Magnetic field induced martensite

Magnetic field induced martensite

Magnetic field induced martensite

I am not a metallurgist, so please be easy with the terms. I have a question; is magnetic field induced martensite, and strain induced martensite, different terms for the same process?  Thanks,  Gerald

RE: Magnetic field induced martensite

Whoa!! Heavy stuff but I think they answer your question.
It appears that they are not the same, the magnetic field induced transformation seems to be a reversible phenomenon in some shape memory alloys and only exists while the field is applied.Stain induced transformation is however not reversible and can occur in more conventional alloys.

RE: Magnetic field induced martensite

As a side note to magnetic fields, I found this interesting technical presentation by our friends at Oak Ridge on the topic of "Ultrahigh Magnetic Field Processing of Materials for Developing Customized Microstructures and Enhanced Performance"


RE: Magnetic field induced martensite

Much obliged, metenger!

I just discovered this topic, so I have a lot of reading to do.  Thanks again,  Jerry

RE: Magnetic field induced martensite

As meteng pointed out, there can be a transformation from austenite to martensite induced by applying a magnetic field which reverses with the removal of the field. The strain induced transformation requires significant plastic deformation and remains after the stress which imposed the strain is removed.

RE: Magnetic field induced martensite

I learnt something new. Though this was vaguely  in my memory that one transformation is reversible while the other is not. Great posting and equally good responses.

For more reading on the subject, the following link gives some practial applications of strain induced martensite:
