Publication number: 20250059636Abstract: A process for producing a copper-beryllium alloy product. The process comprises preparing a base alloy having 0.15 wt %-4.0 wt % beryllium and having grains and an initial cross section area. The process further comprises cold working the base alloy to a percentage of cold reduction of area (CRA) greater than 40%, based on the initial cross section area, and heat treating the cold worked alloy to produce the copper-beryllium alloy product. The grain structure of the copper-beryllium alloy product has an orientation angle of less than 45° when viewed along the direction of the cold working. The copper-beryllium alloy product demonstrates a fatigue strength of at least 385 MPa after 106 cycles of testing.Type: ApplicationFiled: November 7, 2024Publication date: February 20, 2025Applicant: MATERION CORPORATIONInventors: John E. GATEHOUSE, Michael J. GEDEON, Fritz GRENSING, Bruce D. SCHMECK, Jeffrey S. HOYER, Michael F. TYSON, Karl R. ZIEGLER

Patent number: 11980922Abstract: Methods for producing a coiled strip of metal matrix composite (MMC) material are disclosed. The methods include a combination of hot rolling and warm rolling processes that reduce the thickness of the input material and increase its ductility. The resulting MMC strip can be coiled, which is useful for high volume coil-to-coil applications.Type: GrantFiled: May 6, 2019Date of Patent: May 14, 2024Assignee: Materion CorporationInventors: Karl R. Ziegler, Fritz Grensing, Jeffrey R. Campbell, Todd S. Osborn, Thomas F. Sirgey

Patent number: 11827569Abstract: A process of synthesizing a yttrium aluminum garnet (YAG) powder. The process comprises introducing powders of yttria and silica to form a powder mixture, wherein alumina is not added to the powder mixture. Milling the powder mixture in the presence of an alumina grinding media and a solvent forms a powder slurry. Processing the powder slurry forms a green compact. Calcining the green compact at a temperature of from 1100° C. to 1650° C. for greater than 8 hours in air to 50% or less theoretical density forms a YAG compact of at least 92 wt % Y3Al5O12. Milling the YAG compact, without a grinding media, and drying produces the YAG powder. Processes further include introducing a dopant to the powder mixture to produce doped YAG powder.Type: GrantFiled: January 28, 2022Date of Patent: November 28, 2023Assignee: Materion CorporationInventors: Sekyung Chang, Mario E. Cota, Robert E. Kusner, Fritz Grensing

Publication number: 20220220920Abstract: The present disclosure relates to piston assembly comprising a piston having a circumferential groove and a ring groove insert within the circumferential groove of the piston. Particularly, the ring groove insert is a second material different from a first material of the piston. The second material has at least one of the following: a) a density from 90% to 120% of a density of the first material; b) a coefficient of thermal expansion (CTE) from 50% to 90% of a CTE of the first material; or c) a thermal conductivity greater than a thermal conductivity of the first material.Type: ApplicationFiled: January 7, 2022Publication date: July 14, 2022Applicant: MATERION CORPORATIONInventors: Andrew Tarrant, David TRICKER, Steffen MACK, David KRUS, Andrew RUZEK, Fritz GRENSING
