Thermal Explosion Reaction in the Ti-C System under Air Atmosphere
Nov 01, 2009; ... The ignition temperature of the thermal explosion reaction from the Ti-C system under air is much lower than that under Ar atmosphere. The ignition mechanism for the Ti-C system under air is determined to be a mechanism of chemical oven, and the reaction mechanism is dissolution, reaction, and ...
Effect of Yttrium on the Fatigue Behavior of Investment-Cast and Wrought Ti-6Al-4V
Nov 01, 2009; ... The effect of yttrium (Y)-containing particles on the microstructure and fatigue behavior of investment-cast and hot isostatically pressed (HIP) Ti-6Al-4V has been investigated. Elemental Y was added to the Ti-6Al-4V melt to obtain a concentration of 200 ppm Y. which is 4 times the amount ...
Effect of Aging on the Fracture Behavior of Lean Duplex Stainless Steels
Nov 01, 2009; ... The influence of aging in the range of 550 °C to 850 °C for 5 to 120 minutes on the impact fracture behavior of 2101 and 2304 lean duplex stainless steels (DSS) was investigated in the present study. The 2304 steel displayed ductile behavior irrespective of aging conditions. In contrast, the ...
Abnormal Growth Transport in Oxide Scales on Fe-16Cr Steels in Water Vapor
Nov 01, 2009; ... The oxidation behavior of Fe-16Cr steels in N^sub 2^-12 vol pet H2O was studied at 850 °C. The oxide scale was compact and had excellent adhesion to the substrate; moreover, there were three layers of different compositions existing in the scale. To gain an insight into the transport mechanism, ...
Elementary Transformation and Deformation Processes and the Cyclic Stability of NiTi and NiTiCu Shape Memory Spring Actuators
Nov 01, 2009; ... The present work addresses functional fatigue of binary NiTi and ternary NiTiCu (with 5, 7.5, and 10 at. pct Cu) shape memory (SM) spring actuators. We study how the alloy composition and processing affect the actuator stabilily during thermomechanical cycling. Spring lengths and temperatures ...
