  1. NADCA - Die Materials Committee Meeting DIE MATERIALS FOR CRITICAL APPLICATIONS AND INCREASED PRODUCTION RATES John F. Wallace David Schwam Quanyou ZhouCase Western Reserve University Cleveland, OH - November 14, 2001

  2. OUTLINE 1. Shorter cycles - cooling curves in the biscuit. 2. Evaluation of non-ferrous alloys. 3. Results of recently tested die steels.

  3. INCREASING PRODUCTIVITY WITH SHORTER CYCLES • METHOD: • Utilize high thermal conductivity materials to extract heat faster from the large cross sections. EXPERIMENTAL • Shot blocks made of H13, Brush Alloy 3 (CuBe-based), • Brush MoldMax (CuBe-base), Brush MoldMax XL (copper-base) • CMW Anviloy (W), ALLVAC 718 (Ni-base), Nibryl (NiBe). • Record cooling curve of the biscuit. • Determine “Die Open” time for different shot block materials.

  4. Cooling Curve in the Biscuit with Anvilloy 1150 Shot Block

  5. Cooling Curve in the Biscuit with CuBe-C3 Shot Block

  6. TH13-Open=28.6(s) TAnvilloy 1150-Open=23.5(s) TMold XL-Open=20.0(s) TCuBe-3C-Open=18.2(s) TMold Ma-Open=18.0(s)

  7. H13 Anvilloy 3C CuBe

  8. Effect of Shot Block Material on Cooling Time of Biscuit Die Open” time (@950oF)for Brush Alloy 3C is 18.2 sec. vs. 28.6 sec. for H13. This is a 36% reduction in cycle time.
