4180398 Modification of leaded brasses to improve hot workability December 25, 1979
Leaded brasses are modified by additions of chromium, antimony and bismuth in order to reduce the susceptibility of the brasses to edge cracking during hot working. The additional alloying elements also help to maintain the widely known good machinability characteristics of the leaded br
4148633 Minimization of edge cracking during hot rolling of silicon-tin bronzes April 10, 1979
Particular copper base alloys consisting essentially of silicon, tin and mischmetal are disclosed which exhibit improved resistance to edge cracking during hot working operations. Various other elements such as chromium, manganese, iron and nickel may also be added to the alloy to in
4110132 Improved copper base alloys August 29, 1978
The instant disclosure teaches a process for obtaining an improved combination of strength and bend properties in copper base alloys having low stacking fault energy. The process is characterized by a critical combination of cold reduction and annealing following recrystallization. I
4047978 Processing copper base alloys September 13, 1977
The instant disclosure teaches a process for obtaining an improved combination of strength and bend properties in copper base alloys having low stacking fault energy. The process is characterized by a critical combination of cold reduction and annealing following recrystallization.
4025367 Process for treating copper alloys to improve thermal stability May 24, 1977
A process for improving the thermal stability of copper alloys having a low stacking fault energy is disclosed which comprises cold working the alloy, heating the alloy at a first temperature of from 100.degree. to 300.degree. C, additionally heating the alloy at a second temperature of
3956027 Processing copper base alloys May 11, 1976
A process for obtaining improved bend properties in copper base alloys with retention of other desirable characteristics thereof. The process is characterized by a final cold reduction with a large number of passes coupled with a small reduction per pass.
