Hot working analysis of a CuZn40Pb2 brass on the monophasic (beta) and intercritical (alpha plus beta) regions

The high temperature deformation behavior of a Cu4OZn2Pb brass was studied by means of compression and tensile tests in the beta monophasic and alpha/beta biphasic regions. The ductility evaluated in terms of elongation and area reduction allowed to distinguish three regions: one 13 monophasic regio...

Descripción
Sumario:The high temperature deformation behavior of a Cu4OZn2Pb brass was studied by means of compression and tensile tests in the beta monophasic and alpha/beta biphasic regions. The ductility evaluated in terms of elongation and area reduction allowed to distinguish three regions: one 13 monophasic region (above 720 degrees C), and two alpha/beta biphasic regions, between 720 degrees C and 600 degrees C, and below 600 degrees C. The fracture appearance was evolving from a ductile type, with dimple formation, to a more brittle one with grain decohesion as the deformation temperature was decreased or the amount of 13 phase reduced.; The
