This book was released on 2016 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: To assist in the failure analysis of a rocket thruster, the ignition temperature in oxygen-enriched atmospheres of titanium and titanium alloys was investigated. The open literature indicated melting temperatures in the range of 1,660°C (3,020°F) and ignition temperatures ranging from 250 to 1,627°C (482 to 2,961°F) for titanium powder and solid titanium, respectively. Vertically mounted test samples of varying diameters were ignited by induction heating in 66 % oxygen (O2)/balance nitrogen (N2) and in 99.5 + % O2 at 1,000 psia. Ignition was measured by either a platinum/platinum-rhodium (Type S) thermocouple comprised of 0.05-mm (0.002 in.) and 0.076-mm (0.003 in.) diameter wires welded to the samples or by a two-color pyrometer. The ignition temperatures in 66 % O2 and 99.5 + % O2, with various surface treatments and configurations, ranged from 1,623 to 1,659°C (2,953 to 3,018°F). The lack of an effect on ignition temperature as a function of oxygen concentration suggests that the ignition process is controlled by subsurface rather than surface-related processes. One unexpected result was that although sample nitriding did not change the autogenous ignition temperature (AIT), it did change the rate of combustion after ignition.

Available in PDF, EPUB and Kindle. Book excerpt: A laser heating technique and facility have been developed to study metal ignition and combustion in high-pressure oxygen. The ignition and combustion temperatures, estimates of oxidation rates, and ignition and combustion morphology can be determined. This facility and the laser heating techniques are described. Examples of the type of data obtained are presented and discussed. The ignition temperature curves for an aluminum alloy--Unified Numbering System (UNS) A96061, a stainless steel--UNS S30200, and two nickel alloys--UNS N07718 and N04400 are given.

Available in PDF, EPUB and Kindle. Book excerpt: A summary is presented of a research program aimed at the improvement of high-temperature strain gages of the electrical resistance type. Potential ceramic and metal components were evaluated and a gage was devised that was based on these evaluations. This gage (NBS 5B) was flexible and easy to install; however, it lacked resistance stability at higher temperatures. In an attempt to minimize this deficiency, ceramic cements were developed that showed greater electrical resistivity than had been previously observed in the range 800 to 1800 degrees Fahrenheit; also, a technique was devised for increasing the resistance to ground by applying a fired-on ceramic coating to the grid of a specifically developed unbacked gage. A study was made of the cause of the erratic response of cemented gages that had not been preheated prior to use. There were strong indications that the erratic response was caused mostly by the rapid decrease in resistance that accompanied structural changes in the cement.
