“…The highest yield strength (YS) values of RHPed HEA (maximum YS: 1437 MPa AlCoCrFeNi 2.1 ) are close to that of Fe-20 Cr-20 Ni steel (YS: 1428 MPa) 207 , austenitic stainless steel (YS: 1410 MPa) 206 , etc. The strength-ductility combination for many RHP HEA is also higher compared to microalloyed steel (PSD: 18.4 GPa × %) 201 , dual-phase steel (PSD: 11.2 GPa × %) 209 , and ferritic stainless steel (PSD: 16.8 GPa × %) 203 (Fig. 11).…”

“…with High-PerformanceMaterials Post-RHP The comparison of tensile mechanical properties at room temperature of HEA with highperformance materials after RHP is presented in Fig. 10 [201][202][203][204][205][206][207][208][209] . The best strength ductility combination (PSD) of RHPed HEA (maximum PSD of 60 GPa × % FeCoCrNiMn-1 at % C) is in the same range of TWIP steel (PSD: 58 GPa × %) 204 , TRIP steel (PSD: 51 GPa × %) 208 .…”

“…NiTi şekil hafızalı alaşımların, özellikle çekme gerilimi altında deformasyon lokalizasyonu (martenzit bant oluşumu ve büyümesi) sergilediği bilinmektedir [14][15][16]. Bu davranış, düşük alaşımlı ferritik çeliklerde [17] gözlemlenen tipik Lüders bant oluşumuna benzerliği ile Lüders benzeri makroskobik deformasyon modu olarak adlandırılabilmektedir [18][19][20]. Deformasyonun lokalize olması durumunda, malzemede meydana gelen lokal ve nominal gerinim ve gerilimler birbirlerine göre büyük farklılıklar gösterdiğinden, lokalize /heterojen deformasyon modunun [9] ve malzemenin deformasyon davranışına etkiyen parametrelerin (mikroyapı, tekstür, sıcaklık, deformasyon hızı vb.)…”

“…Gao et al [ 25 ] found that austenitic stainless steel exhibited Lüders‐like deformation at the beginning of the plastic domain, while they suggested that the stable propagation of Lüders strain in the localized region can be enhanced by deformation‐induced martensite. Moreover, Lu et al [ 26 ] found that the formation of the Cottrell atmosphere by the high‐temperature Laves phase precipitation was related to the Lüders‐like deformation in super ferritic stainless steel. However, the existing research does not link the formation of Lüders‐like deformation in stainless steel to the deformation‐induced martensite, Cottrell atmosphere, and other factors.…”
