Dear sudheer,

you can measure the shape memory effect in different ways.

1. Bend Test Method :

Prepare a sheet of 0.5/1 mm thickness from the prepared alloy using rolling machine. Bend the sheet around the mandrel, note down the bent angle and heat the deformed sheet above Austenite finish temperature + 15 degree Celsius for 1 min. Note down the recovery angle and calculate the shape recovery percentage.

2. Compression method :

Prepare a cylindrical rod of 10 mm dia and 30 mm height from the prepared alloy, compress it for the required strain and heat the deformed rod above Austenite finish temperature + 15 degree Celsius for 10 min and calculate the difference in the original, compressed and recovered heights of the specimen, then using the above calculate shape recovery.

All the Best

Sorry I have no alloy-memory research expertise. My work is in practical learning and teaching: see ‘Inside Teaching: How to Make a Difference for Every Learner and Teacher’ (Routledge, 2017).
