摘要： An improved thermal history sensor having multiple polymeric substrates with unique compositions is disclosed. By positioning the sensor adjacent to an item subject to thermal stressors, each of the polymeric substrates react with a different rate of crystallization and thus yield a specific measure of infrared (IR) absorption spectra, for example. By comparing these measurements for each polymeric substrate, a thermal history fingerprint may be obtained. This thermal history fingerprint may then be compared to baseline data to yield information about the item, such as the expected remaining useful lifetime of the item.

摘要： An improved thermal history sensor having multiple glass ceramic substrates with unique compositions is disclosed. By positioning the sensor adjacent to a component subject to thermal stressors, each of the glass ceramic substrates react with a different rate of nucleation and crystal growth and thus yield a specific measure of opacity. By comparing these values representing the opacity for each glass ceramic substrate, or thermal history fingerprint, to baseline data, information about the expected remaining useful lifetime of the component may be obtained.

摘要： A reinforcing material is uniformly dispersed in a yttrium aluminum garnet matrix material for use as a machine tool material specially suited for machining Ti or a Ti alloy. The matrix material and the reinforcing material are present in proportions selected such that the machine tool material is substantially resistant to transfer of impurities to a Ti or Ti alloy by way of either chemical reaction with or diffusion into the Ti or Ti alloy material to be machined. The matrix material preferably comprises Y3Al5O12. The reinforcing material may comprise SiCw, TiC, TiN, TiB2, or combinations thereof and is preferably present in an amount sufficient to enable electrical discharge machining of the machine tool material. In addition, the machine tool material defines a thermodynamically stable phase at relatively high machining temperatures.
