Microalloyed steels are widely used in oil and gas pipelines. They are a class of high strength, low carbon steels containing small additions (in amounts less than 0.1 wt%) of Nb, Ti and/or V. The steels may contain other alloying elements, such as Mo, in amounts exceeding 0.1wt%. Microalloyed...

Solidification during continuous casting of X70 microalloyed steel results in two types of elemental segregation; microsegregation (interdendritic) and macrosegregation (at the centerline). Both micro and macrosegregation lead to deterioration of steel properties and, hence, a lower degree of...

Four alloys were studied to observe the effects of Rapid Solidification and alloying on the morphology of a hypereutectic Al-40Si. Impulse Atomization was used to produce the samples studied. This processing technique was used to attain high undercoolings and liquid cooling rates ranging 103-105...

Sulfide Stress Cracking Susceptibility of Low Alloy Steels for Casing Application in Sour Environments
DownloadFall 2012
Sulfide stress cracking (SSC) resistance of casing steels with different alloying chemistries (i.e. Ti-B and Mn-Cr-Mo) was evaluated using constant load tensile test and slow strain rate test in NACE-TM0177 environment. SSC resistance in terms of RAH2S/RAair and time to failure was found to...

The Microstructure, Morphology and Mechanical Properties of Rapidly Solidified Al-10wt%Si Alloy
DownloadSpring 2018
Hypoeutectic Al-Si alloys are widely used in both the automotive and aerospace industries, due to their strong corrosion resistance, good castability and relatively high strength-to-weight ratio. Despite this wide use, these alloys have a major limitation related to the Si phase that forms...

Thermophysical Properties Measurement of Liquid Al and Al-Cu by the Discharge Crucible Method
DownloadFall 2020
The demand to develop Materials Genomics and Integrated Materials Computation requires the availability of high temperature property data of liquid metals. High temperature metallurgical processes, such as refining, casting, welding and additive manufacturing, can be optimized and operate more...
