Plastic deformation mechanisms that explain hot-rolling textures in Nickel–Titanium
Plastic deformation of B2 Nickel Titanium is usually attributed to { 110 } 〈 001 〉 slip and { 114 } 〈 221 〉 deformation twinning. The most commonly observed hot-worked texture of these alloys, is defined by a { 111 } 〈 u v w 〉 gamma fiber and { h k l } 〈 110 〉 partial alpha fiber. A Visco-Plasti...

The most commonly observed hot-worked texture of these alloys, is defined by a { 111 } 〈 u v w 〉 gamma fiber and { h k l } 〈 110 〉 partial alpha fiber. A Visco-Plastic Self Consistent (VPSC) model was used to establish relationships between microscopic slip and twin activity with the observed macroscopic hot-rolling texture. This knowledge will better aid in modeling NiTi austenite plasticity.

The relative CRSS ratios and hardening parameters were varied to study the effect of the deformation modes on the various texture components. Textures observed below 723 K and at less than 80% rolling reduction were simulated with deformation primarily accommodated on the { 110 } 〈 001 〉 slip mode and { 114 } 〈 221 〉 twinning mode.

Textures observed below 723 K and at less than 80% rolling reduction were simulated with deformation primarily accommodated on the { 110 } 〈 001 〉 slip mode and { 114 } 〈 221 〉 twinning mode. Textures observed at temperatures greater than 903 K and greater than 80% rolling reductions were captured in the simulations that included all three deformation modes. Activity on the { 100 } 〈 001 〉 slip mode strongly correlated with the { 110 } 〈 110 〉 texture component observed at high temperatures.</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">CRSS</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Hot-rolling</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Nickel–Titanium</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Visco Plastic Self Consistent</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Texture</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Stebner, Aaron P.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Rollett, Anthony D.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="n">Pergamon Press</subfield><subfield code="a">Noh, Ji Yun ELSEVIER</subfield><subfield code="t">Safe hospital preparedness in the era of COVID-19: The Swiss cheese model</subfield><subfield code="d">2020</subfield><subfield code="g">New York, NY</subfield><subfield code="w">(DE-627)ELV004621883</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:153</subfield><subfield code="g">year:2022</subfield><subfield code="g">pages:0</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.1016/j.ijplas.2022.103257</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ELV</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_U</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">44.75</subfield><subfield code="j">Infektionskrankheiten</subfield><subfield code="j">parasitäre Krankheiten</subfield><subfield code="x">Medizin</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">153</subfield><subfield code="j">2022</subfield><subfield code="h">0</subfield></datafield></record></collection>
