REPORT

La-W (Lanthanum-Tungsten) H. Okamoto

[2000Kri] assessed the La-W phase diagram using a regular solution model. Because the calculated liquid (miscibility gap) was asymmetric, there must have been a calculation error. Figure 1 shows the La-W phase diagram revised by the authors (private communication).
