Huang, W., Luo, J., Henein, H., Jordan, J.

Purpose – This paper aims to evaluate the sulfide stress cracking (SSC) resistance of L80 casing steels with different alloying chemistries (e.g., Ti-B and Mn-Cr-Mo) by correlating the reduction in area ratio with the mechanical property, inclusion and carbide. Design/methodology/approach – SSC...

Surface nanobubbles are nanoscopic gaseous domains on immersed substrates which can survive for days. They were first speculated to exist about 20 years ago, based on stepwise features in force curves between two hydrophobic surfaces, eventually leading to the first atomic force microscopy (AFM)...

Henein, H.

The physicochemical properties, viscosity, density, and surface tension, are critical properties of liquid metals and alloys. These properties are needed for thermodynamics, solidification modelling, and materials properties databases. The discharge crucible method (DC) developed in 2003 has been...

Chatelier, C., Wiskel, J.B., Ivey, D.G., Henein, H.

Precipitates in thin-walled (11 mm) and thick-walled X70 (17 mm) microalloyed X70 pipe steel are characterized using Rietveld refinement (a.k.a. quantitative X-ray diffraction (QXRD)), inductively coupled plasma mass spectrometry (ICP), and energy-dispersive X-ray spectroscopy (EDX) analyses....

Champdoizeau, Q., Valloton, J., Henein, H.

A hypoeutectic Al–22.5 wt pctCu sample was processed using the Electro-Magnetic Levitator on board of the International Space Station within the frame of the European Space Agency projects NEQUISOL and THERMOLAB. In total, 21 cycles of melting and cooling were carried out, with the last cycle...

Experimental atomic force microscopy (AFM) images show the dried-in patterns from amino acid solutions which can be in the form of dots or networks. The three-dimensional lattice-gas Kinetic Monte Carlo (KMC) model is applied to simulate the formation of dot-like and network-like particle...

Gawor, S., Wiskel, J.B., Ivey, D.G., Liu, J., Henein, H.

A standard NACE hydrogen induced crack test was used to evaluate the resistance of two compositions of X70 steel (X70-X (Ca/S ratio of 2.5) and X70-B (Ca/S ratio of <0.5)) under severe (pH = 2.7 and 100% H2S) and mild (pH = 5.5 and 100% H2S) sour service conditions. An ultrasonic technique was...

Wiskel, J.B., Ma, J., Ivey, D.G., Henein, H.

Transverse tensile samples were extracted from the centreline position of three different compositions of uncoated thick walled microalloyed X70 UOE pipe at a location 180° from the weld. Aging heat treatments of 5, 15, and 25 minutes and temperatures of 175, 215, and 255°C were applied. Tensile...

Spinelli, J.E., Bogno, A.-A., Henein, H.

Hypereutectic Al-18wt.%Si alloy is widely used in automotive industry as a wear resistant alloy for engine components. However, in the last few years, this traditional composition is being considered for processing by different rapid solidification methods. Positive points include its low thermal...
