Patent number: 6295309Abstract: A VAR process is conducted in an apparatus characterized by a crucible wall that provides a stable shelf anchor. The VAR apparatus includes a furnace chamber, a consumable electrode formed of a material to be remelted within the furnace chamber and a crucible within the furnace chamber. The crucible has a wall that forms a vessel to collect melt material from the consumable electrode. At least part of the wall is textured to provide area for mechanical stabilization of the shelf as the underside of the shelf melts and the upperside of the shelf forms. In a vacuum arc remelting process, a consumable electrode is loaded into a furnace chamber above a cooled crucible having a textured wall that forms a vessel to collect melt material from the consumable electrode. The process includes striking a direct electric current between the electrode and a bottom of the crucible to cause melting of material from a tip of the electrode. Melt material is collected from the tip in the crucible.Type: GrantFiled: August 31, 2000Date of Patent: September 25, 2001Assignee: General Electric CompanyInventors: Mark Gilbert Benz, Michael Francis Henry, William Thomas Carter, Jr., Bernard Patrick Bewlay

Patent number: 6059904Abstract: A method combining isothermal and high retained strain forging is described for Ni-base superalloys, particularly those which comprise a mixture of .gamma. and .gamma.' phases, and most particularly those which contain at least about 40 percent by volume of .gamma.'. The method permits the manufacture of forged articles having a fine grain size in the range of 20 .mu.m or less. The method comprises the selection of a fine-grained forging preform formed from a Ni-base superalloy, isothermal forging to develop the shape of the forged article, subsolvus forging to impart a sufficient level of retained strain to the forged article to promote subsequent recrystallization and avoid critical grain growth, and annealing to recrystallize the microstructure. The method permits the forging of relatively complex shapes and avoids the problem of critical grain growth. The method may also be used to produce location specific grain sizes and phase distributions within the forged article.Type: GrantFiled: May 23, 1997Date of Patent: May 9, 2000Assignee: General Electric CompanyInventors: Mark Gilbert Benz, Michael Francis Henry, Charles Philip Blankenship, Jr., Aldo Enrique Murut

Patent number: 5649280Abstract: A method of high retained strain forging is described for Ni-base superalloys, particularly those which comprise a mixture of .gamma. and .gamma.' phases, and most particularly those which contain at least about 30 percent by volume of .gamma.'. The method utilizes an extended subsolvus anneal to recrystallize essentially all of the superalloy and form a uniform, free grain size. Such alloys may also be given a supersolvus anneal to coarsen the grain size and redistribute the .gamma.'. The method permits the manufacture of forged articles having a fine grain size in the range of about ASTM 5-12 (5-60 .mu.m).Type: GrantFiled: January 2, 1996Date of Patent: July 15, 1997Assignee: General Electric CompanyInventors: Charles Philip Blankenship, Michael Francis Henry, Eric Scott Huron, John Michael Hyzak
