Unit 4009 Materials, Properties and Testing (J/615/1483) Assignment Brief 2026

University	Business and Technology Education Council ( BTEC)
Subject	Unit 4009 Materials Properties and Testing (J/615/1483)

Introduction

The world we live in would be a very different place without the sophisticated engineering materials currently available. Many of the things we take for granted, such as telecommunications, air travel, safe and low-cost energy, or modern homes, rely on advanced materials development for their very existence. Successful engineering application and innovation is dependent upon the appropriate use of these materials, and the understanding of their properties.

This unit introduces students to the atomic structure of materials and the way it affects the properties, physical nature and performance characteristics of common engineering/manufacturing materials; how these properties are tested, and modified by various processing treatments; and problems that occur which can cause materials to fail in service.

On successful completion of this unit students will be able to explain the relationship between the atomic structure and the properties of materials, translate design requirements into materials selection strategy and determine the suitability of engineering materials for use in a specified role using industry-standard software [GRANTA Edupack], explore the testing techniques to determine the properties of engineering materials and identify the causes of in-service material failure.

Learning Outcomes and Assessment Criteria

Pass	Merit	Distinction
LO1 Explain the relationship between the atomic structure and the different properties of materials		D1 Evaluate how the composition and structure of materials influence the properties of the parent material across the material’s range.
P1 Discuss, with example, the three crystal structures often found in metals. P2 Explain the different material properties that are associated with amorphous and crystalline polymer structures.	M1 Describe physical, mechanical, electrical and thermal material properties, choosing practical applications for each property if it were to be used in an engineering context.
LO2 Determine the suitability of engineering materials satisfying functional, environmental and sustainability requirements for use in a specified role		D2 Describe, with example, how to translate a product design specification into a material selection strategy and drive materials indices and select possible materials using the GRANTA Edu pack.
P3 Provide a list of the four materials categories, including an example of a product and application for each material identified. P4 Determine the specific characteristics related to the behaviour of the four categories of engineering materials.	M2 Explain how the behaviour of materials and circular economy needs to be considered when selecting a material for a given product or application. M3 Analyse, with examples, the effect heat treatment and mechanical processes have on material properties.
LO3 Analyse the testing techniques to determine the mechanical properties of an engineering material		D3 Critically evaluate sources of error in the mechanical test and make recommendations for better data collection.
P5 Analyse the results of mechanical test(s) on each of the four material categories in the form of a report.	M4 Compare results against industry-recognised data sources, explaining any difference found.
LO4 Investigate the causes of in-service material failure.		D4 Justify the methods that could be used for estimating product service life when a product is subject to creep and fatigue loading.
P6 Describe six common mechanisms of failure. P7 Investigate working and environmental conditions that lead to failure for a product made from material from each of the four material categories.	M5 Explain, with examples, the preventative measures that can be used to extend the service life of a given product within its working environment.
