This work is a preliminary examination of mechanistic issues on the comparative corrosion performance of regular epoxy-coated rebar (ECR) and dual polymer-zinc coated reinforcement (DCR) in simulated concrete pore solution with and without chloride ions, at polarizations from +100 mV to -1000 mV in the saturated calomel electrode (SCE) scale and exposure periods of 1 month or longer. Both mater...

We present recent work on a dual probe system containing electromagnetic acoustic transducers (EMATs) generating and detecting surface ultrasonic waves, and a pulsed eddy current (PEC) probe. This system is able to detect and size surface and near-surface defects in electrically conducting samples by looking at changes in the detected signal for each probe. By combining the information from eac...

Acetabular fractures are quite challenging injuries for the orthopedic surgeon due to low incidence and the deep and complex anatomy. A 61 y old man fell from a single-storey house and sustained a right acetabular fracture and cartilage wear. The dual-column was fixed with cannulated screw fixation via anterior ilioinguinal approach and received second surgery of open reduction and pelvic recon...

Effects of vanadium (V) addition on strain distribution, crack initiation and propagation behavior during low-cycle fatigue test in ferrite martensite dual phase (DP) steel were revealed. V effectively extended the life, even though tensile properties approximately identical between V-added DP steels. The stress amplitude suddenly decreased just before fracture steel. initiated from surface pro...

The effect of the initial microstructure and intercritical annealing on mechanical properties and work-hardening response of a high-formability low carbon steel were studied. The work-hardening analysis was based on the modified Crussard–Jaoul method. The ferritic-pearlitic sheets showed low strength and high total elongation with the appearance of the yield point phenomenon. The occurrence of ...
