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.

Abstract: A pressure relief valve includes a base including a fluid inlet and outlet, a nozzle, and a disc. The nozzle includes a substantially annular seat, a substantially cylindrical seat inlet, and a substantially cylindrical bore in fluid communication with the seat inlet. A ratio between a bore diameter and a seat diameter is a constraint ratio. The disc contacts the seat to seal the fluid inlet to substantially prevent fluid communication between the fluid inlet and outlet when the valve is closed. The disc and the disc holder are adapted to be urged by fluidic pressure such that contact between the disc and the seat is removed at the fluidic pressure to allow fluid communication between the fluid inlet and the cavity. Dimensions of the disc, the disc holder, and the nozzle may be functions of the seat diameter and limited by the constraint ratio.
