High Temperature Behavior of Dual Phase Steels
Dual phase steels with different martensite volume fraction and morphology were tensile tested at a temperature range of 25 to 5500C. Stress-strain curves of all steels showed serration flow at temperatures of 250 and 3500C, and smooth flow at the other temperatures. Both yield and ultimate tensile strengths increased with increasing testing temperature up to about 450<sup...
متن کاملPhase transformation strengthening of high-temperature superalloys
Decades of research has been focused on improving the high-temperature properties of nickel-based superalloys, an essential class of materials used in the hot section of jet turbine engines, allowing increased engine efficiency and reduced CO2 emissions. Here we introduce a new 'phase-transformation strengthening' mechanism that resists high-temperature creep deformation in nickel-based superal...
متن کاملElectropulsing-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 کاملSuperconducting properties of copper oxide high - temperature
The equations for the magnon pairing theory of high-temperature copper-oxide-based superconductors are solved and used to calculate several properties, leading to results for specific heat and critical magnetic fields consistent with experimental results. In addition, the theory suggests an explanation of why there are two sets of transition temperatures (T, 90 K and Tc 55 K) for the YBa2Cu306+...
