EFFECT OF SILICON CONTENT ON THE STRAIN HARDENING OF DUAL-PHASE STEELS
Abstract: In the current work, the strain hardening behavior of dual-phase steels with different silicon content (0.34- 2.26 Wt. %) was examined using the modified Crussard-Jaoul analysis. It was shown that these dual-phase steels deform in two stages over a uniform strain range. Each stage exhibited a different strain hardening exponent varying with silicon content. At the first stage, work...
متن کاملElectric Current Induced Thermomechanical Fatigue Testing of Interconnects
We demonstrate the use of electrical methods for evaluating the thermomechanical fatigue properties of patterned aluminum and copper interconnects on silicon-based substrates. Through a careful selection of alternating current frequency and current density, we used controlled Joule heating to simulate in an accelerated manner the type of low frequency thermal stress cycles that an interconnect ...
متن کاملThe Effect of Ferrite Grain Size on the Fatigue Behavior of Ferrite-martensite Dual-phase Steels
The effect of ferrite grain size on the fatigue and tensile properties of dual phase steels with a 0.25 volume fraction of martensite (Vm) under different heat treatments was investigated. The heat treatments were homogenized at 1200 oC along with several subsequent normalizations at 910 oC, resulting in different microstructures and mechanical properties. After heat treatment, the obtained ste...
متن کاملDamage evolution in compacted graphite iron during thermomechanical fatigue testing
Thermomechanical fatigue properties of a compacted graphite iron in an out of phase configuration are investigated for different maximum temperatures and mechanical strain ranges. Furthermore, the stress-strain hysteresis loops are analysed and in particular the unloading modulus, i.e. the elastic modulus measured during specimen unloading, is obtained from each cycle. This material parameter h...
متن کاملDuplex Hardening of Steels for Aeroengine Bearings
Duplex hardening is a process in which conventional heat-treatments such as secondary or case hardening are followed up by surface nitriding to achieve exceptional properties, particularly in the context of aeroengine bearings. Hardness values in excess of 1 000 HV can in principle be achieved, and although the hardness decreases as a function of depth below the surface, some level of enhanceme...
