Handbook of Environmental Fate and Exposure Data for Organic Chemicals

Abstract: Volume I in this series deals with organic chemicals that fall into the category of large production volumes and priority pollutants. This reference work is well organized and easy to follow. It provides not only data but a brief discussion of particular topics such as log octanol/water partition coefficient, biodegradation, abiotic degradation, and bioconcentration. The author's description of each of these topics extremely helpful, especially to those using these types of data for the first time. However, all terms used in these sections are not defined. While there are some minor differences in some physical data between this and other reference books, the author supplies the reference with the data, allowing one to easily find the original source. It is also important to realize that, while this is a good reference book, for fate and exposure data, no aquatic toxicity data are listed.

Reexamination of ASTM C 1202 : Standard test method for electrical indication of concrete's ability to resist chloride ion penetration

Abstract: The electrolytic processes in the ASTM C 1202 chloride penetration test method have been reexamined both theoretically and experimentally The analyses show that hydroxyl (OH−) ion generated at the cathode during testing carries a substantial part of the current and that chloride (Cl−) ion is not the sole current carrier Attention has also been drawn to the implication of the experimental results on the determination of the Cl− ion diffusivity by the ASTM C 1202 experimental setup

A damage function and associated failure equations for predicting hold time and frequency effects in elevated temperature, low cycle fatigue

Abstract: A new approach is developed for predicting strain-controlled, low cycle fatigue life at elevated temperature using a proposed energy measure of fatigue damage. This measure of damage, defined as the net tensile hysteretic energy of the fatigue cycle, can be approximated by the damage function σTΔep, where σT is the maximum stress in the cycle and Δep is the inelastic strain range. The damage function is applied to predicting effects of hold time and frequency, when time-dependent damage occurs, through failure relations incorporating a variation of Coffin's frequency modified approach. Failure equations are developed for two postulated categories of time-dependent damage.

A simple method for studying slow crack growth.

Abstract: A simple, inexpensive method for studying slow crack growth is described. The method entails measurements of load relaxation at constant displacement using a double torsion specimen. It is demonstrated that the data generated using this technique are in excellent agreement with data obtained using the more complex conventional techniques, for a range of materials - steel, titanium, glass, aluminum oxide, PMMA. These encouraging initial results suggest that additional and more detailed studies using this test procedure are merited.

Theory and application of a micro-scale abrasive wear test

Abstract: A micro-scale abrasion test has recently been developed that allows measurement of the wear resistance of the surface regions of a material. The typical penetration depth is less than 30 μm. The test uses a simple mechanical and optical system and involves rotating a hard steel sphere against a specimen in the presence of small abrasive particles. The method has been used to investigate the wear resistance of thin PVD coatings (1 to 5 µm), metallic glass ribbons, and paint films in addition to bulk samples of metals, ceramics, and glasses. The associated theory has been extended so that results may be obtained from any curved surface. This furthers its applicability to practical surface-engineered components such as twist drills, bearings, turbine blades, and biomedical prostheses. A detailed characterization of the experimental procedure has been undertaken to provide an understanding of the repeatability and sensitivity of the test. In a study of cutting-tool coatings, the wear resistance measured by this method has been shown to correlate with scratch test response and with the performance of coated end-mills in cutting tests.
