An in-situ TEM investigation of He bubble evolution in SiC
This paper presents work using the capabilities of two TEM with in-situ ion irradiation facilities: Microscope and Ion Accelerator for Materials Investigation (MIAMI) at the University of Huddersfield and Joint Accelerators for Nano-science and Nuclear Simulation JANNuS at Centre de Spectrométrie Nucléaire et de Spectrométrie de Masse (CSNSM), Orsay, France, to study the nucleation and growth o...
متن کاملFabrication of Ti3SiC2-SiC max phase composites via in-situ and ex-situ synthesis
Recently, a series of three-component compounds with the combination of Mn+1AXn known as Max phases have been considered as a new material. One of the most important features of Max phases, is the self-healing property of them. The main reason for considering Max Phases is a unique collection of unusual properties including their metallic, ceramic, physical, and mechanical properties. One of th...
متن کاملIn situ Observation of Microstructure Evolution in 4H-SiC under 3.5keV He Irradiation
4H-SiC was irradiated with 3.5 keV He ions using the MIAMI facility at University of Huddersfield. The evolution of microstructure and gas bubbles during the irradiation at 700°C, 800°C and 900°C was observed by in situ transmission electron microscopy. Under irradiation, isolated bubbles and bubble discs formed in the SiC matrix. Bubble discs lying on {0001} and {10-10} crystal planes were beg...
متن کاملAn In-situ Tem Study of the Effects of 6 Kev He Ion Irradiation on Si and Sio 2
Using the new MIAMI facility at the University of Huddersfield, an in-situ TEM study has been carried out on the effects of helium implantation on a tri-layer system consisting of monocrystalline silicon (c-Si), silicon dioxide (SiO2) and polycrystalline silicon (poly-Si). Co-irradiation of these three components enabled direct comparisons to be made of differences between the response of c-Si ...
متن کاملEffect of Helium-Neon Laser Irradiation on Motility and Ultrastructure of Fresh and Frozen-Thawed Human Sperm
Purpose: Semen freezing is an important technique in human infertility treatment in many different patients but it damages sperms. Low-power lasers are physical agents that have biostimulatory effects. In this study, low-power helium-neon laser's (16J/cm2, one time irradiation) effect on motility and ultrastructure of fresh and frozen-thawed human sperm were studied. Materials and Methods: Thi...
