(A possible reference source where pictures of engineered components that are being heat treated using different processes is ). This should also cover chemical corrosion and the use of other metals to reduce the effects of corrosion. Practical activity: following a demonstration of the safe use of heat treatment processes in the workshop, learners could manufacture test samples in low carbon steel using different forms of heat treatment. This could be, for example simple strips, test specimens or imitation spanners, depending upon the test resources available within the centre. In addition to low carbon steel, other ferrous alloys could be used for comparison. Question and answer plenary: how are the different processes changing the ferrous metals, and how do learners expect this to change the properties? Learners will need to interpret the equilibrium diagram and to specific values for the heat treatment temperatures The suggested engineering context for the presentation is tooling or gears / power transmission systems. The manufacture of the test samples could also support or benefit from performance outcomes 1 and 5 in the Production and Manufacturing unit. The quantification of properties could link with Assessment outcomes 1 and 2 of the Mathematics for Engineers unit.
