Quantitative TEM Tensile Testing on 1D Nano-structural Materials

Correction: Quantitative in situ TEM tensile fatigue testing on nanocrystalline metallic ultrathin films.

The authors have found an error in the post-processing scheme to calculate the stress–strain curves from the raw electrical data (ΔC1 − ΔC2 vs. Vin, with and without the specimen). The scheme consists of calculating X A (using eqn (6)), from which ΔC1 is known (using eqn (1)). ΔC2 is then determined knowing the measured ΔC1 − ΔC2 value, from which XLS can be determined using eqn (1). The calibr...

Quantitative in situ TEM tensile fatigue testing on nanocrystalline metallic ultrathin films.

A unique technique to perform quantitative in situ transmission electron microscopy (TEM) fatigue testing on ultrathin films and nanomaterials is demonstrated. The technique relies on a microelectromechanical system (MEMS) device to actuate a nanospecimen and measure its mechanical response. Compared to previously demonstrated MEMS-based in situ TEM techniques, the technique takes advantage of ...

Quantitative in situ TEM tensile testing of an individual nickel nanowire.

In this paper, we have demonstrated the usage of a novel micro-mechanical device (MMD) to perform quantitative in situ tensile tests on individual metallic nanowires inside a transmission electron microscope (TEM). Our preliminary experiment on a 360 nm diameter nickel nanowire showed that the sample fractured at an engineering stress of ∼ 1.2 GPa and an engineering strain of ∼ 4%, which is con...

Source Truncation and Exhaustion: Insights from Quantitative in situ TEM Tensile Testing

A unique method for quantitative in situ nanotensile testing in a transmission electron microscope employing focused ion beam fabricated specimens was developed. Experiments were performed on copper samples with minimum dimensions in the 100-200 nm regime oriented for either single slip or multiple slip, respectively. We observe that both frequently discussed mechanisms, truncation of spiral di...
