Thermal Elastic-plastic Stress Analysis of Steel Fiber Reinforced Aluminum Metal-matrix Composite Arches
A thermal elastic-plastic stress analysis is carried out on steel fiber reinforced aluminum metal-matrix composite arch under uniform temperature distribution. The arch is fixed at both ends. The composite material is assumed to be strain hardening linearly. First yielding temperature, thermal residual stresses and the distribution of these stresses under thermal loading are investigated by usi...
متن کاملFatigue and fracture of a 316 stainless steel metal matrix composite reinforced with 25% titanium diboride
Fatigue and fracture mechanisms have been studied in a steel-based metal matrix composite (MMC), comprising a 316L austenitic matrix reinforced with 25 wt% particulate titanium diboride (TiB2). The fracture toughness was determined in the as-HIPped condition as being slightly below 30 MPa√m. Fatigue crack growth rates have been determined, and corrected for the effects of crack closure. The fra...
متن کاملEffect of Cladding Direction on Residual Stress Distribution in Laser Cladded Rails
In this investigation, a laser cladding process with a powder feeding was used to deposit stainless steel 410L (high strength, excellent resistance to abrasion and corrosion, and great laser compatibility) onto railhead (higher strength, heat treated hypereutectoid rail grade manufactured in accordance with the requirements of European standard EN 13674 Part 1 for R400HT grade), to investigate ...
متن کاملResidual Stresses in Rotating Steel Cylinders with Composite Surface Layers
After undergoing a manufacturing process, materials may exhibit internal stresses referred to as residual stresses. In steel-composite hybrid structures, residual stresses are typically formed due to the unequal thermal behaviour of the steel and composite. Thus, knowledge of the residual stress state is important in the assessment of the external-internal loading in steel-composite hybrid stru...
متن کاملEvaluation of titanium carbide metal matrix composites deposited via laser cladding
Metal matrix composites have been widely studied in terms of abrasion resistance, but a particular material system may behave differently as particle size, morphology, composition, and distribution of the hardening phase varies. The purpose of this thesis was to understand the mechanical and microstructural effects of combining titanium carbide with 431 series stainless steel to create a unique...
