Learning outcomes

On successful completion of

this unit a learner will:

Assessment criteria for pass

The learner can:

 

LO1 Be able to determine the

properties and selection

criteria of materials from

tests and data sources

 

1.1 detail the appropriate properties and criteria for the

selection of a metallic, ceramic, polymer and composite

material

1.2 explain the particular characteristics related to the

microstructure and macroscopic behaviour of the four

categories of engineering materials

1.3 generate and process test data to assess material

properties for two categories of material

1.4 investigate and assess the quality of suitable data from

three different sources

 

LO2 Understand the relationships

between manufacturing

processes and material

behaviour

 

2.1 explain how one heat treatment process and two other

treatment processes affect the structure, properties and

behaviour of the parent material

2.2 explain how one liquid processing method and two

mechanical processing methods affect the structure,

properties and behaviour of the parent material

2.3 investigate how the composition and structure of metal

alloys, polymers and polymer matrix composites

influence the properties of the parent material

 

LO3 Be able to select suitable

materials and processing

methods for a specific

product

 

3.1 analyse the function/s of a product in terms of the

materials’ constraints on its design

3.2 identify the required properties for the product and

select the most appropriate materials and processing

methods

3.3 identify and explain the possible limitations on the

product imposed by the processing and by the need to

safeguard the environment and minimise costs

 

LO4 Understand the in-service

causes of failure of

engineering materials

 

4.1 explain the common causes of in-service failure for

products or structures produced from each or a

combination of the four categories of engineering

materials

4.2 for one product or material structure, identify and

explain the in-service conditions that may contribute to

early failure

4.3 explain the methods for investigating materials failure

and for estimating product service life, when a product

is subject to creep and fatigue loading

4.4 determine and make recommendations for

remedial/preventive measures for a given product or

materials structure, that will help improve its service life.
