Lp. Zhang et al., THE ISOTHERMAL SECTION OF THE CU-RICH CU-BE-CR (LESS-THAN-OR-EQUAL-TO-50-AT.PERCENT-BE) TERNARY-SYSTEM AT 500-DEGREES-C, Zeitschrift fur Metallkunde, 86(11), 1995, pp. 774-775
The isothermal section of the phase diagram of the Cu-Be-Cr (less than
or equal to 50 at.% Be) ternary system at 500 degrees C has been inve
stigated by X-ray powder diffraction. The isothermal section consists
of three single-phase regions (a-Cu, Cr and CuBe), three two-phase reg
ions (alpha-Cu+Cr,Cu+CuBe and CuBe+alpha-Cu) and one three-phase regio
n (alpha-Cu+ Cr+CuBe). The maximum solubility of Be in alpha-Cu is abo
ut 6.6 at.%.
