  2. The Five Steps: • Solidus Line • Liquidus Line • Sub-Liquidus Line • Alchemades Line Intersections • Labels Click to continue

  3. ZrO2 ZrTiO4 1610° 1590° 1580° TiO2 Al2O3 Al2TiO5 Diagram Construction: • Identify primary phase fields • Draw Alchemades lines • Identify direction of falling temperature on boundary lines. ZrO2 ZrTiO4 Al2O3 TiO2 Al2TiO5 Click to continue

  4. ZrO2 ZrTiO4 ZrO2 Section Line 1610° 1590° c ZrTiO4 cc 1580° Al2O3 TiO2 Al2TiO5 TiO2 c cc Al2O3 Al2TiO5 Set-up • Choose the Section Line (c - cc). • Draw diagram framework. Click to continue

  5. ZrO2 ZrTiO4 ZrO2 1610° 1590° c ZrTiO4 cc 1580° 1610° Al2O3 1590° TiO2 1580° Al2TiO5 c cc TiO2 Al2O3 Al2TiO5 Step 1 - Solidus lines • Which compatibility triangles are crossed? • Find the associated ternary invariant points. • Indicate temperatures on (c - cc) diagram. • Draw Solidus lines on (c - cc) diagram. 1610° 1590° 1580° Click to continue

  6. ZrO2 ZrTiO4 ZrO2 1610° 1590° c ZrTiO4 cc 1580° 1610° Al2O3 1590° TiO2 1580° Al2TiO5 c cc TiO2 Al2O3 Al2TiO5 Step 2 - Liquidus line • The top view of the liquidus line can be seen on the ternary diagram. • Find the end points and points where the liquidus line crosses any boundary lines. • Estimate and plot relative temperatures of these points. • Draw liquidus line - estimate curvature.

  7. ZrO2 ZrTiO4 ZrO2 1610° 1590° c ZrTiO4 cc 1580° 1610° Al2O3 1590° TiO2 1580° Al2TiO5 c cc TiO2 Al2O3 Al2TiO5 Step 3 - Sub-Liquidus line What are “critical” compositions? • Find and indicate all of the “critical” compositions. • Perform isoplethal analysis - record temperature where boundary line is intersected. • Draw sub-liquidus line. • Check each segment with an intermediate isoplethal analysis. Click to continue
