Thermal cycling of Ti46Al8Nb1B

open access: yesIntermetallics, 2006
Abstract The effects of thermal cycling on the mechanical properties and microstructure of a TiAl-based alloy (Ti46Al8Nb1B) have been investigated for samples with and without an imposed external stress. The temperature range (300–800 °C) and stress (0 or 300 MPa) were chosen to reflect likely industrial usage.

Mechanical property and structural changes by thermal cycling in phase-separated metallic glasses

Journal of Materials Science and Technology, 2021
Nondestructive cryogenically thermal cycling has been a simple but effective treatment to enhance mechanical properties of glassy materials. However, how the structural heterogeneities on nanometer scales are affected by thermal cycling is still an issue.

The effect of thermal cycling on the fracture toughness of metallic glasses

open access: yesActa Materialia, 2020
A wide range of behaviors, including non-monotonic rejuvenation and relaxation, and the ability to qualitatively change the effect by varying the structural state of the glass was observed during thermal cycling of bulk metallic glasses.

Characterization and effects of thermal cycling on the properties of paraffin/expanded graphite composites

open access: yesRenewable Energy, 2020
Paraffin has been one of the most potential phase change materials (PCMs) in low-temperature latent heat storage. However, the low thermal conductivity of paraffin restricts its thermal performance and limits its large-scale applications.

Delamination mechanism of thermal barrier coatings induced by thermal cycling and growth stresses

, 2021
The growth of thermally grown oxide (TGO) is often regarded as a key factor causing failures of thermal barrier coatings (TBCs) because it leads to thermal cycling and growth stresses.
