Overview

What is he best known for?

The fields of study he is best known for:

  • Composite material
  • Thermodynamics
  • Metallurgy

Ahw Ngan spends much of his time researching Nanoindentation, Dislocation, Composite material, Crystallography and Plasticity. Nanoindentation is a subfield of Metallurgy that Ahw Ngan tackles. His Dislocation research incorporates themes from Integral transform, Compression, Nanopillar and Shear stress.

His research integrates issues of Copper, Resolution and Crystallite in his study of Composite material. In general Crystallography study, his work on Slip often relates to the realm of Molecular dynamics, thereby connecting several areas of interest. His Plasticity research includes themes of Numerical analysis, Classical mechanics and Integral equation.

His most cited work include:

  • Depth dependence of hardness in copper single crystals measured by nanoindentation (136 citations)
  • Breakdown of Schmid’s law in micropillars (94 citations)
  • Nanoindentation investigation on the mechanical stability of individual austenite grains in a medium-Mn transformation-induced plasticity steel (82 citations)

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

Nanoindentation, Composite material, Dislocation, Metallurgy and Condensed matter physics are his primary areas of study. The Nanoindentation study which covers Mechanics that intersects with Statistical mechanics and Granular material. His study looks at the intersection of Composite material and topics like Thin film with Nanocrystalline material.

His Dislocation research integrates issues from Stress, Nucleation, Forensic engineering and Plasticity. As part of the same scientific family, Ahw Ngan usually focuses on Condensed matter physics, concentrating on Slip and intersecting with Classical mechanics. The study incorporates disciplines such as Transmission electron microscopy and Grain size in addition to Crystallography.

He most often published in these fields:

  • Nanoindentation (30.86%)
  • Composite material (30.29%)
  • Dislocation (22.29%)

What were the highlights of his more recent work (between 2011-2019)?

  • Composite material (30.29%)
  • Dislocation (22.29%)
  • Nanoindentation (30.86%)

In recent papers he was focusing on the following fields of study:

Ahw Ngan mainly focuses on Composite material, Dislocation, Nanoindentation, Metallurgy and Crystallography. His study connects Thin film and Composite material. His work in the fields of Dislocation, such as Dislocation creep, overlaps with other areas such as Probability density function.

His Nanoindentation research includes elements of Transmission electron microscopy, Microscale chemistry and Elastic modulus. He focuses mostly in the field of Metallurgy, narrowing it down to topics relating to Porosity and, in certain cases, Diamond, Scratch, Asperity and Aluminium oxide. In general Crystallography, his work in Crystallite is often linked to Vimentin linking many areas of study.

Between 2011 and 2019, his most popular works were:

  • Nanoindentation investigation on the mechanical stability of individual austenite grains in a medium-Mn transformation-induced plasticity steel (82 citations)
  • A molecular dynamics study on the orientation, size, and dislocation confinement effects on the plastic deformation of Al nanopillars (54 citations)
  • Size effect on the deformation behavior of duralumin micropillars (47 citations)

In his most recent research, the most cited papers focused on:

  • Composite material
  • Thermodynamics
  • Metallurgy

Ahw Ngan mostly deals with Dislocation, Metallurgy, Nanoindentation, Composite material and Crystallography. His Dislocation study necessitates a more in-depth grasp of Condensed matter physics. The various areas that he examines in his Metallurgy study include Transmission electron microscopy and Plasticity.

His work is dedicated to discovering how Plasticity, Crystal twinning are connected with Nucleation and Compression and other disciplines. His work focuses on many connections between Nanoindentation and other disciplines, such as Elastic modulus, that overlap with his field of interest in Loading rate, Stiffness and Aluminium. His Crystallography research is multidisciplinary, relying on both Viscoelasticity and Grain size.
