摘要: Regions of discontinuous precipitation have been observed in the interdendritic regions directionally solidified (DS) cast IN 738 LC (16 Cr, 8.5 Co, 1.7 Mo, 2.6 W, Ta, 0.9 Nb, 3.4 Al, Ti, 0.10 Zr, 0.01 B, 0.17 C). This phenomenon was studied because such coarse may a detrimental effect on high-temperature properties. After various heat treatments and etching, specimens were examined. Individual precipitates analyzed. Difference mechanical properties between untransformed demonstrated through microhardness measurements. (DLC)
