Thermal memory effect in Mn(CoFe)Ge intermetallic compound
The temperature memory effect (TME) in MnCo0.97Fe0.03Ge shape memory alloy, fabricated as pellets via arc-melting, has been investigated once the martensite phase was stabilized at room temperature. The results revealed that TME appears during the reverse transformation of thermally induced martensi...

| Sumario: | The temperature memory effect (TME) in MnCo0.97Fe0.03Ge shape memory alloy, fabricated as pellets via arc-melting, has been investigated once the martensite phase was stabilized at room temperature. The results revealed that TME appears during the reverse transformation of thermally induced martensite after incomplete transformation cycling, spanning the entire interval between the austenite start and finish temperatures. Although the reverse transformation temperature range can be broadened by kinetic interruption, restoring the sample to its relaxed state requires the completion of the transformation up to higher temperatures. This necessity must be considered for practical potential uses of these alloys as shape memory applications. |
