Abstract Phase transformation behavior of the constrained Fe--Mn--Si--Cr--Ni shape memory
alloy has been studied in detail through measuring the resistance and the recovery stress as afunction of temperature simultaneously during heating and cooling. On cooling, the recoverystress increases with lowering temperature. At the temperature that the recovery stress isgreater than the yield strength, plastic deformation will first take place. With the further decreaseof the temperature, the ε martensite will be induced by the recovery stress at the temperature thatthe recovery stress reaches to the critical stress for stress--inducedεmartensite. Below this temperature, the recovery stress decreases with loweringtemperature. The above plastic deformation and the εmartensitic transformation induced by the recovery stress drastically relaxthe recovery stress. The recovery stress equations during heating and cooling have beenestablished respectively. The design principle of compositions for Fe--Mn--Si--Cr--Ni shape memory alloys pip couplings has been put forward.
