled thermal coefficient product manufacturing method of claim 1 wherein said plastic deforming is achieved by at least one of:
(1) hot-rolling;
(2) cold-rolling;
(3) plane strain compression;
(4) bi-axial tension;
