Effect of the morphology of the martensite-austenite phase on fracture of the weld heat affected zone in vanadium and niobium microalloyed steels [PDF]
In multipass welding, the intercritically reheated coarse grained heat affected zone demonstrates the worst toughness in welded joint, since it contains a high-carbon martensite with some retained austenite, known as M-A phase, which is brittle and ...

The effect of ceria co-doping on chemical stability and fracture toughness of Y-TZP [PDF]
The fracture toughness and ageing resistance of yttria, ceria-stabilized tetragonal zirconia polycrystals (Y, Ce-TZP) were evaluated as a function of grain size and ceria content.

Impact modification of poly(caprolactam) by copolymerization with a low molecular weight polybutadiene [PDF]
Caprolactam and a reactive, low molecular weight polybutadiene were polymerized in an autoclave, followed by post-condensation in the solid state. The rubber concentration was varied (0–30 wt%).

Low temperature tensile properties of line pipe steels [PDF]
Given the expected increase in Arctic oil and gas exploitation, there is a demand for high-strength line pipe steels able to cope with the Arctic climate. The state-of-the-art of the tensile properties of API 5L steels at low temperatures is reviewed and

Influence of boron content on the fracture toughness and fatigue crack propagation kinetics of bainitic steels [PDF]
The relatively good combination of high strength and ductility makes bainitic steels a candidate to replace many other steels in industrial applications. However, in service, ductility and strength are not up to standard requirements.
