Unit of Competency | MSATCM304A - Interpret basic binary phase diagrams |
---|---|---|---|
Description | This unit covers the knowledge and skills needed to interpret phase diagrams and so predict the microstructures of binary alloys. | ||
Employability Skills | This unit contains employability skills. | ||
Learning Outcomes and Application | This unit 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. In a typical scenario, a metallurgical 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. | ||
Duration and Setting | X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting. |

Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package. | ||
Overview of assessment | The person will be able to interpret binary phase diagrams. Assessment may be by workplace project, case study or suitable alternative. | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | It is essential that competence is demonstrated in the ability to: recognise and use correct scientific terminology in regards to phase diagrams source phase diagrams and other reference material from internal or external sources use phase diagrams to interpret intermediate and final phase structures of binary alloys | |
Relationship to other units | This unit may be assessed concurrently with other relevant units. | |
Assessment method and context | Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the elements, performance criteria, skills and knowledge. A holistic approach should be taken to the assessment. Assessors should gather sufficient, fair, valid, reliable, authentic and current evidence from a range of sources. Sources of evidence may include direct observation, reports from supervisors, peers and colleagues, project work, samples, organisation records and questioning. Assessment should not require language, literacy or numeracy skills beyond those required for the unit. The assessee will have access to all techniques, procedures, information, resources and aids which would normally be available in the workplace. The method of assessment should be discussed and agreed with the assessee prior to the commencement of assessment. | |
Resource implications | This section should be read in conjunction with the range of variables for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required. |
Submission Requirements

Assessment Tasks
Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
This describes the essential skills and knowledge and their level, required for this unit. |
Required skills: |
produce a basic cooling phase diagram from supplied data estimate composition from the structure of a phase diagram predict structure from the composition from a phase diagram |
Required knowledge: |
Competency includes sufficient knowledge of: methods of construction of phase diagrams for binary alloys. the phase changes that occur in binary alloy systems as recorded by the appropriate phase diagrams. the equilibrium and non equilibrium cooling of binary alloys and the resulting microstructures in cast and heat treated material. |
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. | |
Codes of practice/standards | Where reference is made to industry codes of practice, and/or Australian/international standards, it is expected the latest version will be used. |
Scientific techniques and principles of cooling phase diagrams relate to | Equilibrium phase diagrams Non-equilibrium phase diagrams Effect of temperature and alloying elements on structural changes Structures of homogenous and cored dendrites Structures of columnar and equiaxed grains Eutectic, eutectoid and peritectic reactions |
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
