Nano-(Ta, Zr)C Precipitates at Multigrain Conjunctions in TaC Ceramic with 10 mol% ZrC and 5 mol% Cu as Sintering Aid

Figure 3

TEM of the consolidated TaC ceramic with 10 mol% ZrC plus 5 mol% Cu as sintering aid (a). EDS (b) and DP (c) evidenced metallic Cu. And again (d) ring DP showed polycrystalline nano-(Ta, Zr)C in neighbor of Cu and (e) DP of the circled (Ta, Zr)C grain.
