The effect of processing on properties is nicely illustrated by plotting process-trajectories onto material property charts, showing how properties evolve with alloying, blending, heat treatment, working, or foaming. The talk will show process-trajectory charts for metals, polymers and ceramics. The trajectory charts are difficult for students to make because they require data for the same material in various different states - the same alloy in different states of heat treatment, or the same polymer with different quantities of different fillers. To ease this process a new datatable is now available for the CES EduPack 2016 which provides sets of records that meet the necessary criteria, each chosen to illustrate how one or more processes influence properties. All the records have a complete Level 2 property listing allowing the effect of the process to be explored across the entire list.
