suure mangaanisisaldusega austeniitteras, mille plastse deformatsiooni mehhanismideks on nii dislokatsioonide libisemine kui ka mehaaniline kahestumine (vt kahestumine, mehaaniline kahestumine)
Good to know
Terase suurepärased mehaanilised omadused toatemperatuuril - tõmbetugevus enam kui 1000 MPa ja katkevenivus kuni 90 % - baseeruvad märkimisväärsel kalestuvusel.
a class of austenitic high-manganese steels which can deform both by glide of individual dislocations and mechanical twinning (see: twinning, mechanical twinning)
Good to know
They have outstanding mechanical properties at room temperature combining high strength (ultimate tensile strength exceeding 1000 MPa) and ductility (elangation to failure up to 90 %) based on high work-hardening capacity.
