Description
This unit of competency defines the knowledge and skills required to interpret phase diagrams and so predict the microstructures of binary alloys.It applies to the interpretation of cooling phase diagrams as used in metallurgy. The application will primarily be to phase diagrams of metals and alloys showing temperature and composition variables.It applies where a technician will be required to recommend a phase transition process in order to obtain a required microstructure, or to predict a microstructure from a known phase transition process.No licensing, legislative or certification requirements apply to this unit at the time of publication.Unit Weight: 4
Notes
Elements and Performance Criteria
1. Determine job requirements
  • 1.1 Follow standard operating procedures (SOPs)
  • 1.2 Comply with work health and safety (WHS) requirements at all times
  • 1.3 Identify job requirements from work information
2. Identify the microstructures from an equilibrium cooling phase diagram
  • 2.1 Obtain phase diagram for metal or alloy from internal or external sources
  • 2.2 Identify number, composition, proportion and structural arrangement of phases in binary alloys
  • 2.3 Identify structural changes due to varying proportion of alloying elements and temperature
  • 2.4 Identify the phase changes and final microstructures of binary alloys cooled under equilibrium conditions from the melt or during heat treatment operations
3. Identify the microstructures from a non-equilibrium cooling phase diagram
  • 3.1 Identify number, composition, proportion and structural arrangement of phases in binary alloys
  • 3.2 Identify structural changes due to varying proportion of alloying elements and temperature
  • 3.3 Identify the phase changes and final microstructures of binary alloys cooled under equilibrium conditions from the melt or during heat treatment operations
4. Recognise characteristic microstructures of binary alloys
  • 4.1 Recognise characteristic structures of dendrites (homogeneous and cored) columnar and equiaxed grains
  • 4.2 Recognise characteristic structures resulting from eutectic, eutectoid and peritectic reactions
  • 4.3 Recognise characteristic structures resulting from solid state precipitation
