Electropulsing-induced steels strengthening at high temperature
Electropulsing usually reduces the stability of metastable phases in materials. This work reports the opposite effect, where electropulsing drives the stable -phase at high temperature to be decomposed. This enables both γ-phase and σ-phase in duplex stainless steel to survive and hence to strengthen the steel at high temperature. The hardness of the quenched sample after electropulsing is 49....
متن کاملDislocation Strengthening without Ductility Trade-off in Metastable Austenitic Steels
Strength and ductility are mutually exclusive if they are manifested as consequence of the coupling between strengthening and toughening mechanisms. One notable example is dislocation strengthening in metals, which invariably leads to reduced ductility. However, this trend is averted in metastable austenitic steels. A one-step thermal mechanical treatment (TMT), i.e. hot rolling, can effectivel...
متن کاملComparison of Mechanical Behavior and Microstructure of Continuous Cast and Hot Worked CuZn40Al1 Alloy (TECHNICAL NOTE)
The performance of components produced by conventional route of a thermo mechanical process and those produced by continuous casting is interesting from different aspects of economy and technology. The performance of products in their service depends on their properties which are strongly influenced by production routes. In the present work the hardness, tensile and tensile-impact behaviors of ...
متن کاملMicrostructure Evolution of HSLA Pipeline Steels after Hot Uniaxial Compression
The mechanical properties of the high-strength low-alloy pipeline steels were mainly controlled by the subsequent phase transformations after rolling. The influence of hot uniaxial compression on the phase transformation of acicular ferrite was explored by viewing of the deformation degree, the deformation temperature, and the strain rate. The results show that the increase of deformation amoun...
متن کاملStudy on Oxidation of Stainless Steels During Hot Rolling
The oxidation of stainless steels 304 and 304L during hot rolling is studied in this paper. Results show the oxide scale thickness decreases significantly with an increase of reduction, and the oxide scales of both 304 and 304L stainless steels were found more deformable than the steel substrate. Surface roughness shows a complicated transfer during the hot rolling process due to the complexity...
