The　phase　transformation　hypocrisy-elasticity　behaviour　and　the　shape　memory　completeness　of　four　Fe-Mn-Si-Ni-Cr　alloys　deformed　at　different　temperatures　are　reported.　An　incomplete　phase　transformation　hypocrisy-elasticity　caused　by　the　gamma--＞epsilon　martensite　reversible　transformation　is　exhibited　in　an　Fe-14Mn-5Si-9Cr-5Ni　alloy　at　473　K.　The　shape　recovery　completeness　of　four　alloys　depends　on　the　difference　between　M-d　and　M-epsilons,　T-N　temperatures　and　the　stacking　fault　energy　of　the　parent　phase.　It　is　practically　meaningful　that　a　quite　high　net　recovery　strain　can　be　obtained　in　Alloys　2　and　4　by　the　addition　of　the　rare　earth　Cerium　and　Nitrogen　elements　when　pre-strained　at　300　and　77　K,　respectively.　The　net　recovery　strain　is　4.3%　in　Alloy　2　and　4.6%　in　Alloy　4,　respectively,　at　pre-strain　5.3%.　(C)　2002　Elsevier　Science　B.V.　All　rights　reserved.
