Effect of intermetallic compounds distribution on bonding strength of steel–aluminum laminates

Materials & Design, 2022
In this study, steel–Al laminates are prepared via hot-roll bonding and annealed for various durations to generate intermetallic compounds (IMCs) with different distributions at the interface.

Tensile and bend behaviour of nanostructured HVOF and flame sprayed stellite coatings

MATEC Web of Conferences, 2018
Stellite 6 powder (CoCrSiW) was deposited using flame spray (FS) and high velocity oxygen fuel (HVOF) techniques on steel substrates. The microstructure of stellite coatings produced with these deposition techniques displayed a rather similar morphology ...

Effect of thermal cycling frequency on the durability of Yb-Gd-Y-based thermal barrier coatings [PDF]

, 2019
The effects of thermal cycling frequency and buffer layer on the crack generation and thermal fatigue behaviors of Yb–Gd–Y-stabilized zirconia (YGYZ)-based thermal barrier coatings (TBCs) were investigated through thermally graded mechanical fatigue ...

Mechanisms of Multi-Path Runoff Leakage Induced by Cracks at the Rock–Soil Interface on Bedrock-Exposed Slopes in Karst Critical Zones

Hydrology
As exposed bedrocks commonly interface with the soil directly, lacking a transition layer, cracks at rock–soil interface cracks (RSI-Cracks), are well-developed, particularly following wet–dry alternation in karst critical zones.

Crack-Growth Behavior in Thermal Barrier Coatings with Cyclic Thermal Exposure [PDF]

, 2019
Crack-growth behavior in yttria-stabilized zirconia-based thermal barrier coatings (TBCs) is investigated through a cyclic thermal fatigue (CTF) test to understand TBCs’ failure mechanisms.

Off-fault tensile cracks: A link between geological fault observations, lab experiments, and dynamic rupture models [PDF]

, 2012
We examine the local nature of the dynamic stress field in the vicinity of the tip of a semi-infinite sub-Rayleigh (slower than the Rayleigh wave speed, c_R) mode II crack with a velocity-weakening cohesive zone. We constrain the model using results from

An overview of tensile and shear failure mechanisms of silicon carbide-based ceramic matrix composites

Journal of Materials Research and Technology
The successful applications of silicon carbide-ceramic matrix composites (SiC-CMCs) in aeronautical and aerospace industries require deeper understanding of their mechanical behaviors and failure mechanisms.

Size scaling of strength in thin film delamination

, 2011
We investigate by numerical simulation the system size dependence of the shear delamination strength of thin elastic films. The films are connected to a rigid substrate by a disordered interface containing a pre-existing crack. The size dependence of the

Interface crack between dissimilar one-dimensional hexagonal quasicrystals with piezoelectric effect [PDF]

, 2019
In this paper, an interface crack between dissimilar one-dimensional (1D) hexagonal quasicrystals with piezoelectric effect under anti-plane shear and in-plane electric loadings is studied. By using integral transform techniques, the mixed boundary value
