摘要： This invention relates generally to a novel method of manufacturing a composite body, such as a ZrB.sub.2 --ZrC--Zr (optional) composite body, by utilizing a post-treatment process and to the novel products made thereby. More particularly, the invention relates to a method of modifying a composite body comprising one or more boron-containing compounds (e.g., a boride or a boride and a carbide) which has been made by the reactive infiltration of a molten parent metal into a bed or mass containing boron carbide, and optionally one or more inert fillers, to form the body.

摘要： This invention relates generally to a novel method for removing metal from a formed self-supporting body. A self-supporting body is made by reactively infiltrating a molten parent metal into a bed or mass containing a boron donor material and a carbon donor material (e.g., boron carbide) and/or a boron donor material and a nitrogen donor material (e.g., boron nitride) and, optionally, one or more inert fillers. Once the self-supporting body is formed, it is then subjected to appropriate conditions which causes metallic constituent contained in the self-supporting body to be at least partially removed.

摘要： A method and associated apparatus for carrying out fluidized bed combustion and transferring heat produced thereby to a boiler includes providing a fluidized bed of particulate matter and introducing fuel particles thereinto, causing a portion of the fluidized bed constituents to flow upwardly through a heat exchanger which is essentially free of any obstructions to said flow, and reintroducing the portion of fluidized bed constituents which flow through the heat exchanger, back into the fluidized bed. As preferably embodied, the portion of fluidized bed constituents flows into an inlet at the bottom of the heat exchanger from a quiescent zone adjacent the combustion bed and a gas having a combustible component is introduced into the heat exchanger. Advantageously, additional fuel particles are also introduced into the heat exchanger to flow upwardly therethrough. Also advantageously, the cross-sectional area of the flow path provided in the heat exchanger is proportioned to provide an essentially uniform temperature profile across the flowing particles at any position in the heat exchanger.

摘要： A fatigue-resistant Nitinol instrument has a working portion in the deformed monoclinic martensitic state and an austenite finish temperature in the range of 40° to 60° C. Because the operating environment of the instrument is about 37° C., the working portion remains in the monoclinic martensitic state during its use. The relatively high austenite finish temperature and fatigue resistance is achieved by subjecting the nickel-titanium alloy to a final thermal heat treat in a temperature range of about 410° to 440° C. while the nickel-titanium alloy is under constant strain of about 3 to 15 kg. Further, the high austenite finish temperature is achieved without subjecting the alloy to thermal cycling to produce shape memory. Additionally, there are no intermediate processing steps occurring between obtaining a finished diameter of the wire or blank through cold working and the final thermal heat treat under constant strain.
