Microstructural effects in abrasive wear. Quarterly progress report, June 1981-January 1982
This report describes research aimed at establishing quantitative relationships between microstructure and wear resistance of highly alloyed materials, including high-Cr white irons and powder metallurgy (PM) alloys now used or potentially to be used in coal mining, handling, and gasification. The specific types of wear under study are low-stress abrasion and gouging wear encountered in mining, coal conversion, and transfer applications. Recent work has concentrated on analysis of results. The many detailed observations obtained in the work on scratch test simulations of abrasive wear mechanisms have been summarized in drafts of three papers. The first, a study of abrasive wear mechanisms using diamond and alumina scratch tests, was included as an appendix to Quarterly Report 16/17 and has been accepted for publication in the journal Wear. Revision of the other two papers is in progress. Two papers representing our analysis of results are included as appendices to this report. The first, abrasion in multiphase alloys, was presented at the NACE conference on corrosion-erosion-wear of materials at Berkeley, California in January 1982, and will be published in the proceedings. The second, on a deformation-induced phase transformation during abrasive wear of Co-base alloys, is being submitted for publication in Metallurgical Transactions. In addition, work on the gouging abrasion resistance of the previously tested high Cr-Mo white cast irons is completed. The abstract of a short paper on the results is included as an appendix. (Note: since the appendices are, or will be, available in the open literature they have been removed from the report.)
