This research consisted in comparing the fatigue crack growth (FCG) performance of four HSLA/ AHSS steels used automotive applications and with different microstructures, application some prediction models for da/dN versus ΔK traditional sigmoidal curve as a function R load ratio. FCG tests were carried out on C(T) test specimens R-ratios varying between 0.03 0.7. Using original empirical meth...

The objective of this research work is to obtain the hot ductility behavior, and structural, microstructural mechanical characteristics one latest generation AHSS steels, a complex phase (CP) steel microalloyed with boron (0.006 wt.%), processed by cold rolling operations heat-treated using two different quenching partitioning (Q&P) treatments, one-step (quenching 420 °C) other two-step °C ...

Twinning-induced plasticity (TWIP) steels have higher strength and ductility than conventional steels. Deformation mechanisms producing twins that prevent gliding stacking of dislocations cause a steel grades with the same strength. TWIP are considered to be within new generation advanced high-strength (AHSS). However, some aspects, such as corrosion resistance performance in service materials,...

Steels applied in the automotive industry can be classified under the AHSS category, which includes dual-phase (DP) steels, complex-phase (CP) steels and transformation-induced plasticity (TRIP) steels. The UHSS category mainly includes martensitic steels. The above-mentioned steel groups are well pressable, show an excellent combination of strength, service life and absorption of strain energy...

INTRODUCTION In Australia, Home Medicines Review (HMR) has been found to be an important tool to raise awareness of medication safety, reduce adverse events and improve medication adherence. Aboriginal and Torres Strait Islander people are 'underserviced' by the HMR program and are the most likely of all Australians to miss out on HMRs despite their high burden of chronic disease and high rates...

With the increasingly demanding schedules of formal and casual learners and the proliferation of terminal devices available for content delivery, learners are demanding ubiquitous access to their learning. The multi-modal nature of the variety of devices employed by these learners will necessitate that learning experiences can be started on one device and transitioned seamlessly to another as t...

The challenges facing the health of communities around the world are unprecedented, and the data are all too familiar. For 5 billion people living in developing countries, environmental factors and inadequacies in hygiene, economic development, and health-care access are the main causes of shortened life expectancies. Improvements in health status, including reductions in infant mortality and d...

Vehicle weight reduction, reduced costs and improved safety performance are the main driving forces behind material selection for automotive applications. These goals are conflicting in nature and solutions will be realized by innovative design, advanced material processing and advanced materials. Advanced high strength steels are engineered materials that provide a remarkable combination of fo...
