This thesis examines the formation of martensite in Ni-based super-alloys in both an alloy-coating system and in the bulk alloy, NiPtAl. The alloy-coating study was designed to test the hypothesis that an extra layer of ...

The residual stress distributions in two 7449 aluminium alloy rectilinear blocks have been determined using neutron diffraction. Heat treatment included cold water immersion quenching and a period of precipitation hardening. ...

The use of traditional two-dimensional (2D) fibre preforms can be associated with poor out-of-plane and interlaminar mechanical performance, particularly in response to impact loads. Such preforms comprise multiple plies ...

Water purification technologies such as microfiltration/ultrafiltration and reverse osmosis utilize porous membranes to remove suspended particles and solutes. These membranes, however, cause many drawbacks such as a ...

PCR is a common and often indispensable technique used in medical and biological research labs for a variety of applications. Real-time quantitative PCR (RT-qPCR) has become a definitive technique for quantitating ...

In this paper, a nite-element modelling framework is presented with explicit representation of polycrystalline microstructure for a tempered martensite ferritic steel. A miniature notched specimen was manufactured from ...

Despite all current measures taken to assure their safety, aircraft are still crashing. Since 1944 there has been a global organization, International Civil Aviation Organization (ICAO), focused on providing rules for ...

Contamination caused by insects on aircraft leading edge surfaces can result in premature transition of the boundary layer, leading to an increase in skin friction drag and fuel consumption. Consequently, the use of novel ...

Physical risk factors and their combinations are linked to the causation of Musculo Skeletal Disorders (MSDs) which has implications for on-site operator productivity. Current risk assessment methods have no element to ...

The basic innovation proposed in this work is to consider one of the two coefficients of the Armstrong and Frederick (AF) evolution equation for the back stress, function of another dimensionless second order internal ...
