Title: CASS Ferrite and Grain Structure Relationship

Abstract

This document summarizes the results of research conducted at Pacific Northwest National Laboratory (PNNL) to determine whether, based on experimental measurements, a correlation existed between grain structure in cast austenitic stainless steel (CASS) piping and ferrite content of the casting alloy. The motivation for this research lies in the fact that ultrasonic testing (UT) is strongly influenced by CASS grain structure; knowledge of this grain structure may help improve the ability to interpret UT responses, thereby improving the overall reliability of UT inspections of CASS components.

  • It is shown that the blunt notch Charpy impact properties of a V-5Cr-5Ti alloy are extremely sensitive to the grain size distribution developed during the final annealing treatment. Ductile behavior down to liquid nitrogen temperatures can be induced, for example, by a treatment at 950{degrees}C, rather than annealing at 1125{degrees}C. It is proposed that the resistance to irradiation-induced shift in DBTT reported by Argonne National Laboratory (ANL) researchers for the V-4Cr-4Ti alloy is related primarily to the exceptionally fine-grained microstructure developed during the low temperature processing route adopted for this alloy.
  • The research performed under this grant has been principally devoted to understanding and quantifying the relationship between the macroscopic electrical transport properties of ZnO based materials and the properties of their grain boundaries. Two forms of polycrystalline ZnO have been extensively investigated, polycrystalline thin films, such as are used as optically transmitting, conducting electrodes and as piezoelectric films, and polycrystalline bulk forms, such as are widely used as surge arrestors. The former are essentially two-dimensional and the latter three-dimensional. The research has included both simulation and experimental studies. The simulation studies have been primarily addressing how the macroscopic properties ofmore » bulk ZnO ceramics are determined by the electrical and crystallographic properties of their grain boundaries. The behavior of varistors has been the focus since the highly nonlinear electrical characteristics provide an opportunity to test the models in much greater detail than is possible if the characteristics were simply ohmic. Furthermore, there is a continuing desire to improve varistor characteristics, such as the sharpness of the switching voltage and the degree of nonlinearity, so the effect of grain boundary variations on these parameters have been specifically addressed and found to quantitatively depend on the variation in both grain size and grain boundary barrier height. New methods of quantifying the effect of microstructural variations on the I-V characteristics have been introduced. The simulations have included both electrical network methods and effective medium methods. During the course of the research, the studies were extended to describe electrical breakdown, specifically on how microstructural variations lead to current localization which in turn leads to a form of electrical discharge failure, a common form of failure of varistors under electrical loading.« less
  • A study was conducted on the effect of grain size, size of specimen and stress gradient on the direct stress fatigue strength of a 2.5 Al-magnesium alloy at room temperature. Specimens with three different grain sizes and seven different notch sizes were used in this investigation. The data are analyzed with regard to relationships between grain size, size of notch, relative stress gradient, stress gradient per grain, and theoretical strength of notched specimens. (auth)
  • The St. Regis Paper Company National site is partially located inside the City of Cass Lake, Minnesota. The identified site contaminants are polycyclic aromatic hydrocarbon (PAH) compounds, phenols specifically pentachlorophenol (PCP), and dioxin compounds. The on-site groundwater and soils for both areas are contaminated with PAH compounds, PCP, and several polychlorinated dibenzo-p-dioxins (dioxins). A surface-water body was found to be contaminated with low levels of PAH compounds but not PCP. Municipal wells were found to be contaminated with low levels of PAH compounds. The potential human exposure pathways for ground water include the ingestion, inhalation, and dermal absorption of PAHmore » compounds, PCP, and dioxins. The maximum levels of PAH compounds and PCP found in on-site soils are likely at levels of health concern. The human-exposure pathways associated with the surface-water channel are ingestion, inhalation of aerosols, and dermal absorption of PAH compounds. Food chain contamination is a possibility and may result from site contamination of the soil, ground water and surface water. The site is of potential health concern because of the risk to human health resulting from possible exposure to hazardous substances at concentrations that may result in adverse health effects.« less
  • The Agate Lake Scrap Yard has been operated from 1952 to the present. In 1986, the site was included on the National Priorities List. PCBs have been detected in on-site soil. Dioxins and furans, by-products of combustion, have also been detected in on-site soil. Volatile organic compounds (VOCs) have been detected in on-site ground water. Certain potential exposure pathways are evident at this time. Contact with areas of known soil contamination (including ash from the furnaces) is possible because access to these contaminated areas is currently unrestricted. The site owner is currently using water from a shallow sandpoint well. VOCmore » exposure is possible via this well water. Data are insufficient at this time to draw conclusions about whether contaminants from the site have impacted adjacent wetlands, Agate Lake, or consumable biota.« less
