Abstract

MAFFIA, Ernesto G; TOVIO, Daniel; COZZARIN, Ana L  and  GONZALEZ, Alfredo. Effects of Homogenization Treatment on the Workability of Alloy CuNiSiCr. Inf. tecnol. [online]. 2010, vol.21, n.5, pp.51-60. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642010000500008.

In order to improve the workability of alloys CuNiSiCr a study of the conditions of homogenizing heat treatment and assessed their behavior through mechanical tests traction. Standardized tests were conducted at 850, 950 and 1025°C with time-keeping 0, 1.5 and 6 hours and a subsequent double aged. It was observed that the optimum workability for the alloys occurs at the 850°C and 6 hours. This improvement in ductility is associated with the presence of a microstructure containing a small amount of discontinuous precipitates in limiting grain and rounded precipitates inside the grains. It is concluded that the homogenizing heat treatment is and adequate method to increase the workability of the alloy.

Keywords : CuNiSiCr alloy; thermal treatment; homogenization; grain growth; ductility.
