Can I work with shape memory materials at home?

Question

Do it yourself

Tell me, please:
0) Do I understand correctly that a shape memory material (SMF) remembers its shape at a certain, sufficiently high temperature?
1) Are there shape-memory MSFs (I think it's called the austenitic phase) at temperatures that are effortlessly achievable at home? Preferably a burner, not a blowtorch.
2) And if so, how much does it cost and where can I get it? You need wire.
If I've misunderstood something somewhere, please correct me. In general, the task is to give the wire a shape so that when heated, it restores this original shape.

Answer 1

For example, on ebay there is a lot of titanium nickelide. Works depending on:
composition
If you go through the chinanet (shape memory effect), then I think you can find it cheaper.
In short - you can work, specific equipment, in theory, is not required.

Answer 2

0) Here it is necessary to look at the zone of existence of the reverse martensitic transformation. It is necessary to give a shape above this temperature. For modern SME materials, these are very low temperatures. Well, the zone of direct M transformation and give shape below this zone. (These are temperature zones).
1) Naturally. For modern materials, these are tens and hundreds of degrees. (Initial hundreds). Another thing is that in the corresponding material, you first need to harden it to martensite.
Why didn't you read the wiki article. It's pretty well written. And the literature on the topic is given.
