Patent number: 10704125Abstract: A method of making a small diameter elongated steel article such as wire or strip is disclosed. The method includes the step of melting a steel alloy having the following weight percent composition C 0.88-1.00 Mn 0.20-0.80 Si 0.50 max. P 0.050 max. S 0.010-0.100 Cr 0.15-0.90 Ni 0.10-0.50 Mo 0.25 max. Cu 0.08-0.23 V 0.025-0.15? N 0.060 max. O 0.040 max. and the balance is iron and usual impurities. The method includes melting the alloy, atomizing the molten alloy to make a pre-alloyed metal powder, consolidating the metal powder to substantially full density, and then hot working the consolidated metal powder to form an intermediate elongated article. The method further includes a multi-step heat treating process. A small diameter, elongated steel article having enhanced machinability is also disclosed.Type: GrantFiled: November 9, 2016Date of Patent: July 7, 2020Assignee: CRS HOLDINGS, INC.Inventors: Olivier Schiess, Pierre Marechal, Gregory J.

Patent number: 4969944Abstract: The present invention is directed to a four-step process for molding glass articles of high precision and excellent surface figure. A glass preform having an overall geometry closely approximating that of the desired final product is placed into a mold, the mold and preform are brought to a temperature at which the glass exhibits a viscosity between 10.sup.8 -10.sup.12 poises, a load is applied to shape the glass into conformity with the mold, and thereafter the resulting glass article is removed from the mold at a temperature above the transformation range of the glass. The glass article is then annealed.Type: GrantFiled: December 4, 1989Date of Patent: November 13, 1990Assignee: Corning IncorporatedInventors: Jean-Pierre Marechal, Richard O. Maschmeyer
