 | Unfuzed M15 and M19 mines are present in different proving grounds and test ranges, both as intended and unintended targets for testing of various munitions and weapon systems. There is a concern that these unfuzed mines may be accidentally driven over by various Army vehicles (HMMW, Bobcats, etc.). Composition B is typically the explosive found in these mines and also in many gun launched projectiles (i.e., 155-mm artillery, 3O-mm grenades, ... |

| Military live-fire training missions utilize a variety of energetic materials that are never completely consumed during firing. In February 2007, the U.S. Army Cold Regions Research and Engineering Laboratory teamed with the Vermont National Guard at Camp Ethan Allen to conduct tests to determine the propellant residues deposition related to the firing of small arms. Samples were collected from the snow surface at the firing points for 5.56-, 7.62-, 9-, ... |

|
| In the outdoor measurement facility, a certain amount of real estate is owned by the organization, and therefore can be groomed to keep clutter contributions to a minimum. As the transmit signal travels further down range, however, returns from long-range clutter sources are inevitable and can have a significant impact on measurement accuracy. This research effort investigates the effectiveness of employing nonlinear suppression (NLS) to abate long-range ambiguous clutter in ... |

Today, the average cost to put a payload in low earth orbit ranges from $4,400 to $10,000 per pound. Based upon the commercial market elasticity for new and emerging systems, the launch cost needs to decrease by 50 to 75 percent to create significantly ... |

| The present research investigates the effect that the breadth of expectancies have on satisfaction with performance. Although some scholars have suggested that expectancy should be conceptualized in terms of several plausible estimates of success, past research has operationalized expectancy as a person's single estimate of his or her probability of success. In contrast in the present study expectancies are conceptualized as involving a range of plausible expected outcomes. An experiment ... |

|
| The development of the microstructure of nitrided 20Cr-25Ni-1.8Ti stainless steel through primary creep at 160 MPa and 1173 K is investigated. Up to about 3% strain the dislocation density in the matrix increases, but thereafter falls. Dislocation tangles are generated around TiN particles as strain proceeds, and are to some extent replaced by subgrain boundaries towards the end of primary creep at about 11%. At less than 3% strain the ... |

| The annealing response of specimens of TiN dispersion hardened 20Cr-25Ni stainless steel after primary creep to a range of strains at 160 MPa, 1123 K is described. There is a driving force not only for reduction of the density, but also for an increase in perfection of the creep-induced matrix dislocation network. Moreover, it is shown that there is a driving force for the recovery of the dislocation tangles which ... |

| Authors:
S. Kikuchi; B. Ilschner
|
| The creep strength of AISI 304 stainless steel can be improved by a small prestrain at high temperatures. In the initial deformation stage, the creep rates show a remarkable decrease by prestraining. The minimum creep rates are also influnced by the amount of prestain through the difference of substructure and the precipitation of M(sub 23)C(sub 6) carbides. Another characteristic of the prestrained specimens is that they assume a constant creep ... |

| Amorphous ribbons of composition Co-5Fe-10Ni-11Si-16B, of width 2-3 mm, and a thickness of 40 microns were produced by the melt-spinning technique. The magnetization curves and the coercive field were measured by Forster in a coercimeter in an earth field compensated solenoid on ribbons of length 3 c. After annealing the specimen in a transverse magnetic field, the induced anisotropy was derived mathematically. |

Optical metallographic investigation of the resultant ingot showed that the alloy was essentially single-phase with traces of a second phase presumed to be aluminum solid solution. Small quantities of the alloy were rapidly solidified by melt spinning to obtain few meters of thin ribbons. These were studied ... |

G. Habchi; S. K. Marya
|
| The geometry of the electrode in GTA welding modifies the weld solidification cracking susceptibilities of 304 and 316L grade steels. Compared to the conical electrodes used so far, the sharp edge electrodes, particularly the welding procedure reduces the crack susceptibilities. However, the determining factor that conditions the weld metal solidification cracking is not proposed in this limited study. |
