Subcritical Crack Growth in Ceramic Composites at High Temperature Measured Using Digital Image Correlation

Description: An in situ experimental technique is described that allows high resolution, high sensitivity determination of displacements and full-field strains during high temperature mechanical testing. The technique is used to investigate elevated temperature crack growth in SiC/Nicalon sub f composites. At 1150 degrees C, the reinforcing fibers have a higher creep susceptibility than the matrix. Fiber creep leads to relaxation of crack bridging tractions, resulting in subcritical crack growth. Differenti… more

Reduced oxide soldering activation (ROSA) PWB solderability testing

Description: The effect of ROSA pretreatment on the solderability of environmentally stressed PWB test coupons was investigated. The PWB surface finish was an electroplated, reflowed solder. Test results demonstrated the ability to recover plated-through-hole fill of steam aged samples with solder after ROSA processing. ROSA offers an alternative method for restoring the solderability of aged PWB surfaces.

A laser scanning system for metrology and viewing in ITER

Description: The construction and operation of a next-generation fusion reactor will require metrology to achieve and verify precise alignment of plasma-facing components and inspection in the reactor vessel. The system must be compatible with the vessel environment of high gamma radiation (10{sup 4} Gy/h), ultra-high-vacuum (10{sup {minus}8} torr), and elevated temperature (200 C). The high radiation requires that the system be remotely deployed. A coherent frequency modulated laser radar-based system will… more

TWRS Privatization Phase I waste characterization data evaluation for the request for proposal

Description: Radioactive wastes have been stored in large underground tanks at Hanford since 1944. In 1991, The Tank Waste Remediation System (TWRS) program was established to manage, retrieve, treat, immobilize, and dispose of these wastes in a safe, effective manner. DOE believes that it is feasible to privatize portions of the TWRS program. Under the Privatization strategy embodied in the request for proposal, DOE will purchase services from a contractor-owned, contractor-operated facility under a fixed-… more

Effect of Composition and Processing on the Thermal Fatigue and Toughness of High Performance Die Steels. Year 1 Report

Description: The goal of this project is to extend the lifetime of dies for die casting by 20%. Since the die contributes about 10% to the cost of die cast parts, such an improvement in lifetime would result in annual savings of over $200 Million dollars. This is based on the estimated annual die production of one Billion dollars in the US. The major tasks of this two year project are: (1) Evaluate NEW DIE STEEL COMPOSITIONS that have been developed for demanding applications and compare them to Premium Gra… more

High heat generation safety issue in tank 241-C-106

Description: A `White` paper was written on the High Heat Generation Safety Issue in Tank 241-C-106. The issue is if tank 241-C-106 should start leaking, the lack of alternative cooling methods will require continued addition of water and thereby possibly increase the amount of leakage to the ground. If the current methods of cooling the tank are stopped, the sludge and concrete structure will heat to temperatures greater than established limits and may cause structural damage, leading to dome collapse and … more
