Effects of selected minor alloying additions on the structure deformation characteristics of beryllium

Creator:: Dooley, George Joseph, III
Abstract:: Solid solution alloying was employed in an attempt to produce some relatively ductile form of beryllium. If the c/a ratio could be significantly altered, it was felt new or different slip systems could be activated. The following elements were selected on the basis of atomic size, melting point, crystal structure...

The effect of alpha phase morphology on the impact energy of commercial purity titanium

Creator:: York, James Michael
Abstract:: Samples of commercial purity titanium were heat treated above the beta transformation temperature and within the two phase alpha-beta phase field, followed by cooling at varying rates. Testing of the samples in tension and by instrumented impact indicated that some strengthening could be imparted by these heat treatments, although at...

Measurement and scrubbing of SO₂ and NOx from boiler flue gases

Creator:: Reichel, Rolf Hubertus
Abstract:: At the Oregon State University heating plant the primary source of heat energy is natural gas with crude oil as the standby supply of fuel. In the future, as natural gas becomes a rarer commodity, more reliance will be placed on the use of the more expensive, more polluting, but...

Control of peak stresses in tensile testing machine components subjected to shock loading

Creator:: Mitchell, Jack Alan
Abstract:: The mechanical properties of materials at cryogenic temperatures have been the subject of increasing interest during the past few years, although very little actual materials testing has been done at extremely low temperatures because of the high cost and low heat of vaporaization of liquid helium. Recently, the Department of...

Heat Treatment Effects on the Mechanical Properties and Microstructure of CPM-M4 Tool Steel

Creator:: Fast, Cody P.
Abstract:: Variations in heat treatments have significant effects on the microstructure of tool steels. For CPM-M4 tool steel, the changes in microstructure and mechanical properties were observed based off of variations in temperature. Five heat treatments with constant exposure time and variable austenitizing and tempering temperatures were performed on samples of...

Experimental combustion analysis and development of representative fuel specifications for selected wood and refuse derived fuel pellets from the Pacific Northwest

Creator:: Haluzak, Charles Craig
Abstract:: An experimental biomass combustion facility has been built and established at Oregon State University. The furnace, or Biomass Combustion Unit ( BCU ), uses an augertype fuel feed system, grate-type fuel support with under and over fire air supply. Fourteen pellet species from five States - Alaska, Washington, Oregon, Idaho,...

Catastrophic propagation of ductile cracks in metallic foils

Creator:: Elliott, Leonard Thomas
Abstract:: The sudden failure of metal structures under load, which has been a design problem for many years, is characterized by a crack propagation rate which approaches the speed of sound in the material. These failures, which are often known as catastrophic fractures, may be divided into two types which depend...

The Effect of Isothermal Aging on the Development of Long-Range Order in Ni-based Alloys

Creator:: Aerne, Nicholas S. J.
Abstract:: Nickel (Ni)-based alloys with a high chromium (Cr) content are frequently employed in applications where elevated temperatures and/or corrosive environments are present due to their excellent corrosion resistance and mechanical properties. However, a gap exists around the formation, and kinetics of long-range order (LRO) Ni2Cr phase in both model binary...

Learning approaches for the early detection of kickback in chainsaws

Creator:: Arnold, Drew D.
Abstract:: Among the many safety hazards facing chainsaw operators, the phenomenon known as kickback is the most dangerous. Kickback occurs when the chain at the tip of the chainsaw is caused to stop abruptly, and transfers the energy of the cutting chain to motion of the saw. The saw will rotate...
