Module content
Lectures (28h):

Basic definitions (metallic glasses, bulk metallic glasses, nanometerials, critical cooling rate, critical diameter). History of metallic glasses. Thermodynamic and kinetic aspects of glass transition. Glass-forming ability. Freezing diagrams. Synthesis of metallic glasses and bulk metallic glasses (splat quenching, melt spinning, ejection casting, suction casting, tilt casting). Crystallization of metallic glasses. Amorphous-crystalline materials. Physical and mechanical properties of bulk metallic glasses and amorphous-crystalline composites.

Laboratory classes (14h):

1. Synthesis of Fe-based and Zr-based metallic alloys for further laboratory exercises by arc melting of high purity elements under Ti-gettered argon atmosphere.
2. Synthesis of Fe-based metallic glasses by melt spinning method using different spinning conditions (wheel speed, ejection pressure, ejection temperature).
3. Synthesis of Zr-based glass-forming alloy by arc melting and suction casting using different casting conditions (melting current, rod diameter).
4. Estimation of cooling rate in suction casting process based on microstructural features in the Fe-25Ni suction-cast alloy (measurement of cellular dendrites spacing).
5. DSC analysis of melt-spun Fe-based and Zr-based sution-cast alloys. Determination of glass-forming ability.
6. Mechanical properies of metallic glasses and amorphous-crystalline composites.
Compression testing of Zr-based bulk metallic glasses bulk metallic glass matrix composites.
7. Effect of oxygen content on the glass-forming ability.
Oxygen analysis of the Zr-based alloys synthesised using Zr of different purities by inert gas fusion method. Relation between glass-forming ability and oxygen level.

Teaching methods and techniques:
  • Lectures: Treści prezentowane na wykładzie są przekazywane w formie prezentacji multimedialnej w połączeniu z klasycznym wykładem tablicowym wzbogaconymi o pokazy odnoszące się do prezentowanych zagadnień.
  • Laboratory classes: W trakcie zajęć laboratoryjnych studenci samodzielnie rozwiązują zadany problem praktyczny, dobierając odpowiednie narzędzia. Prowadzący stymuluje grupę do refleksji nad problemem, tak by otrzymane wyniki miały wysoką wartość merytoryczną.
Warunki i sposób zaliczenia poszczególnych form zajęć, w tym zasady zaliczeń poprawkowych, a także warunki dopuszczenia do egzaminu:

Podaje Prowadzący na pierwszych zajęciach w semestrze

Participation rules in classes:
  • Lectures:
    – Attendance is mandatory: No
    – Participation rules in classes: Studenci uczestniczą w zajęciach poznając kolejne treści nauczania zgodnie z syllabusem przedmiotu. Studenci winni na bieżąco zadawać pytania i wyjaśniać wątpliwości. Rejestracja audiowizualna wykładu wymaga zgody prowadzącego.
  • Laboratory classes:
    – Attendance is mandatory: Yes
    – Participation rules in classes: Studenci wykonują ćwiczenia laboratoryjne zgodnie z materiałami udostępnionymi przez prowadzącego. Student jest zobowiązany do przygotowania się w przedmiocie wykonywanego ćwiczenia, co może zostać zweryfikowane kolokwium w formie ustnej lub pisemnej. Zaliczenie zajęć odbywa się na podstawie zaprezentowania rozwiązania postawionego problemu.
Method of calculating the final grade:

Ocena końcowa obliczana jest jako średnia z ćwiczeń laboratoryjnych
