Overview

What is he best known for?

The fields of study C.J. McMahon is best known for:

Alloy
Nickel
Oxygen

A significant part of his Fracture (geology) research incorporates Brittle fracture and Cleavage (geology) studies. Cleavage (geology) and Fracture (geology) are frequently intertwined in his study. His study brings together the fields of Phosphorus and Metallurgy. C.J. McMahon connects Embrittlement with Corrosion in his study. C.J. McMahon incorporates Corrosion and Embrittlement in his research. Composite material is frequently linked to Carbide in his study. His research on Carbide often connects related areas such as Composite material. By researching both Intergranular corrosion and Austenite, C.J. McMahon produces research that crosses academic boundaries. Austenite connects with themes related to Microstructure in his study.

His most cited work include:

Initiation of cleavage in polycrystalline iron (385 citations)
Hydrogen-induced intergranular fracture of steels (240 citations)
A microscopic theory of brittle fracture in deformable solids: A relation between ideal work to fracture and plastic work (217 citations)

What are the main themes of his work throughout his whole career to date

His work on Metallurgy is being expanded to include thematically relevant topics such as Corrosion. Composite material is often connected to Fracture (geology) in his work. His study on Fracture (geology) is mostly dedicated to connecting different topics, such as Composite material. His Grain boundary research extends to the thematically linked field of Microstructure. His Grain boundary study frequently draws connections between adjacent fields such as Microstructure. He conducts interdisciplinary study in the fields of Intergranular corrosion and Intergranular fracture through his works. C.J. McMahon undertakes multidisciplinary investigations into Intergranular fracture and Intergranular corrosion in his work. His multidisciplinary approach integrates Alloy and Metallurgy in his work. His study on Organic chemistry is mostly dedicated to connecting different topics, such as Impurity.

C.J. McMahon most often published in these fields:

Metallurgy (72.66%)
Composite material (41.41%)
Embrittlement (39.06%)

What were the highlights of his more recent work (between 2010-2017)?

Internal medicine (62.50%)
Radiology (50.00%)
Surgery (50.00%)

In recent works C.J. McMahon was focusing on the following fields of study:

Internal medicine is closely attributed to Heart disease in his study. Much of his study explores Radiology relationship to Diffusion MRI. His Diffusion MRI study frequently intersects with other fields, such as Diffusion-Weighted Magnetic Resonance Imaging. His research is interdisciplinary, bridging the disciplines of Effective diffusion coefficient and Diffusion-Weighted Magnetic Resonance Imaging. His research on Effective diffusion coefficient frequently links to adjacent areas such as Radiology. His Surgery study frequently links to related topics such as Tears. Many of his studies on Tears apply to Surgery as well. He integrates many fields, such as Nuclear medicine and Magnetic resonance imaging, in his works. His study deals with a combination of Magnetic resonance imaging and Nuclear medicine.

Between 2010 and 2017, his most popular works were:

Predictive value of PI-RADS classification in MRI-directed transrectal ultrasound guided prostate biopsy (30 citations)
Mode of delivery in pregnancies complicated by major fetal congenital heart disease: a retrospective cohort study. (21 citations)
First reported use of drug-eluting bioabsorbable vascular scaffold in congenital heart disease (17 citations)
