The structural and stress changes in molybdenum/amorphous silicon (Mo/a-Si)
EUV reflecting multilayers during annealing at 316°C were studied. The amorphous
interlayers, with an Mo:Si stoichiometry of 1:2, grew during annealing. The residual
stresses in each component of the multilayer also changed significantly. Through high
resolution electron microscopy, selected area electron...
All carbon steel that is used in tools, springs,
and machine parts where tempering is necessary undergoes
three distinct heat treatments: first, heating for forging;
second, heating for hardening; and third, heating
The current knowledge on the microstructural evolutions and mechanical properties of selective laser melting (SLM) produced H13 tool steel components is limited. This research is focused on optimization of SLM processing parameters for H13 tool steel and investigation of microstructure and mechanical properties of H13 tool steel components after SLM...
The temperature-time-location relationships during steam conditioning and pressure
treatment of timber poles have been studied and mathematical models that take into
account both the thermal properties of the poles and the parameters of the treatment
process have been developed. Although much work has been previously done in this
Ultra high temperature (UHT) processing can extend shelf life of milk to several months without refrigeration, which is more convenient and energy saving than pasteurized milk. However, the poor acceptance caused by "cooked" flavors limits its marketing growth, especially in United States. Ohmic heating, which has a more uniform and...
CPM-M4 tool steel is a commonly used knife blade material due to its high strength and wear resistance. The goal of this thesis is to understand how heat treatment parameters affect blade performance and microstructure.Five heat treatments were applied to CPM-M4 steel by varying austenitizing and tempering temperatures. The microstructures...
