  1. Heat Treatment Technologies for Cutting and Stamping Tools Belarussian National Technical University (BNTU) Physico-Technical Institute (PhTI), National Academy of Sciences of Belarus Dr. Alexander Shmatov2-5 December 2002,Lisbon

  2. Belarussian National Technical University (BNTU) • Established in 1920 • 10 faculties, 46 professions for training students • Teaching staff: 1727 (54 Professors, 721 Assistant Professors) • Research staff: 493 total (120 D.Sc, 350 Ph.D) • 46 research laboratories, such as: • Laboratory of hardening technologies • Laboratory for problems of steel parts hardening • Laboratory of plasma and laser technologies • Laboratory of materials science and casting technologies • Laboratory of new structural materials • Laboratory of plastic metal working

  3. Physico-Technical Institute (PhTI), National Academy of Sciences of Belarus • Established in 1931 • Staff: 350 total (3 Academicians, 10 D.Sc, 57 Ph.D) • 23 research departments and laboratories, such as: • Department of materials science, including laboratory of laser technologies • Department of thermokinetics, including laboratory of heat treatment of metals and alloys • Department of beam and plasma technologies • Department of plasticity, including laboratory of protective and decorative coatings • Department of film materials • Department of technological deformability

  4. Promising Research Projects • ISTC B-694 Development of cost-effective Chemical Thermo-cycling Treatment technologies of steel tools for attaining properties of Damask steel (combination of high hardness, strength and toughness) Technological Projects • Strengthening thermo-cycling heat treatment process for tools made from high-speed steels (HSS) • Strengthening thermo-cycling heat treatment process for impact stamp tools Main idea of the Projects To increase the service durability of complex-shaped cutting and impact stamptools using conventional heat treatingequipment, cheap and ecologically safe ingredients by changing only the schedule ofheat treatment operations and composition of chemical active media.

  7. Advantages over known heat treatments The proposed process: • Increases bending strength of steelsby 10-35%; • Improves impact strength of steels by the factor of 1.5-15; • Enhances surface hardness by HRC 1-3 (up to HRC 67-70); • Is most efficient for tools experiencing high impact loads, especially thin, fine-sized and tools for rough machining; • Permits to improve productivity of tools by up to30%; • Can be used for processing materials with hardness HRC 40-45. • Processed tools can improve the surface finish by 1-2 level • Return-on-investment with new technologies will reachUSD1.5 to 7 per invested dollar

  8. Application of Technologies • The application of new technologies in industry requires minor expenses. • The cost of the operation increases by only 5-15% in comparison with standard heat treatments. • The technologies can be used on any enterprise having facilities for heat treatment and is easy to control. • The processed can be used for producing tools for: • Industry • Agriculture • Medicine • Metallurgy • Civil Engineering • Household

  9. Testing results Examples: the increase of service life of processed toolstimesItemSteel mills high-speed steels2 - 3 drills, broaches, reamershigh-speed steels1.5 - 2.5 screw taps, cuttershigh-speed steels1.5 - 4 punches die steel У8 (0.8% C) 2 - 10 threading dies 9XC (0.9% C, 1% Cr, 1.5% Si) 1.5 - 2 top dies, punches die steelX12 (2% C, 12% Cr) 2 - 3 • The process is used by several enterprises in Belarus and Russia.

  10.
