Such measurements should be added to advance the field and align with VACUUM. You state that all the alloys were melted at about 720 ¡ãC in the vacuum furnace(ZG-0.0) and the argon gas was used to avoid oxidation. But there is no such confirmation or testing if improved vacuum conditions would result in improved alloys. Table 1 shows no data for O,C,N, H. |
