... on pure aluminum Al-99.999 using high-speed and scanning electron microscope photography were observed. The eroded surface morphology was in the form of large swellings (hundreds of micrometers), which embodies the plastic flow. Results indicate that large swelling regions formed in a few seconds...

..., the copper material will be pushed aside and the gas flow channel will be narrowed due to the plastic flow of the copper gasket. Figure 10a shows a schematic representation of such plastic flow of the gasket material. Δ A 1 + Δ A 2 is the sum of cross-sections of the gasket, which flows...

... in the plastic flow regime. Shoulder-shoulder asperity contact gives rise to a slanted contact force comprising tangential and normal components. Each force component comprises elastic and plastic terms, which upon statistical summation yields the force component for the elastic and plastic forces...

... . The wear rate in the 1 – 10 MPa regime was found to be very small and within the measuring instrument resolution and also insensitive to contact pressure. The regime is designated ultramild wear. Lack of plastic flow, minimal fragmentation of silicon particles, and the presence of undistorted voids...
